I'm wondering if anyone else has ever experienced the smelly water problem we are having. We have a continuing problem with the sink in our bathroom and smelly water. About once a month the water coming from both faucets starts to smell like sulfer. After doing some internet search, I read that the smell is due to bacteria. It is only the water coming out of the bathroom sink that smells. None of the other faucets or shower ever have the smell. We run bleach through that faucet and it will be good for about a month. Then the smell returns and we do the bleach thing again.
Any ideas or suggestions on why this is happening or how to solve it for good. We are stumped!

Dont know what year your unit is or what region your in but..................flush the hot water heater and change the calrod......remove & clean faucet airator cartridge or just replace and most of all make sure you are using a decent dual type water filter system.....hope this helps

Try checking your freshwater tank for discoloration and build up.....altho on most units this should be bypassed when on shore setup you could have a bad checkvalve and it is mixing...
durring my career I have seen so many tanks that people did not know that they needed to be sanitized & cleaned........cleaning on these tanks should be done while the coach is in motion so the sanitizer can swish & clean the tank and depending on the region of water intakes should be done several times a year.......only fill the tank to half capacity when doing it.......This allows the salution to agitate in the tank and loosen most of the scale and buildup....at your destination you just have to flush it twice and away you go!!
I also would sugest doing your waste tanks durring every travel and adding several bags of Ice down the commode to loosen up solids and waste that have accumulated on the tank and sensors.....

Make sure your vent is working also. Often there will be a Pro Vent under the bathroom sink, if it is not functioning properly you might be getting a smell from the grey tank.

I also have the same issue in our Montana and have not been able to figure it out either. Let's hope that some one has had this problem and figured this out. I do know that when I get the smell if I let the water run a little the smell will go away. but if it sits again for awhile it will return again.

Gene....I second that on the mechanical vent under the sink ,I forgot all about it...(guess mine is still working). As far as bacteria build up .....all faucets would have the smell if this was the problem.
I would right off follow genes advice...a mechanical vent is available in some states in home depot and definitly at all rv supplies
I also would clean the trap below the sink......mold buildup in the trap would also cause this problem due to hair and soap scum staying in the trap and causing wicking..

If the smell is a rotten egg smell.....it is sulfer , it is either the water source or again Drain the hot water heater....and clean or change the Calrod. or if you are in a region or just left one that is pulling well water....south eastern or western states....or well water with swamp areas outside of the camp area you are in
of course I could be wrong seeing Im not there to look at it............26 yrs as aLic. Plumber HVAC/R and 20 years doing RV services........simple fix , flush system, sanitize....change water filters ........
free advice goes along way.......
If this method doesnt work , call out a service truck ......he will flush the system ,sanitize....change the filters and gladly charge you a couple hundred bucks!!!!!!
people only question free advice........yet if you charge them they will argue forever how simple it was to do......and show you exactly how long it took you to do it!!!!!

Thanks for the responses. We have a filter on the outside at the hose. We have checked the trap under the sink. I don't know how all of this stuff works, but it is definitely the water that smells, not the sink area. When we bleach it, the smell goes away for about a month and then comes back. Bleaching again fixes it for about another month. Could this be trap related? We have a 2008 Jayco Designer. The smells comes out of both hot and cold water so we don't think it is the water heater either. Maybe we're wrong. This is just very annoying and somewhat frustrating.
eagleshea said
08:28 PM Sep 17, 2012
I have to agree with K & E. I don't think it is the trap or the waste tanks. It is actually the water that is coming out of the faucet. Seems to be something that happens if the water sits in the water lines for a few hours or something to do with the faucet.
K & E said

We appreciate the advice on this forum and do not doubt the expert knowledge of many of the contributors. I just thought there might be someone who has had a similar problem. After looking at our owner's manual information, we don't think our water heater has a rod in it. However, we've never looked. We're having some service done on our awning next week, and I will ask the dealer if they can check for us to see if we have the rod.
The strange thing is that the smell only comes from the water in our bathroom sink. We've never had in in the shower or kitchen sink which also use hot water regularly. Same thing with the tanks. If it was a problem with either of those things wouldn't you think it would be happening at all faucets.
This surely has us stumped. Again, thanks for any advice given. We all learn from listening to each other!!

first Draw of standing water after roughly 12 hours of standing and being heated will be the bathroom area(we all head there first).....water from campground and unkown sourcing can contain sulfer and this is frequent within the rv industry , plus water gases when it is heated and creates hydrogen and oxygen....it also creates calcium and other mineral build ups within your tanks and lines..........the easiest method for cleaning the tank without disassembly would be to shut the water off and remove the drain plug completely....do not just open the pet**** valve...
PLEASE MAKE ABSOLUTELY SURE YOU HAVE ALLOWED THE TANK TO COOL......SUGGEST SHUTTING IT OFF AND RUNNING IT UNTIL IT PURGES COLD AT THE FAUCET!!!!!
Once the tank is drained take a garden hose with a spray nozzle on it and spray with force thru drain port hole.....do this several times to loosen up debri in tank and flush it out dthis will get the trash that causes the smell out of the tank.....then go inside remove airater filter from bath room and kitchen faucet. start the water purge from the tub faucet until cleared...then do bath and kitchen......change inhouse filter and you should be good to go

But does that explain the "smelly water" coming ONLY from the bathroom faucet?
If I am understanding the thread correctly, it doesn't stink in the shower nor the kitchen faucet, only the bathroom faucet. It's not the trap, it's the water coming out of that one faucet only.
That's IF I understand the problem correctly.
I don't have the answer since I don't have an RV as of yet but it seems like the subject was getting turned to the tanks. If it was in the fresh water tanks, wouldn't the water coming out of the kitchen faucet or the shower head also stink? If it were the water heater, wouldn't the kitchen and shower water stink? It seems to be only the bathroom faucet.

I'm no expert like many here on this site, but this is exactly what i'm trying to prevent. In my previous post, I have been researching (Whole Coach) water filtaration systems. I found this on the RV Water Filter Store web site. This may be of interest to you.
"Some RVers may go to parks that are all on untreated wells. The tank is open to the air through the vent and will eventually evaporate the chlorine gas out, anyway. So, to rely on the chlorine residual in water sources to keep stagnation from occurring, may actually increase the chances of developing the very problem trying to be avoided. Nothing beats the periodic need to sanitize the tank. If this is done the way that best suits the RVers use of the tank, then it will not matter if chlorinated water is used and left in, or if that smelly and distasteful chemical is removed through the use of a carbon filter. One thing for sure, if the chlorine from treated water is not removed, then the customer will have to endure the smell and taste from chlorine, sulfur, and other contaminants carbon can remove."
You may want to research this more and determine if your water filters are working.

Gary is correct, the smell that K & E and we have only comes from the bathroom faucet. I have done most of the things that Lucky Mike (thanks for all your sugesstions ) has suggested and we continue to get the smell. As far as the first thing to use in the moring, we use the shower. Even after we both use the shower, we then will use the bathroom sink and still get the smell. After you let the sink water run for a minute the smell seems to go away. We are on city water which is filtered by a house filter system and then have our own filter in-line at the hook-up. I know that we like K & E are stumped. I have even mentioned this to the experts when we had service done and they could not find anything wrong. My next steps are to replace the faucet and then work my way back to the ho****er tank from there replacing water lines if needed.

I think the first sentence of Lucky Mike's Sep 18th post addressed that question. I had the same question but then Mike posted about the bathroom being the first place we head in the am....best explanation I've heard so far. Except for the mechanical vent possibility under the bathroom sink. But then doesn't the gray tank smell differ somewhat from the 'sulpher' smell?

This is way out in left field and may not apply in your situation. Years ago I remodeled a bathroom in the s/b and installed a tub with a shower. Not knowing better I used a galvanized pipe from the tub faucet to the shower head. When copper and galvanized pipe are in contact it causes what is known as dielectric corrosion. The smell from the shower was terrible. After discussing the situation with the plumbers at Home Depot I replaced the galvanized pipe with copper. Naturally the problem went away. I would not expect your RV manufacturer to make the unit using galvanized or copper plumbing but if this is a preowned unit could the previous owner have made the same mistake as I did and used a cheap fix? Like I said - way out in left field.

Waste water from sinks and showers are dumped into your Grey water tank, only the toilet enters into your black tank....both systems have seperate venting and traps and only connect with seperate valves at the end after the holding tanks..... black tank being the larger vavle assembly (3" pipe) and grey water line (1" 1/2 pipe).

Question - does the bathroom sink empty into the black water tank or the grey water tank?
Ours empties into the black water tank and once in a blue moon we get a smell from the drain, NOT THE WATER coming out of the bathroom faucets. We disinfect the drain and clean the trap and good until the next blue moon (months & months).
Just an idea.
RVPAINTER said
07:08 PM Sep 22, 2012
Lucky Mike - our bathroom sink IS emptied into the black water tank NOT the grey water tank. This I verified with the manufacturer. I know as a rule of thumb most bathroom sinks empty into the grey water tank - not ours I'm afraid.
bjoyce said
08:34 PM Sep 22, 2012
Actually it is not uncommon for the bathroom sink to empty into the black tank. Some manufacturers think this is a good idea since many RVers do not put enough liquid into the black tank and many manufacturers make their black tanks larger than needed because many new customers are scared of the black tank so larger makes them feel better.
Lucky Mike said
09:04 PM Sep 22, 2012
by national code these 2 tanks are not to interconnect for health reasons..............you might not mind dirty sink water or bath waters.......but what can be done to ones health from being exsposed to black waste is worse..
this is the reason why you are instructed to dump the black water first then close the valve and dump the grey tank......so the black tank carries less of a chance of moving the fecal waste bacteria into the grey tank and its connections..(all your sinks and fresh water contact areas...
The black tank is is only accessed by the toilet flange and one 1"1/2 direct vent wich must be isolated and carried above the roof line .
RVPAINTER said
10:38 PM Sep 22, 2012
bjoyce hit the nail on the head and this is the reasoning my RV manufacturer said they connect the bathroom sink to discharge into the black water tank. I'll ask them about "national code" - if it's a violation of national code - they should fix it before we leave Elkhart.

How could the water coming out of the bathroom faucet be contaminated from the back water tank?
bjoyce said
05:38 AM Sep 23, 2012
There is no interconnect between the black and grey with the bathroom sink going into the black tank. There are RVs with only one waste tank, no grey tank at all. I guess I am wondering why this is such a big issue since grey tanks are for convenience since in a house with septic it all goes into one tank.
Considering what people put into grey tanks I don't trust that water either. Chemicals, dirt and much more go into the grey tank.

I agree 100% Bill - I don't think there is an issue. Glad to know my rig is not violating any kind of national code. I've never considered the bathroom sink to be potable water even in a home - in general bathrooms are dirty places. We rinse our toothbrushes with bottled water and our mouths with mouth wash. We back flush our black and grey tanks twice after every flush as well.
Love your analogy! :>) LOL

We were at an RV service dealer this week to have our awing repaired. We asked their service guy about the smelly water problem we are having. He felt sure it was the water heater. We don't have the rod in ours, but he said there is a reaction with minerals in the water and the inside of the tank. Even though we are only experiencing the smell in one sink, he said to drain and rinse the water heater. Several of you on this forum suggested the same thing. Kevin is very good about maintaining our 5th wheel, but somehow this water tank maintenance slipped past us. After looking at our manual, it recommended flushing it several times a year with heavy use. Yikes. We've owned this unit for 4 years, 2.5 of which are full time. Our manual recommending flushing with vinegar so we will be doing that this weekend. I'll let you know how it goes. Hopefully, it will cure our smelly water problem. Thanks to all of you for your input!

I asked him about that and he said its because the bathroom sink is closest to the hot water heater. That's actually not true. The shower is closer. He said both hot and cold faucets smell because the water mixes. Since we discovered we should have been flushing our hot water heater regularly, we're going to give it a try. I'm still not completely convinced this is the problem because it only happens in the bathroom sink, but we'll see what happens. Stay tuned :)

K&E,
I am not familiar with your rig, but I can almost guarantee that your rig probably has washer & dryer hook-ups .……and, that you either do not have a washer & dryer, or if you do, that you rarely ever use them. Correct?
I think that you will find that there is very stagnant water standing in the PEX lines that feed to your W/D hook-ups. It will start to back up in the lines to the point where the water flow from an active faucet picks it up and takes the nasty water to the next fixture in use.
This is a fairly common problem for those that have never installed a W/D because the water does not circulate at all in these dead-end lines. The easy solution is to occasionally hook up a water hose to your W/D faucets and flush the lines with fresh water. Try that and see if it remedies the situation. I bet you a beer that this is what you have going on in your rig.
If, after you flush the W/D lines, and this solves your problem, you will want to do a fresh water tank flush with some chlorine bleach (un-scented of course)and use the 12 volt water pump to sanitize all of the water lines in the rig, especially the W/D lines again. Don’t forget to bypass the hot water tank when you do the bleach treatment, so you don’t fill it up with bleach water.
In my case, I decided to access the waterlines behind the basement wall, disconnect and cap off the PEX lines that supply the W/D. That way, I never have to mess with flushing the lines.
Hope this helps. ...Cheers!

My first thought was the hose hooked up to the RV. We had our 5th wheel parked for several months in the desert and used it every couple of weekends.
The freshwater hose was hooked to a two stage filter from the city water source and then connected to the RV. One weekend I ran water into the bowl for our dog and noticed reddish crud floating in the water. The water smelled bad.
I disconnected the hose from the RV and the water that came out was full of this red algae looking stuff. I flushed the hose and everything was back to normal. I guessed the water sitting in the hose cooked in direct sunlight and the reddish stuff formed. Which surprised me since this was a closed system so there shouldn't have been any oxygen to support algae growth.

Thanks, Overlord for your input. So far, since flushing the hot water tank, the smell has not returned. But, what you are saying certainly makes sense. You are correct in your assumption that we have the W/D hookups, but don't have the W/D because we don't want them. If the smell returns, we will definitely follow your suggestions. That would explain why the water doesn't smell at all the sinks, only the bathroom one. It would be closest to the W/D hookups. I'm really surprised none of the RV dealers we talked to knew about this.

I have been amazed at the number of very common issues that RV dealers have "never heard of before", which seem to be fairly well documented on various popular RV forums.
The stagnant water in the W/D lines on my 5er was compounded by the fact that I am using non-chlorinated well water most of the time. Very stinky smell from the bathroom hot & cold faucets!
I think that if you are using water from a municipal source that is chlorinated, that the problem does not rear it's ugly head that often. In my case, I decided to avoid the prospect of it happening again and again by "decommissioning" those two PEX lines, since I will never install a W/D set. The hoses are still there, just disconnected and capped off so there are no long runs of dead-end PEX where water can't circulate.
In any event, it will be very simple to hook them up again if I ever change my mind, or sell the rig.
Just a quick update on the smelly water problem. After consulting this forum and a couple of different service guys at RV dealers, the consensus was that we needed to flush our hot water heater. We didn't understand this because we were only getting the smell at one sink, not the kitchen or shower faucet. However, we did as was suggested. Flushed the hot water heater and sanitized the fresh water tank. Three weeks later the smell is back again, only at the bathroom sink. Therefore, we believe Overlord is on to something. We will now investigate the W/D lines and flush and sanitize those lines. We are currently working at Amazon so when we have time, DW will cap off the W/D line behind the basement wall. Thanks to everyone for their advice.

K & E,
I know this is going to sound strange, but if you have a blender, put some water from the kitchen sink (not the smelly water from the bathroom sink)into the blender. Blend the water to aerate it and then see if you smell the smell. If you get the smell after it has been blended then it is just the smell of the water coming from the spigot. The aeration released the smell. The reason you only smell it from the bathroom sink faucet is because that faucet has an aerator on it and the kitchen & shower do not. The aerator can be removed from the bathroom sink.
This was a suggestion from a tech that we told your situation too.
Who knows if this is your problem, but I would love to know the results.
Lucky Mike said
01:26 AM Oct 23, 2012
Could be back to a water quality issue........Linda is correct that the shower and most kitchen sinks do not have airators on them....remove the screen airator from the bathroom sink and see if it goes away(it just unscrews from where the water comes out of the spout) if the smell goes away or lessens greatly your water is the culprit and this would be the easiest simple test. without dragging the tools out and your favorite coveralls..............might even get to squeeze it in during the commercial !!

First, as mentioned, clean the entire system. We use our TT for extended trips only, one to seven months long and drain all the water everytime we come home, this includes the water heater. I do not blow the water out such as for winter, just open the drains on the tank and water heater, also opening the faucits inside to break the vacuum. Never have a smell doing this and it is so easy and fast.

The quick and easy thing to do to find out if I'm right is to get a bowl or some other container and stick it under the W/D faucets. Open up both faucets (one at a time) slowly, and run some water out into the bowl. It will become immediately obvious to you if the W/D PEX lines are the cause of your problem!

Last weekend Kevin hooked a hose to the faucets for the W/D hookup and we ran the hose to the shower stall. He opened up the W/D hot water faucet first and the smell was awful. Then he opened the cold water faucet. It also smelled, but it had more of a chemical smell. So, we ran bleach through both W/D lines as well as the bathroom sink lines again. The smell is now gone. We'll see how long it takes to come back. I definitely think the W/D lines were the culprit. As soon as Kevin has some time, he will be capping off the W/D lines in the basement area. Thanks to Overlord for this tip. Hopefully, the mystery is solved.

Overlord said
01:32 PM Nov 4, 2012
K&E,
In order to cap off the two lines, you will probably need Flair-it PEX compression fittings. It will, of course, depend on how your rig is plumbed, but most modern RV's use these fittings. You won't know for sure, until you get behind the basement wall and see for yourself.
Most likely, you will need to get two (2) 1/2" caps to do the job. If I recall correctly, I only used one cap to close off an existing Tee fitting after I disconnected one of the W/D feed lines. On the other line, I removed the existing Tee fitting completely and replaced it with a Flair-it 90 degree Elbow fitting just because it made sense for the way it was plumbed.
Like I said, you won't know for sure what fittings you will need until you actually see what kind of plumbing "rats nest" the manufacturer installed in your rig. No two rigs are exactly the same, even though they may have come off of the same production line on the same day! That is just the way it is with the entire RV industry. It makes for a lot of headaches for us consumers.

wouldnt it be easier to get 2 Shark Bite Valves at home Depot or lowes and cut them in at the TEE...........that would keep the washer plumbing intact with a secondary shut off and eliminate the dead water storage area .
this is just my opinion...........but yes, I am a lic. plumber
Overlord said
10:21 PM Nov 4, 2012
1. Well, for one reason: $4 vs $30
2. The cap just screws onto the existing fitting by hand, no tools or cutting of hoses needed. No extra junctions for potential leaks, (although shark bites do seal very well as long as the O.D. of the tubing is smooth, undamaged, and cut off square).
3. It is simple enough process to reconnect the disconnected hoses if you need to. Not that you would need to do so with any regularity.

I want to do a quick update regarding our smelly water problem. I want to thank Overlord very much for the advice regarding the W/D lines causing the smell. We flushed those lines 6 weeks ago and since then no more smell. We had lots of advice regarding tanks, water heater, source of water and none of those solutions kept the smell away for more than 2 or 3 weeks. I think the mystery has finally been solved. My husband will be doing a bypass of the W/D lines since we don't need them as soon as he gets some time.
Thanks again Overlord for your help. It was priceless!!!
Overlord said
01:05 PM Dec 20, 2012
Good news!
Don't forget, it is still a simple matter to hook a garden hose up to the W/D hookups and run it to the shower(or even outside) and re-flush the lines every once in awhile, at least until he gets the by-pass done.
Glad to have been able to help you solve the problem.

I did some research, you need to empty ur fresh water tank, close it, put a cup of bleach mixed in with water in a jug, use a curved looking funnel, turn off your water heater!!!!!!!
put the bleach water in your fresh water tank where the water hose goes into rv, then use your rv pump fill the rest of your fresh water tank with clean water with the drinking hose connnected.
open all your faucets one at a time, cold first, you should smell some bleach.
turn off the faucets, including make sure you use water in the toilet, it let's the bleach water get to all the pipes,
I have the same problem. I'm going to do all this tomorrow.
let the bleach water sit in your pipes and tank for 24 hours.
I live in mine so I won't have water for a day.
take a bath or whatever before doing this.
then, you're going to turn off that pump & open faucets, hold foot on toilet & open those bathroom sink faucets handles, let all the bleach out and refill your tank with clean water, the problem should be gone.
I just googled it and got directions I didn't know and have not used my labarotory in 4 months because of the smell the smell from the toilet fresh water smelt like sulfer or worse rotton eggs.
I guess the people replying to you did not understand it's only the bathroom toilet and sink like mine.

I'm wondering if anyone else has ever experienced the smelly water problem we are having. We have a continuing problem with the sink in our bathroom and smelly water. About once a month the water coming from both faucets starts to smell like sulfer. After doing some internet search, I read that the smell is due to bacteria. It is only the water coming out of the bathroom sink that smells. None of the other faucets or shower ever have the smell. We run bleach through that faucet and it will be good for about a month. Then the smell returns and we do the bleach thing again.
Any ideas or suggestions on why this is happening or how to solve it for good. We are stumped!
Try checking your freshwater tank for discoloration and build up.....altho on most units this should be bypassed when on shore setup you could have a bad checkvalve and it is mixing...
durring my career I have seen so many tanks that people did not know that they needed to be sanitized & cleaned........cleaning on these tanks should be done while the coach is in motion so the sanitizer can swish & clean the tank and depending on the region of water intakes should be done several times a year.......only fill the tank to half capacity when doing it.......This allows the salution to agitate in the tank and loosen most of the scale and buildup....at your destination you just have to flush it twice and away you go!!
I also would sugest doing your waste tanks durring every travel and adding several bags of Ice down the commode to loosen up solids and waste that have accumulated on the tank and sensors.....

I also have the same issue in our Montana and have not been able to figure it out either. Let's hope that some one has had this problem and figured this out. I do know that when I get the smell if I let the water run a little the smell will go away. but if it sits again for awhile it will return again.
Gene....I second that on the mechanical vent under the sink ,I forgot all about it...(guess mine is still working). As far as bacteria build up .....all faucets would have the smell if this was the problem.
I would right off follow genes advice...a mechanical vent is available in some states in home depot and definitly at all rv supplies
I also would clean the trap below the sink......mold buildup in the trap would also cause this problem due to hair and soap scum staying in the trap and causing wicking..
If the smell is a rotten egg smell.....it is sulfer , it is either the water source or again Drain the hot water heater....and clean or change the Calrod. or if you are in a region or just left one that is pulling well water....south eastern or western states....or well water with swamp areas outside of the camp area you are in
of course I could be wrong seeing Im not there to look at it............26 yrs as aLic. Plumber HVAC/R and 20 years doing RV services........simple fix , flush system, sanitize....change water filters ........
free advice goes along way.......
If this method doesnt work , call out a service truck ......he will flush the system ,sanitize....change the filters and gladly charge you a couple hundred bucks!!!!!!
people only question free advice........yet if you charge them they will argue forever how simple it was to do......and show you exactly how long it took you to do it!!!!!

I have to agree with K & E. I don't think it is the trap or the waste tanks. It is actually the water that is coming out of the faucet. Seems to be something that happens if the water sits in the water lines for a few hours or something to do with the faucet.
The strange thing is that the smell only comes from the water in our bathroom sink. We've never had in in the shower or kitchen sink which also use hot water regularly. Same thing with the tanks. If it was a problem with either of those things wouldn't you think it would be happening at all faucets.
This surely has us stumped. Again, thanks for any advice given. We all learn from listening to each other!!
first Draw of standing water after roughly 12 hours of standing and being heated will be the bathroom area(we all head there first).....water from campground and unkown sourcing can contain sulfer and this is frequent within the rv industry , plus water gases when it is heated and creates hydrogen and oxygen....it also creates calcium and other mineral build ups within your tanks and lines..........the easiest method for cleaning the tank without disassembly would be to shut the water off and remove the drain plug completely....do not just open the pet**** valve...
PLEASE MAKE ABSOLUTELY SURE YOU HAVE ALLOWED THE TANK TO COOL......SUGGEST SHUTTING IT OFF AND RUNNING IT UNTIL IT PURGES COLD AT THE FAUCET!!!!!
Once the tank is drained take a garden hose with a spray nozzle on it and spray with force thru drain port hole.....do this several times to loosen up debri in tank and flush it out dthis will get the trash that causes the smell out of the tank.....then go inside remove airater filter from bath room and kitchen faucet. start the water purge from the tub faucet until cleared...then do bath and kitchen......change inhouse filter and you should be good to go
But does that explain the "smelly water" coming ONLY from the bathroom faucet?
If I am understanding the thread correctly, it doesn't stink in the shower nor the kitchen faucet, only the bathroom faucet. It's not the trap, it's the water coming out of that one faucet only.
That's IF I understand the problem correctly.
I don't have the answer since I don't have an RV as of yet but it seems like the subject was getting turned to the tanks. If it was in the fresh water tanks, wouldn't the water coming out of the kitchen faucet or the shower head also stink? If it were the water heater, wouldn't the kitchen and shower water stink? It seems to be only the bathroom faucet.

I'm no expert like many here on this site, but this is exactly what i'm trying to prevent. In my previous post, I have been researching (Whole Coach) water filtaration systems. I found this on the RV Water Filter Store web site. This may be of interest to you.
"Some RVers may go to parks that are all on untreated wells. The tank is open to the air through the vent and will eventually evaporate the chlorine gas out, anyway. So, to rely on the chlorine residual in water sources to keep stagnation from occurring, may actually increase the chances of developing the very problem trying to be avoided. Nothing beats the periodic need to sanitize the tank. If this is done the way that best suits the RVers use of the tank, then it will not matter if chlorinated water is used and left in, or if that smelly and distasteful chemical is removed through the use of a carbon filter. One thing for sure, if the chlorine from treated water is not removed, then the customer will have to endure the smell and taste from chlorine, sulfur, and other contaminants carbon can remove."
You may want to research this more and determine if your water filters are working.
Gary is correct, the smell that K & E and we have only comes from the bathroom faucet. I have done most of the things that Lucky Mike (thanks for all your sugesstions
) has suggested and we continue to get the smell. As far as the first thing to use in the moring, we use the shower. Even after we both use the shower, we then will use the bathroom sink and still get the smell. After you let the sink water run for a minute the smell seems to go away. We are on city water which is filtered by a house filter system and then have our own filter in-line at the hook-up. I know that we like K & E are stumped. I have even mentioned this to the experts when we had service done and they could not find anything wrong. My next steps are to replace the faucet and then work my way back to the ho****er tank from there replacing water lines if needed.
I think the first sentence of Lucky Mike's Sep 18th post addressed that question. I had the same question but then Mike posted about the bathroom being the first place we head in the am....best explanation I've heard so far. Except for the mechanical vent possibility under the bathroom sink. But then doesn't the gray tank smell differ somewhat from the 'sulpher' smell?

Years ago I remodeled a bathroom in the s/b and installed a tub with a shower. Not knowing better I used a galvanized pipe from the tub faucet to the shower head. When copper and galvanized pipe are in contact it causes what is known as dielectric corrosion. The smell from the shower was terrible. After discussing the situation with the plumbers at Home Depot I replaced the galvanized pipe with copper. Naturally the problem went away. I would not expect your RV manufacturer to make the unit using galvanized or copper plumbing but if this is a preowned unit could the previous owner have made the same mistake as I did and used a cheap fix? Like I said - way out in left field.
Waste water from sinks and showers are dumped into your Grey water tank, only the toilet enters into your black tank....both systems have seperate venting and traps and only connect with seperate valves at the end after the holding tanks..... black tank being the larger vavle assembly (3" pipe) and grey water line (1" 1/2 pipe).

Ours empties into the black water tank and once in a blue moon we get a smell from the drain, NOT THE WATER coming out of the bathroom faucets. We disinfect the drain and clean the trap and good until the next blue moon (months & months).
Just an idea.
by national code these 2 tanks are not to interconnect for health reasons..............you might not mind dirty sink water or bath waters.......but what can be done to ones health from being exsposed to black waste is worse..
this is the reason why you are instructed to dump the black water first then close the valve and dump the grey tank......so the black tank carries less of a chance of moving the fecal waste bacteria into the grey tank and its connections..(all your sinks and fresh water contact areas...
The black tank is is only accessed by the toilet flange and one 1"1/2 direct vent wich must be isolated and carried above the roof line .
Considering what people put into grey tanks I don't trust that water either. Chemicals, dirt and much more go into the grey tank.

Love your analogy! :>) LOL
K&E,
I am not familiar with your rig, but I can almost guarantee that your rig probably has washer & dryer hook-ups .……and, that you either do not have a washer & dryer, or if you do, that you rarely ever use them. Correct?
I think that you will find that there is very stagnant water standing in the PEX lines that feed to your W/D hook-ups. It will start to back up in the lines to the point where the water flow from an active faucet picks it up and takes the nasty water to the next fixture in use.
This is a fairly common problem for those that have never installed a W/D because the water does not circulate at all in these dead-end lines. The easy solution is to occasionally hook up a water hose to your W/D faucets and flush the lines with fresh water. Try that and see if it remedies the situation. I bet you a beer that this is what you have going on in your rig.
If, after you flush the W/D lines, and this solves your problem, you will want to do a fresh water tank flush with some chlorine bleach (un-scented of course)and use the 12 volt water pump to sanitize all of the water lines in the rig, especially the W/D lines again. Don’t forget to bypass the hot water tank when you do the bleach treatment, so you don’t fill it up with bleach water.
In my case, I decided to access the waterlines behind the basement wall, disconnect and cap off the PEX lines that supply the W/D. That way, I never have to mess with flushing the lines.
Hope this helps. ...Cheers!

The freshwater hose was hooked to a two stage filter from the city water source and then connected to the RV. One weekend I ran water into the bowl for our dog and noticed reddish crud floating in the water. The water smelled bad.
I disconnected the hose from the RV and the water that came out was full of this red algae looking stuff. I flushed the hose and everything was back to normal. I guessed the water sitting in the hose cooked in direct sunlight and the reddish stuff formed. Which surprised me since this was a closed system so there shouldn't have been any oxygen to support algae growth.
I have been amazed at the number of very common issues that RV dealers have "never heard of before", which seem to be fairly well documented on various popular RV forums.
The stagnant water in the W/D lines on my 5er was compounded by the fact that I am using non-chlorinated well water most of the time. Very stinky smell from the bathroom hot & cold faucets!
I think that if you are using water from a municipal source that is chlorinated, that the problem does not rear it's ugly head that often. In my case, I decided to avoid the prospect of it happening again and again by "decommissioning" those two PEX lines, since I will never install a W/D set. The hoses are still there, just disconnected and capped off so there are no long runs of dead-end PEX where water can't circulate.
In any event, it will be very simple to hook them up again if I ever change my mind, or sell the rig.
Good luck!
At some of the larger rallies you can buy Purogene, which will chlorinate your water tank the same as city water. There are multiple online sellers like http://www.billydump.com/3r/purogeneinfo.htm, http://www.billydump.com/3r/purogeneinfo.htm, and http://www.3rodorcon.com/. I think the people we bought from last at a rally are the 3rodorcon website, who have local dealers listed.
K & E,
I know this is going to sound strange, but if you have a blender, put some water from the kitchen sink (not the smelly water from the bathroom sink)into the blender. Blend the water to aerate it and then see if you smell the smell. If you get the smell after it has been blended then it is just the smell of the water coming from the spigot. The aeration released the smell. The reason you only smell it from the bathroom sink faucet is because that faucet has an aerator on it and the kitchen & shower do not. The aerator can be removed from the bathroom sink.
This was a suggestion from a tech that we told your situation too.
Who knows if this is your problem, but I would love to know the results.
We use our TT for extended trips only, one to seven months long and drain all the water everytime we come home, this includes the water heater. I do not blow the water out such as for winter, just open the drains on the tank and water heater, also opening the faucits inside to break the vacuum.
Never have a smell doing this and it is so easy and fast.

K&E,
In order to cap off the two lines, you will probably need Flair-it PEX compression fittings. It will, of course, depend on how your rig is plumbed, but most modern RV's use these fittings. You won't know for sure, until you get behind the basement wall and see for yourself.
Most likely, you will need to get two (2) 1/2" caps to do the job. If I recall correctly, I only used one cap to close off an existing Tee fitting after I disconnected one of the W/D feed lines. On the other line, I removed the existing Tee fitting completely and replaced it with a Flair-it 90 degree Elbow fitting just because it made sense for the way it was plumbed.
Like I said, you won't know for sure what fittings you will need until you actually see what kind of plumbing "rats nest" the manufacturer installed in your rig. No two rigs are exactly the same, even though they may have come off of the same production line on the same day!
That is just the way it is with the entire RV industry. It makes for a lot of headaches for us consumers.
Since you work for Amazon, this should be right up your alley, although they are sold & shipped from BIC Warehouse. http://www.amazon.com/Flair-It-Central-16860-PEX-Cap/dp/B000H602C8/ref=sr_1_6?ie=UTF8&qid=1351815508&sr=8-6&keywords=flair-it+fittings

wouldnt it be easier to get 2 Shark Bite Valves at home Depot or lowes and cut them in at the TEE...........that would keep the washer plumbing intact with a secondary shut off and eliminate the dead water storage area .
this is just my opinion...........but yes, I am a lic. plumber
1. Well, for one reason: $4 vs $30
2. The cap just screws onto the existing fitting by hand, no tools or cutting of hoses needed. No extra junctions for potential leaks, (although shark bites do seal very well as long as the O.D. of the tubing is smooth, undamaged, and cut off square).
3. It is simple enough process to reconnect the disconnected hoses if you need to. Not that you would need to do so with any regularity.
Thanks again Overlord for your help. It was priceless!!!
Good news!
Don't forget, it is still a simple matter to hook a garden hose up to the W/D hookups and run it to the shower(or even outside) and re-flush the lines every once in awhile, at least until he gets the by-pass done.
Glad to have been able to help you solve the problem.
I did some research, you need to empty ur fresh water tank, close it, put a cup of bleach mixed in with water in a jug, use a curved looking funnel, turn off your water heater!!!!!!!
put the bleach water in your fresh water tank where the water hose goes into rv, then use your rv pump fill the rest of your fresh water tank with clean water with the drinking hose connnected.
open all your faucets one at a time, cold first, you should smell some bleach.
turn off the faucets, including make sure you use water in the toilet, it let's the bleach water get to all the pipes,
I have the same problem. I'm going to do all this tomorrow.
let the bleach water sit in your pipes and tank for 24 hours.
I live in mine so I won't have water for a day.
take a bath or whatever before doing this.
then, you're going to turn off that pump & open faucets, hold foot on toilet & open those bathroom sink faucets handles, let all the bleach out and refill your tank with clean water, the problem should be gone.
I just googled it and got directions I didn't know and have not used my labarotory in 4 months because of the smell the smell from the toilet fresh water smelt like sulfer or worse rotton eggs.
I guess the people replying to you did not understand it's only the bathroom toilet and sink like mine.
best of luck
