It seems that my black tank shut-off (slide valve) is leaking by, allowing liquid to drain with valve closed ( pull handle not going in all the way either ). May have something logged in the seat. Is there a way to flush up through the drain line to clean it ? Already filled and dumped the tank several times but it may still be leaking by.

Replace the valves. They will tell you it is a 15 minute job. Ours took hours because of position in the wet bay, but can be done.

You can buy a back flush valve like this, http://www.walmart.com/ip/7964401?wmlspartner=wlpa&adid=22222222227009508143&wl0=&wl1=g&wl2=c&wl3=40839951752&wl4=&wl5=pla&wl6=78653592992&veh=sem . With this you can back flush the line and then try filling the tank to 2/3 with water and a mix of 1 cup Dawn dish soap, one cup Calgon water softener and drive the rig around for 30 - 60 minutes to wash the inside of the tank. Then when dumping push the valve in and pull it out several times until it moves freely. This might possible dislodge whatever is stuck and it will definitely lube the seal and blade.

Thanks all for the replies. Will try one or two if the situation continues.
