My hot water heater builds water pressure in my water lines when it is on. Anyone have this problem and how did you fix it. Not easy way to gage but it gets high enough to be noticed when you turn water on. Have pressure regulator on incoming water but builds inside camper not back to faucet. Assume one way valve is holding but can not adjust temp on my water heater,
Any ideas Thanks

You may have a defective or stuck pressure relief valve on the water heater. You might try physically releasing it a couple of times with the lever on the valve. It may have become frozen. Be careful of the blow off coming out of the valve. It will be hot. Hope this helps.

Yes, check your setting on the heater. Sounds like you have it set too high. Most heaters are set at the factory and you will not be able to adust. Look in your manual and it should tell you what the factory heat setting is. If you have a thermometer run the hot water over it and see what it reads. Should be what the manufacturer has it set at. If it reads much higher then you need to take it to your dealer and have them check it. This will cause a pressure build up. Ray is correct check the pop-off and see if it is stuck. Like he said be real careful because that water will come out quickly and it can burn you.
