Water Heater Leaking

[Vader]

new issue this weekend - waterheater is leaking from the blow off valve - it's like it won't close but the pull tab is pushed in all the way....... any suggestions, It'll leak from high volumes of water to a drip & then nothing, there seems to be no ryme or reason for it. But it's beginning to pmo.......

Any help greatly appreciated

Our old Cruiser started doing that where it would start out leaking pretty good then go to nothing as the water heated up. I finally replaced the pop off valve which fixed it.

Sounds like the valve is going bad. Easy to replace. Just go to Lowe's, Home Depot or any hardware store and pick up a standard pop off valve. Turn the heater off and let it cool, then unscrew the old valve and screw in the new one.

that makes me feel better, guess i'm gonna go out & drain the tank & then try that, glad I posted, this is hopefully gonna save me some moooonnnneeeeyyyy......

Before you change valve shut of water to camper and open pressure relief valve and allow water to drain out intill it stops running. This gives you a new head of air in tank and should take care of problem.

A lot of people use this valve to drain tank for winterizing and this causes the problem. They are made as a safety feature so if tank overheats it will release pressure and not blow tank up. If used too often the spring safety valve looses tension and will leak. Just replace the valve after you have made sure the temp. is '0' and open all hot taps in unit to bleed off any pressure. Install with teflon tape and should be good to go.
