  • Fresh water tank drain valve

    Posted by Brady on January 1, 2019 at 7:24 pm

    Seemed to have developed a drip leak from the fresh water tank dump valve. Any suggestions other than pulling the valve and replacing the seals? It has been suggested that Thetford makes a sealer liquid assume I swells the seals. I question whether this is safe to use in the fresh water tank?

    suggestions appreciated…

    thanks,

    As easy as it is to replace. When mine started leaking, I just drained the tank and put the new one in and refilled the tank. Took about an hour and the valve is cheap. Pick one up at about any RV store. You’ll need a tube of silicone also, to seal the opening around the PVC elbow and the floor…
