Replacing black/gray tank adapters
I'm replacing the two gray and black water tank adapters since they started to crack and leak. The remainder (valves and pipes) are still in good working order. I ordered the two tank adapters from Inland RV and they should arrive some time today. I also ordered two Thetford valve rebuild kits since I needed new O-rings that go between the valve body and the adapters. I also figured this would be a good time to rebuild the valves even though they didn't leak. One question though. What type of sealant should I use on the tank outlets where the adapters go in. I've thought of silicone glue/sealant and I also have some Dicor self leveling lap sealant. Any suggestions on what I should use?
