Hot Water Heater Leak

Hey everyone,


Well on our latest trip out over the weekend the hot water tank sprung a small but noticeable leak. I have it traced down to the top connection on the back side of the tank. Which i believe to be the hot water out side. I already tried tightening it and i feel like if i go tighter it will break the plastic connection. Also the other weird thing is it only leaks when the water heater is on and very hot. It stops leaking within 5 minutes of shutting it down. It's not a huge leak but enough for my wife to find a water puddle under the kitchen cabinet when she was getting a pan out.


So my question is this, should i take the fitting off and wrap some Teflon thread tape around the connection and hope that fixes the leak? Or should i replace the connection. The reason I ask is I remember somebody on here saying that thread tape on this plastic plumbing makes things worse. Any ideas would be appreciated. We are heading out again tomorrow and i would love to have this resolved by then. Thanks

I have had that same leak and removing the valve and adding more Teflon tape fixed it. I am sure it is a combo of movement and heat that causes those connections to loosen a little.

We had the same leak as well on a few rigs. One, changed the fittings to brass with teflon, other one did as norty1 did. No problem.

My 2012 eagle t/t has the same leak. So far, I have an alum pie pan setting underneath. Have been thinking of a sure way to fix. I think the pic clamp has loosened, and I refuse to buy a pic tool. Prob will try the brass fitting.

Thanks for all the input, I was able to get to it and put some more thread tape on the fitting. Looks like all is good so far.

Water under pressure will find any way to leak, and I've always found that at least two wraps of Teflon tape on threaded fittings is a must.
