Noticed when we returned from shoping , water running out of the bottom of the trailer. Turned off water supply and unloaded cargo area and pulled panel off to get to the water connections. After getting to the connections found the hot water line leaking from where it comes out of the hot water tank. The leak was where the plastic pipe goes into the tank. It appears as if that end of the plastic has plumers putty holding it into the tank,can't tell if it is threaded or not. Temporary fix "tub&tile caulk. Looking for perminent f fix. Also the drain plug looks as if it is rusted in any suggestions on this?
