Help! Water leak

Originally posted by richardd Help! I found a water leak on the floor of my 2016 R-pod 171. I was hooked up to a house hose. I've never used the fill tank but I took the drain plug cap off and a lot of water came out. Turned the water back on and that worked. Maybe the previous owner had left water in the tank. So I left the plug cap off and overnight it's still dripping slowly. Is that normal? Or is the shoreline hookup leaking somehow into the tank? I don't where to look for a possible leak.

Multiple possibilities, but it is likely that the water in the tank comes through the check valve in the pump. Sometimes, a bit of something gets stuck in it and it allows water from the city water connection to flow into the tank. Now, a slow drip could be that the bottom of the tank is flattening out as the water pressure is no longer pushing it down. It can drip for quite a while.

Thanks Rosie, I see you're in beautiful Bend, Or. I've never been, but my Dad used to say it was the most beautiful place he ever saw. Thanks for the tip. I'll give it a try. Happy Easter!

Our 2016 178 has 1/2" NPT plug on the fresh water tank drain.  I suspect if the tank did not have water in it when you bought it it could be a stuck check valve in the water pump.  This will cause the fresh water tank to fill when hooked up to city water.  Potential cure is to cycle the pump several times to basically reseat the check valve in the pump. This should stop the fresh water tank from adding water when connected to city water.  On a side note, our low point drains also have 1/2" NPT plugs, not straight thread that would require an oring. 

I think you misunderstand me. My low point drain cap(on the fresh water tank) doesn't have an o-ring or rubber washer. It's just a screw on cap. But that's not the problem. With the cap removed, the leak is coming out of the water tank where it was removed.

The leak was small, on the opposide side of the shower. It's not the shower. It was just under the drawers. When I drained the fresh water tank it went away.I think the tank was full. I had never used it, thinking the city water hose connection bypassed it. But the previous owners could have left water in it. I left the cap off the fresh water tank low drain and it's barely leaking, only out of the low drain on the water tank. Only a drop every couple seconds. I don't know if that is normal or not, but it is something I can live with if I have to because it's not leaking elsewhere. I have a water pressure regulator, and have ordered the kind with the adjustible gauge. The hot water tank area is dry.

Thanks for responding, have a blessed Easter!
