Fresh water leak

I have a 2017 Classic. Yesterday, while on city water, I noticed water dripping out of bottom seams along the side of the trailer, going from the wheel well back to the water cabinet. I opened the fresh water fill door and water was coming out of the fresh water fill vent. I am assuming the check valve on the fresh water had some debris or had not seated and allowed city water to back flow into the fresh water tank. Iíve had this happen on other units in the past and solved it by running the pump for a few minutes. For now, this seems to have resolved the issue.

My question and concern is how did the water get behind the fresh water fill compartment and into the underbelly? Could there be a fitting leak on the fresh water fill piping? If you have seen this before and know likely cause, then I would appreciate your feedback. Iím not so worried about the tank filling on city water, unless it didnít resolve itself. But I am worried about how the water got behind the wall.

For how long would you say this might have been taking place? Minutes or hours for instance?

Water forced up from the water tank, and overflowing the fill vent, has to find some way out. Assuming the water fill exterior door was closed and locked, gravity would have sucked the overflowing water downward, and the water found its way through every little crack, nook and cranny available IMO, all inside the exterior aluminum skin. Sooner or later, the water HAD to drip out somewhere.

Good thing you found the problem when you did, and that you know about turning the pump on/off etc. to clear the check valve. Hopefully that will solve things.

Good luck,

Peter

To quickly test for your plumbing system is to disconnect from city water and turn on your water pump. If it won't stop running or cycles frequently then you have a leak.

Parallel threads. Easier to stick to this one IMO.

Pressure test is good and water pump doesnít cycle. It definitely came from the water overflow. Just couldnít see where it was getting behind panel.

The fill tube or overflow tube from the fresh water tank may not be clamped tightly allowing leak out of the tank.

Did you read Post #2? Seems like a possible route, perhaps the only one IMO.

Thanks for the update.

Our 2016 30 Classic has the fresh water tank problem when the tank is full and we are hooked to city water. We notice not only water coming out at the tank fill area but also on the floor behind the toilet.

Iíd really like to believe that running the pump is all I need to do.

Our 2017 Classic did the same. Bad check valve in the pump, we seldom use the water pump. Replaced pump under warranty, all is good.

Seems like I remember a small vent inside that fill door covered with a screen. Perhaps, a vacuum breaker vent for those who stuff a hose in the fill connection. Must come from the full hose, and might add to post #2 suspicion.

The vent is connected to the top of the tank separately. Itís to let air in and out of the tank as the level changes.

Hello, having a similar issue. With the city water off it appears the leak stops. I have a leak coming from just forward of the exterior city water hookup that exit's by the hookup. I removed the white hookup box and the lines look dry however where they penetrate the floor going up that flooring is wet. My water pump location is dry and the top of the lines in the bathroom are dry. I cannot see how to remove the bathroom cabinet under the sink so I can investigate there. I opened my city water connection cabinet and it is dry there. Pump cycles like it should. Any ideas?
