Ok, start off info : 2016 Fuzion 5er FZ420. We full time live for now at same spot. We are hooked up to City / Park water and I have a regulator with gauge at spickot. We have the system that has the Power Fill switch in the connection hatch door to fill tanks while on City hookup. We also have a separate small door with a Gravity Feed and Overfill tube.
The fresh tank I have used here and there during outages. We typically kept it full which is how it was when we took delivery. I did drain it down some once with the quick dump underneath the coach. But otherwise we are always on city water.
Last night I got home from work (12:30am) and took the pup for a walk. When I returned, I noticed a dripping sound. I guess I didn't think about it when I got home since the AC was on and the roof drip was also going on. I looked under the coach and it was a small lake. We are on a solid pad. I traced the source to the small door used for gravity feed and overflow tube. The stream was steady. I guess about an hour.
I messed with the Power Fill switch and got it to start pouring out. Even with that on the actual Gravity tube started to dribble as well. So I was sure that Power Fill works. Put back to normal and checked my heater and pump switches inside. I opened the dump underneath and let some drain out. But my inside level gauge panel still read full. Those never worked right anyways.
This morning, which for me is 11:30am I woke and checked it. Again it was dripping out the overfill tube and I had a small lake.
I dumped alot more water for the time being to get it to stop. And started my research. I find most issues I see posted are not in relation to a coach with the Power Fill.
But one thing I did try... I cycled the Power Fill switch a few times. I turned off the City water supply. And released the line pressure. I cycles the Power Fill switch again basically a day fire. Then returned to City water pressure on.
Since I previously dumped a good amount of water inside the tank, I won't know until later if I fixed it. Hoping the valve had debris or just sticks.
If anyone has any info, experience, input, ideas....please assist
I have to pull apart the understorage walls to see back there tomorrow. Hope if anything it's valve not pump. But there is a local place here that stocks alot of parts.
