Fresh water tank is filling mysteriously

Our fresh water tank is (mysteriously to us) filling up when hooked up to city water. It never did this before. Is there a switch somewhere? We were parked and hooked up for 6 months, this never happened. Now after traveling for 4 days, suddenly our tank is filling in expectedly.

Yeah lots of threads on this, it comes up once a week here I bet. After reading the thread if you still have questions, fire away.

In addition to the thread already linked in Post #2, you could look in some other spots too. Your check valve at the pump may be stuck open, because of grit that came from the water tank.

Good luck,

Peter

You may have dirty water in the water tank, so drain that, and fill with fresh city water, using a new potable water hose, and an inline filter:

https://www.amazon.com/Camco-10ft-Pr...NsaWNrPXRydWU=

Always use that kind of hose and filter both for filling the tank, as well as for hooking up to city water.

After you have good water in the tank, turn the pump on and bleed all air from all the hot and cold faucets etc., including the outside shower and toilet. Then turn the pump on and off in rapid succession, in hopes of dislodging any grit caught in that previously referenced check valve. Very often this will solve your problem. If not a new pump may be in order.
. . .
PS -- When it is time to turn the pump on/off in rapid succession, make sure you have a faucet open, so that any grit in the pump's check valve can move downstream. That grit may next get caught in a faucet spout aerator, so clean them out too.

PS2 -- You should also clean out the pre-filter at the pump, location per your owner's manual.

Thanks for your response! We seemed to have sorted it out. We shut off the city water and ran the pump for a couple of days to use the water up. We tried turning the water back on. 24 hours later, no water in the tank! I think simply running the pump cleared what ever was clogging it.

Glad you fixed the problem. I was wondering, though … if the filling is mysterious, maybe the content of the tank would be something magical. Gold? Rubies? Bitcoin? Angel's Envy bourbon?
