One of 2 things.......
The valve on water panel can be leaking thru to the 'fill' position and going directly to tank
OR
the pump internal check valve can be leaking thru.
Install a 1/2" in line check valve on pump discharge.....tank stops filling. Problem solved. (Most any RV parts Store will have one)
Tank still filling....then replace the tank/city water valve on panel
why not just plug off the pump out/house in water line and see what happen
Two different lines...........more hassles. Access.
how are they two different lines? one goes in the pump from the water tank and the other lines goes out the other end of the pump
pretty simple in my mind? my water pump is laying right there in the wet bay
You asked about "pump out/house in" (that would be pump discharge & city water in------two different lines)
Now you're talking about pump suction & pump discharge.
OP has a line that goes from water panel to fresh water tank (FILL) and a city water line (Goes to RV plumbing system......ties into pump discharge) controlled by a diverting valve PLUS the pump discharge line.
Installing a check valve in pump discharge is a way to see if pump internal check valve is leaking back into fresh water tank and if it is then the in-line check valve solves the problem. Simple easy check.
Disconnecting/plugging off other lines can also work.
Simply a suggestion for OP.
You're more than welcome to do it any which way you can come up with.
