Great job thank you.
Rv check valve problem.
For those just entering the rv lifestyle there is a check valve behind your city water hook up.
Go whole hog and replace the pump itself.
Check for a rebuild kit for the water pump and find out if the internal check valve is a user serviceable part some art some are not.
Second check to see if you left the drain open when filling up the water tank.
The pump check valve may be stuck.
Inside is a plastic check valve plunger a spring retaining clip and small rubber o ring.
Check amazon or rv water filter store for options.
With some of the other issues above you may need to replace parts such as the belt impeller screen to the in line filter element pump wiring etc.

The fix is easy and you can probably do it yourself.
The problem was a bad check valve on the water pump.
Add your own 1 way check valve to the water line on the inlet side of the pump.
When this little known part fails it allows water to flow backward through the pump into the freshwater tank anytime you re hooked up to city water.
There are several things you need to check to ensure your water pump is working again.

I had a problem finding these check valves for my rv water heater locally.
The valve is designed to let pressured city water enter the rv s plumbing system when hooked to a charged hose bib via your water hose in an rv park and prevent the water pump from pumping water out of your potable water tank onto the ground when not hooked to a charged hose bib.
Winterized the rv water pump last year and i can t get to work this year.
First check to see if the shut off valves are open.
