Water pump

After 6 months in Arizona, arrived home end of March in Canada. Drained and winterized after getting home. Today I filled the fresh water tank and turned on the pump to fill the hot water tank. Now the pump won’t shut off. I left it off for a hour so but when I turn it back on it still runs. No leaks anywhere. Any ideas ?

It means something is open somewhere. Would help to know what type of RV as water inlets differ.

Check your water inlet fill cap on tight and check the screen inside. Check valves can get worn out or just pushed out of position. Push it with your finger to reseat and try again.

. 2011 Rockwood TT. Fill cap is on and I never touched any valves when I got home. Is there a reset on the pump ?

when you open a tap does water come out?

Yes.

Yes. I put the hot water tank on gas and when it reached temp and shut down I released the check valve for relief in the tank. Same thing, turned on the pump and it keeps running.

There may have been some water left in the pump that froze and changed the pressure switch adjustment. Check your pump manual for the correct adjusting procedure.

How long has it been running? First thing it does is fill the water heater if it is not bypassed.

Hi,

Sounds like a torn membrane in the pump.

CITY WATER FILL 'pump' bypass valve ??

our safari had that, had to be open to fill the water, and closed to use the pump

You said you "filled the tank". Do you have a tank fill valve by your city water hose inlet (not talking about the gravity fill port for the fresh water tank, but where you connect the hose for city water use in the RV)? If that fill valve is left in the fill position (instead of "city water pressure to the coach" position), the pump will just be circulating water back to the tank nonstop.
