Tank full

I'm sort of new to the forum so forgive me if this question has been answered before. I have been in this resort for about two months and just noticed that my fresh water tank is over flowing. This tank was empty when we first arrived. Can my city water valve be leaking. Thanks ahead for any thoughts.

Most likely it's the check valve on your water pump.

Happened to me too. Yes, water pump check valve. Use it a few times and it starts "checking."

Agreed. Fresh water pump check value failure - when it fails allows city water under pressure to back flow into the fresh water tank.

Not sure who advised us on the same issue. They said it can often result from high water pressure from site overwhelming check valve. Suggested disconnecting from water supply, running only from internal supply on pump until almost depleted. Then, resume hookup from site. Worked for us and did not require replacing check valve.

Ditto on the pump's check valve.

If you are not careful to always use a filter on the hose [both for city water and filling the tank] grit from the water supply can compromise the operation of the valve.

Try turning the pump on and off lots of times, and pressurize the system with city water on and off a bunch of times. Often the problem will go away. If you have time, drain the fresh water tank and monitor the last gallon or two for grit. Use a filter like this one when you fill the tank:

Good luck,
