City water filling fresh tank
Arg!! This is a new problem. Why is my tank being filled (slowly) by the city hookup? I find water stains (big ones) on the underside of the coach, under the water tank.

or , that check valve is bad. Unhooking the old pump, somehow, you disturbed the check valve. .
Check Valve is a diaphragm inside pump.....not an external one.
That tiny 'burruup' is due to backflow thru pump check valve allowing system pressure to decrease enough to trigger pump pressure switch.
Using pump/more flow thru it may clean up check valve and stop the leaking
