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. .
Some campers put a check valve on the Out going pipe from the water pump and before the connection to the incoming city water line, which also has a check valve to keep the water pump from spilling out the city fill.
Other campers depend upon the water pump to keep from back-feeding into the fresh water tank. Check the connection, right at the pump (out going side), see if there is a check valve there, or maybe at the connection point where city and pump (incoming) lines come together.... sometimes, in older campers, there was a check valve there.
