Where the city water connection is there is a valve in that connection that once the city water supply is disconnected it prevents the water in the rig from draining out. I have had that valve stick and yes you should see water coming out of that connection if bad. Connecting a city water source would exercise that valve.

We have just had a recent post similar to this and member after a while concluded it was the pump and replaced it. Before I would do that I would check all other places for a leak
