YES..the pump only draws from the fresh water tank.
If it is ON while connected to city water..it won't run unless city water pressure drops low enough for pump pressure switch to start pump (typically 30# for standard pump..45# for higher pressure pumps)
So if you are showering the pump may come on and help
