Why is my freshwater tank filling up?
When the city water pressure feeds fresh water into the on-board fresh water tank it means one of two things: either a “quick fill” valve is left open (or is faulty), or the check valve in the outlet side of the water pump has failed. In most cases, this check valve is integral to the pump.
How do you get air out of water lines in a trailer?
Most of the time you can simply purge the lines by opening the farthest faucet until a solid stream comes out and work your way back. If the spitting is just happening with hot water, then you have air bubbles in the water heater and should relieve the pressure valve and purge the water again.

Can a pump be used in a fresh water tank?

Is there a manual shut off valve on a fresh water tank?
I have a manual shut off valve between my water pump inlet and the fresh water tank. To eliminate the water pump check valve, I closed the manual valve and the fresh water tank was still filling. In fact, I could hear the water trickling into the tank with the Swan valve against the stop in the city water position.
