    Water coming from faucets when pump is off and not hooked to City water??

    Anyone have any idea why, when we are not hooked to city water and pump turned off, we are getting water coming from the faucets??? Not just a trickle either...it's coming out like we're on city water....

    It may be holding pressure from your previous hok up however it should end after a short while.I can think of no other reason for your water pressure.

    You didn't happen to put shut off valves on your tank vents did you ??

    Turn the pump on and let it run for 90 seconds to reduce 5 gallons from the fresh tank. That would remove any pressurization starting in the fresh tank.

    As Jerrod suggested, you probably have a 4-way Anderson Valve which means there should be 2 overflow drains on the fresh tank. If blocked, and at your last stop you had water flowing into the tank, it might have overfilled and expanded.

    Another possibility, although remote, is something squeezing the fresh tank.

    Could the fact the tank is almost empty cause this pressurization?

    I think there would have to be something causing pressure buildup in the tank that would normally be removed through the overflows. So 1) something causing a pressure buildup and 2) something preventing relief through the overflows.

    Silly question but are you really certain you're not hooked up to city water?

    Do you have mud in the vent pipes

    I don't think so...but will check tomorrow. Possibly bug infestation, we've been parked for quite a while...but not sure both could be blocked by bugs.

    If you turn on the faucet does the pressure release and go away ?
