Re: Water running out kitchen facet when off and hooked to city water
Hi diesel_doberman,
You didn't quite say, but it sounds like maybe you've been dry camping and the faucet works ok when using the water pump/fresh water tank. If that's the case, I'd ask if you have a water pressure regulator installed. If the campground water pressure is too high, it might be overwhelming the faucet, and other parts of the plumbing system. The Heartland manual warns to not let city water pressure get over 60psi. Most people set theirs to 40 or 50psi or use a non-adjustable regulator which is usually set to 40psi.
If you do have a pressure regulator, or if the same problem happens when the pump is ON, then you'll have to either replace the faucet or take it apart and replace whatever part has failed. Same as if it happened in your house.
