HELP! Water leaking from full cap

[Brakeman48]

2016 Hurricane 35C. I have pressure regulator on hose connection. Hooked up at Jellystone in Luray, VA. All faucets work fine. 12 hours later water coming out the Fill cap for the fresh water tank. Never had this issue before camping hooked to water supply.
Any suggestions why this would happen???

Bad washer or cracked cap? You have a pressure regulator, does it show what pressure is in the line or is it of the kind that has no gauge?

There is a check valve in the fill connection. Mine went bad and the same thing happened. Here is a link to sample part on Amazon. This is to give you an idea what I am talking about. There are several different versions and models.

Like mentioned in your other post: It is most likely a valve on your water pump not closing properly. Solution is to turn off city water and run the pump with an open faucet for a few. If there are debris in the pump it should be cleaned out.
