Help please! Today my city water inlet Has decided to fill and overflow my fresh water holding tank??? Haven't changed anything it's did it on its on. What do I do to fix this? CJ
Two possible causes. (Well 2.2 One (Diverter valve) covered the point 2 is also this valve but you bumped the handle and it's mid-position.
The other suspect is the check valves on the water pump.
Beyond that there are no additional suspects unless you have some fancy things like a "Suck out of a bucket to fill the tank" system in which case those vavles are also suspect,, such are usually after-market add ons. .
