Fresh Water System

I have an issue with my fresh water system and am looking for suggestions. Like most units, we have a lever which changes our system from "fill tank" to "city water". IOW, with the lever flipped one way, we are operating on water from the city system through a hose. When flipped the other way, we are filling the tank.

I think there is a leak somewhere in all that. We are currently stopped at an RV park with a water supply. I've been hooked up to water for about a week now. I noticed the other day that my fresh water tank is now showing "full". It was less than half when we hooked up. Later in the day day, I noticed some dripping out of the overflow tube. I dumped a few gallons out of the tank and no more leak.

My suspicion is that the valve is not operating properly and is allowing the pressurized water from the campground to gradually pass the valve and fill up the tank.

Anyone with similar problems, thoughts or suggestions? thanks

Could be the water pump check valve leaking by allowing water to flow backwards through the pump into the tank.

Agree, very likely check valve. We had a similar experience with overflow on fresh water tank when connected to city water. I shut off city water, switched back to running the pump for a day, then refilled the fresh water tank with city water, switched back to city water, and waited. The overflow drain did not leak over the following week. In fact, over the last year we have never had a repeat of the issue. In our case, I suspect the pump check valve may not have fully seated due to small debris in the line that was subsequently flushed when cycling between the pump and city water. That said, others in this forum have spoke about needing to replace their check valve to resolve overflow line leaks caused by water back flow through the check valve, pump and inadvertently overfilling the fresh water tank when using city water.

On 2 occasions my tank overflowed on fill, even though I put the selector handle to where the decal indicated it should be for city water. It actually wasn't completely closing the tank off. I ignored the decal and pushed the valve as far as it would go, that fixed the problem.

Personally I never leave the pressure on the supply hose. I will fill my tank and then use water from the tank.

thank you all for suggestions. I just replaced the pump with a brand new one, before the problem started. Where is the check valve you're referring to?
I'll try cycling the valve handle a few times and also trying to make certain that off is "off"

thanks again

The check valve is internal of the pump. If resetting the valve doesn't stop the tank filling try what ChrisKW suggested. Could be a small piece of debris in the check valve.

Ditto... Make sure lever is turned completely.

Same thing happen to me when I replaced my pump. System would not hold pressure when pump was turned off. I have a 2 1/2 gal accumulator would leak down. By watching the supply line to the pump I saw the water going back in the tank. So I bought a check valve from Home Depot and installed it between the pump and screen filter. Don't install it before screen and tank because it will leak 😗
Works great holds pressure forever.

Back to the original problem, our MH will do the same if the park water pressure is high (above 60ish PSI)...

Not sure what happened, but I fussed around a little; open and shut the valve multiple times, took the handle off the valve and manually operated the valve, turned in three circles with the tip of my index finger touching the end of my nose and presto....something worked. Left the park water on all night and no change in the tank level.
Thank you all for your suggestions as one of them must have worked. I'm pretty sure the turning in a circle thing had nothing to do with it.
