Fresh/city water question

Question for the tech guys. On out last trip had water leaking out fresh water tank vent in the water station where cutoff valve is. Checked fresh water and sure enough was full and over flowing. Drained off fresh water tank till empty and worked lever from Fresh to City position a few times. With valve in City position water was leaking out slightly from fresh tank with drain open. Left water on all night with drain open so as not to overfill tank. Next morning no water was coming from tank drain and all seems to be working correctly. Do I have a problem that will resurface or just a glitch, maybe something got flushed out. Trailer is still under warranty but don't want to waste everybody's time with "no problem found".

If you have Anderson four way valve in your water compartment it is prone to having a seal roll and this will let water bypass into fresh water tank

If you have single lever for city water selection then Id suspect the check valve on the water pump has some junk in it. If so this will stick open and allow water to backfill fresh water tank

Are you using a quality regulator on the city water line? My understanding is those valves are very prone to damage from high pressure.

Just info for any newbies onboard!
This is NOT a regulator, it restricts the flow to reduce the pressure regardless of what pressure the faucet has.

This is an adjustable regulator, doe not restrict the the flow & If the faucet pressure is above the preset pressure will regulate the pressure down, if below the preset it will not affect the flow.

I don't know for sure which valve I have. My lever points to city or tank fill for same connection. From your comment I suspect I had junk in the check valve at water pump.

Mine has done this since day one. It sounds like I have the same valve that the OP has. We live in our trailer full time so I didn't take it back to get it fixed. My (temporary) solution has been to use the water pump when taking showers to pump the tank down a bit so it doesn't overflow out of the vent line.

Permanent solution will require taking the chloroplast off to attempt a permanent repair...I'm inherently lazy...temporary solution has been working just fine!

I doubt you have to pull the chloroplast, If you have a Anderson Valve it will be identified on the plastic surround. Google it and instructions will detail the disassembly and repair kit. If it is the check valve on the water pump most are accessible from inside.

^^^^On my trailer the water connections are in the left rear corner. I have found ZERO access to that corner, inside nor outside. On the inside I have a built in "end table" with no obvious access panel. I considered removing the entire "faceplate" from the outside of the trailer to look at it, swap the valve out. etc. Just haven't gotten around to doing anything about it (refer back to inherently lazy).
