There is a check valve in the city water hook-up. It is a spring loaded valve, and is probably hung up partly open allowing the pump water to escape the city water hook up. You may try hooking the city water back up and turning it on to see if the valve will reseal. It can be removed from the MH and taken apart and manually resealed. A Phillips screwdriver may also be inserted into the city inlet, and reseated, as the disk is canted.

X 2 on the inlet check valve. It's a very simple part. You may even be able to coax it into working again.

Thanks for the info. I hope it's that simple. I had no idea there's a check valve. Thanks again for sharing.

Water problem fixed. The washer screen was in backwards depressing the backflow valve. Thanks for the heads up. I hope I can return the favor sometime. Good day.

My check valve hangs up periodically and does what you are experiencing. I can usually reset it with a screw driver as suggested. However, to prevent that annoyance I put a threaded plastic plug in my city hook-up to prevent it from happening when not hooked up to city water.

If reseating the check valve doesn't work, the quick fix is to pickup an in-line hose shut off valve at Walmart or a hardware store and screw it into the city water connection. A screw in hose plug will also work. The permanent fix of course, would be to replace the city water port. They're not expensive, and replacement is a relatively easy DIY job.

tex, glad you got the problem found and fixed. What Dutch said is a great idea, as I have at least 1 spare at all times as the shutoff valves are very handy when connecting to shore hookups.
