Water Pump Keeps Running

Figured it out and feel pretty dumb. I relocated the city water connection to the back of the RV for ease of connecting and when I first changed the pump it was hooked up (but house hose off). Today I had unhooked the hose and it was spraying water back out my new hookup. I'm now assuming there must be an anti-backflow valve at the stock city water connection.

The odd thing is the old pump was doing the same thing long before I moved my city water hookup (this is why I swapped the pump). Anyway, all is well.... for now. Thanks for the replies everyone.

One of the items in my post

City Water inlet has a check valve to prevent back flow from RV into City Water System when using the pump
Pump has an internal check valve to prevent back flow thru pump when using city water

I think that's because people don't want to admit to feeling dumb.... I'm so used to it that it's like second nature :)

Could be, but we all learn from mistakes!

Lets see---pump used to just run a minute to hit pressure then shut off, then it seemed to run longer and longer. I finally detected a very small leak, drip, at the pump housing, fixed that, same problem. Took pump apart cleaned it up, saw nothing wrong and put it back in. Now still running forever and low water pressure. I bought a new pump, $87 on Amazon, installed it now have good pressure, and it might run a minute and shuts off. I had cleaned the filter the first time I had it apart but that is yearly maintenance. Just finished this a week ago and don't know if it helps you but there it is

Pump running continuously:
*How do you fill your fresh water tank----FILL valve or Gravity Port
Fill Valve---leaking thru so pump round-robins and can't build pressure
*LEAK...wrap TP around fittings then check in an hour. Wet TP---LEAK
*Pump Check Valve leaking by....new pump should have cured that issue
*Bad Pump Pressure switch----New pump should have cured that issue (switch is on head of pump...give it a whack with handle of screw driver)
*City Water Inlet Check Valve leaking...check for drippings from connection
*Water heater T&P Weeping

Or you have a leak in the line somewhere, sucking air.

May not be the same issue, but we had that on a trip two years ago. Hubby found the problem was a clogged filter leading to the pump. He took it out, cleaned it, replaced it and it works.
