Could you let us know the make/model of that pump? I'm courious about this allen screw adjustment RJsfishin spoke of.
I have a Shureflow pump in my 93 Pace arrow. I believe it's original. It has a screen on the intake side that should be cleaned ocasionally. I did have to replace a coule parts but it's still going strong.
The backside of the citywater connection has a check valve and could possibly start leaking. It's nice to have a male plug that can be screwed on that city water connector to keep it from leaking.
If your pump keeps running it's either;
Bad vales on pump.
Bad check-valve on city water connector.
Hot water heater by-pass valve.
Water line leak.
Keep a close eye on that water system. Leak could get interior wet!
Keep us posted on your findings.
Oh, I'm NOT one of those "Know it All's" LOL
