Hi, i fixed the leaky inline filter on my pump. The pump still keeps running after i shut off the faucet. There is one thing of interest. Not sure what it means. I hooked up the city water and ran it for awhile, filling up the hwh, completely, ala prv. I closed the prv, unhooked the city water, bypassed the hwh, and turned on the pump. The pump didn't run, until i turned on the faucet. Then, it wouldn't turn off after i closed the faucet. Does that mean the pressure switch is good?

It might mean that. Sounds like you "captured" pressure in the system that was supplied by the city water. When you opened the faucet (hot water?) the pressure bled off and then, since the hot water tank was bypassed, there was no more supply to pressurize the line via the pump, so it kept running.

I think I'd wait till spring and you can fill all the fresh water tankage to pass final judgement though. Replacing the pump is a pretty easy task, if it's at all like mine, and these pumps are available at any RV place or online.

Thanks Jack. I was trying to duck the expense of a whole pump. I could get a repair kit for half price... Alas, I think i'll bite the bullet on this one.

I would also check your city inlet(where you hook up the hose) , on mine it was dripping and was a point of pressure loss.
