I have a seasonal cabin with a shallow 1/2 hp jet pump sitting piggy back on a horizontal bladder tank 1 year old.
The water pressure seems fine until the pump turns on, when in the shower at that point, the hot & cold starts coming in alternately rather than mixed warm.
I've watched where the pump kicks in a few times, but hadn't noticed where it kicks off, but just before I left yesterday, I think I noticed the pump kick in at around 30#, but then drop immediately to around 5# and start to build from there, and bouncing by about 20# when in the 15-25# range (rapidly fluctuating between say 15 & 35# while gradually increasing overall) until it gets up above around 35#, then the pressure begins to steadily build until it shuts down just shy of 50#. The system holds the pressure fine, and I don't believe it's cycling when no water is being used. Unfortunately, I won't be able to confirm that it dropped immediately after kicking in until the next time I'm there, and I'd like to have whatever I need to fix it with me when I get there.
So, is my pump somehow letting the pressure blow back down the well when it first starts up, or what else could the problem be? I don't know much about pumps & wells, but that seems the only logical answer, but why would it hold pressure until it runs?
And finally, if that is the problem, do I repair the pump(with what?), or replace it?
Obviously my first time post, thank you very much for any insight!
