In response to Re: Shollow well pump losing prime
: : Background: We live about 30 miles SE of Fairbanks, Alaska. We just replaced a old Gould 1/2 HP pump because it was losing prime..thought it was the pump (also making alot of noise).
: : Replaced it with a Flotech 3/4 HP jet pump. It too is losing prime UNLESS I shut the water off to the house so it is just the pump and the pressure tank.
: : I am thinking it might be a leak somewhere in the house that is causing the pump to lose prime.
: : I have a brass backflow inhibitor (not sure what the correct name is) valve between the pump and the well.
: : Should I also have one between the pressure tank and the house? Any ideas?
: : Thanks in advance!!

: A jet pump loses its prime somewhere between the pump and the water source (well).. It can be a leaking intake line, a faulty FOOT VALVE,Check valve. If the leak is on the house side of the pump, a leak will cause the pump to cycle quite often, but will not cause it to lose prime. The prime is lost on the incoming side to the pump.Hube

Thanks, Hube!!
There was no foot valve so I purchased that and a new pvc pipe. Will install this weekend.
