Jet Pump losing prime while running
ok - I have a 3/4 hp Gould 2-line Jet Pump built in 1988. Still seems running strong after 22 years. However once every ~two weeks my pump will start to lose prime when I run backwash on my iron filter (filox). Not every time and never when taking a shower, washing dishes, etc. I attribute this to the high volume of water needed for backwashing in the first 13 minute cycle (6-7 gpm). When I hear it starting (I can start to hear the 'air surges' starting and then geting worse and worse), I slow down water volume by partially closing the water valve to the filter, allow the pump to build up again and then turn it all the way full after a minute.
I should note that last year whenever we used a lot of water (showers in the morning) I'd see evidence of water coming up from cracks around the outside of the house (we're on a slab). Not alot but enough to notice it was wet. This leads me to believe theres a crack somwhere in the pressure or suction line.
Any ideas on what is going on and why it only happens about every 6th or 7th time? The worst thing right now is that I can only run backwash while I'm able to listen, not at night anymore. Once we lost prime all the way and it's a pain to keep going to my neighbors hose and hooking up their hose (especialluy when its 20 degrees outside). Thanks...
