Help,Our pressure pump is working eratic,it will pump up to 40 lbs like
it supposed to and kick in at 20.The problem is that if the pump runs
longer than 10 minutes the water pressure goes down to zero although it
still pumps water(this pump is on a small pressure tank 3 gallons i
think).As soon as you Quit running water it builts right up to 40 lbs
and shuts off as normal.I thought it might be the water level but
considering the rain we had i don't think this is the problem,also it is
set up for deep well and the injector is in the well with a 1 inch and
11/4 hose.It does not seem to lose it pressure when watching the guage
so i don't think it is the foot valve.I know a fair amount about pumps
have always fixed my own but this has me stumped.Please help,By the way
it is pretty cold up here in Ontario so am not looking forward to have
to pull the line.Thank you Tom
