I recently installed a new 1hp convertible jet pump on an existing 20' shallow well. I have a precharged pressure tank connected to a second output of the pump. The water level is about 3' below grade and draws down to about 5' below grade when the pump is running.
My problem is that I am only getting about 9.5 gpm at 40 psi. (For those that read my other question, I mis-measured the first time.) The manufacturer says I should get 15.0 gpm at 40 psi at a pumping depth of 10 ft. I know that the manufacturer probably gives ideal conditions, but I would have thought I would have come closer to 15 gpm. Do you have any ideas why I wouldn't be getting a higher flow?
I have a 1-1/4" PVC suction line down about 15 ft with a foot valve. And I have a 1" galv discharge line. I don't lose any pressure when the system is off, so I don't think there are any leaks.
Thanks for any help!
