1/2 hp Red Lion shallow well jet pump, 20 gal pressure tank, well water table was measured 8 feet down the well pipe.
When priming the pump, water came steady but not at a good rate. Not knowing how fast the water should come out without going through the pressure tank I finally just closed the drain and let things fill up. The pump always sounded like it still has air in it or something rattling around.
After several days and some investigating I found at first one leak at the pressure switch line going out from the pump, fixed that and a day later I found another leak of the line going into the switch, fixed that as well. The pump is still noisy and it takes 8 minutes to replenish the pressure tank even though no water is running in the house. It pressurizes with lots of slurping noises to 50 psi and shuts off.
My question is: Where should I start trouble shooting without having to tear everything apart? I already checked for air leaks with soap suds. Is it possible the pump was damaged during priming due to the two existing leaks?
Thank you! Susi
