Hi - I am selling my home and the buyer’s home inspector tested my well flow. The well flowed at 3.5gpm until the flow rate dropped and he stated in his report “ran out of water” at 32 minutes. It was given a 1 minute rest and then “ran out of water after 1 minute.” When I spoke to him in person, he said that the well actually did not run dry, the flow just dropped signficantly. He wrote up the well as “failed the well test.” He said he ran it the first 20 minutes to drain the pressure tank. He said it needed to produce 3.5gpm to pass…which it did according to how I read the report.
I have spoken to some other inspectors and a well driller who said that they use a different test, more like 15 min on 15 min off for 3 to 4 hours and then determine flow rate. I could not find any “standard” test in the state (PA) or local codes.
When I bought the house, my inspector ran it for 3 hours with periodic 5 minute rests and it produced 2.5gpm average, but then was cleaned out and produced 4gpm.
I am having it cleaned out and re-tested. My question is: is there a definitive “right” or “wrong” way to test the well flow? I’ve never run out of water during normal household use and the pressure is just fine.
