2 Line Jet Pump Loses Pressure and Volume/Takes 1 Hr to Recover. Please Help

Leave a comment

By Ifixcars

Hello,
I am new to the forum so thank you in advance for any help. I have a 2 line jet pump in my crawl space that I was told by a plumber is not a shallow system. It had a new pressure tank and pump as of 8 years ago. The well is about 30 years old.

If I run the water, at first I have about 40 psi which is fine for outside use but after just a minute or two the water stops all together. It reduces to just drops. If I turn it off the pump takes an hour to recover and turn off. The pumps comes on at around 25-28 psi and turns off around 38-40 psi. The pressure tank has just under 25 psi in it. I am wondering if I could have a bad ejector or something.

The old pump had low pressure but the volume was ok. The old tank was water logged. Once I had this newer pump and tank installed, the pressure was better but only at the start of each use, then it would drop off. A few years ago the town made me convert to city water but I was allowed to keep my well for outside use. I turn the valve off to the outside hose bibs and drain them in the winter and every spring the pump still has pressure and doesn’t turn back on until I open the valves outside. The problem is that last year and this year the performance has dropped drastically.

Thank you very much
