I have an artisian well that is 138 feet deep. The pump is in the ground. I have apressure(baldder style) tank inside where the well connects to the hous plumbing.
The pump will run, build pressure and shut off at 62 lbs of pressure. It will begin to loose presure 5-7 lbs in within 20 second. Then the pressure loss slows and after about 15 -25 minutes, the well kicks back on at 32 lbs of pressure. This happens if I turn off the main valve to the house (no water coonssumption possible), I have no leaks inside or outside, toilets are not running.
How would I dianose the loss of pressure. The well, the pump and pressure tank are about 2 years old. This is a new home, well had very little use during the first year.
