Hi,
I have a submersible pump and your typical currently available pressure tank with a bladder or rubber liner. The pressure seems good and the well is good, but every 5-6 minutes when the water is running it dries up to trickle and then kicks in again back to normal pressure. The dropping and resurgence only lasts about 10 seconds but is a real pain. I have one pressure gauge which is on the line from the well and prior to the pressure tank. This isn't an abrupt situation, it has been a slow progression over the last year or so. Is this a simple pressure cut off adjustment?
