On well water at 40/60 cut in / cut out.
Pressure drops 5 psi every 30 minutes or so. Pressure continues to drop at the same rate with valve to house shut off.
With power to pump shut off, pressure will drop at the same rate to 40 and then jumps to 0. Similarly, when I connect the power back to pump, the pressure gauge jumps to 40 psi then continues on to 60psi before shutting off.
Recently, while the gauge is at 0 psi, I checked and pressure tank was at 32 psi. So, I pumped it up to 38psi. No water at the air valve.
Refilled the water, same rate of drop-off, the only thing that changed was it jumped to 50psi when I turned power back to pump.
Also pulled the pump pipe and there's water on top of the pipe. So, it's not check valve issue, correct?
Is it a leak or is it pressure tank? Should it be jumping from 0psi to 40psi the moment power to the pump is connected?
Edit: Just bought this house a year ago and recently noticed this issue. Not sure the history or when it started. But the pressure tank has some sticker with December 2018 date. Not sure if it's helpful, I also found paperwork showing pump replacement about 10 years ago ... 1hp pump on a 190' well.
Thank you.
