Read over the information at the 2 links below and see if these situations are similar to yours. I believe you may have a bad check valve on your pump, but the pressure being low is not something I would expect to see with that. Normally the pump will run and then off, run and then off, etc... and have low pressure, which means there is an air problem in the tank or with the bladder (in the tank).

Thank you for your question on the well pump.

No the pressure switch is different from the flow control valve.

The pressure switch is an electric switch that opens the contacts to the motor when it reaches the cut off pressure.

It could be the nose of the impeller and the diffuser are worn and causing slippage and the volume the impeller pumps is decreasing.

It is a little hard to know for sure until you replace some of these parts.

If the system is leaking down and loosing pressure I would look at the storage bladder tank and the check valve on the nose of the pump for leaking and not holding the pressure in the pump and tank.

You will have to remove the fitting at the end of the jet on the front of the front where the well pipe connects to clean and check the check flow valve.

Please let me know what you have found, and we can continue our troubleshooting based on that.

Thank you for using Manage My Life.
