Recently our non-bladder expansion tank became waterlogged so the pump would start overcycling. It would run a few seconds then turn off, then turn right back on again for as long as the faucet was open.
From the information I've found on the internet, it seems I have more than one problem.
After draining the 42-gallon bladderless expansion tank and installing an NPT Schrader Valve, I was able to pressurize the tank with a bicycle tire pump, and things were back to "normal" for now, but I have a feeling the issue will return because nothing was actually fixed.
Giving the plumbing a good check it seems a few things are not right.
I suspect there is a problem with the air volume control and would like to replace it but I cannot find an exact replacement. Invensys 0718D
Then I noticed the AVC tubing is currently connected to the Water Pressure Switch instead of the AVC Port on the MSE-7 Pump.
Then I found that the Pump Pressure Regulator port that the Water Pressure Switch tubing was supposed to connect to was plugged.
