With the well water off, and the pressure blead off the system, test the tank with a tire gauge. There should be a snifter valve on the top of the tank under a little black cap. The gauge should read 45 psi. If it does, then you may want to check the settings on your control switch.

I have always heard that the pressure tank should be 2 psi less than the cut-in on the pressure switch. And we don't know it is a 30/50, 40/60, etc.

That's correct and you do that with no water in the tank.
