 pump cycling
Author: thebot69 (WI)

The well was drilled in 1987 and a new pump installed in 2010. The tank is the one that came with the house so it is old. What should the pressure be when I check? How do I tell if the tank is bad?

You need to turn the power off to the pump, and drain the water out of the tank, then check the air pressure. If you have a 30-50 switch you need about 28 PSI of air, if a 40-60 switch then about 38 PSI. If there's no air pressure at all then most likely the tank is bad and needs replacing. As a quick test if you press in on the air valve before you drain the tank and get a blast of water then the tank is definitely bad.
