TL;DR
A pressure switch setting is the cut-in and cut-out pair that tells a well pump when to start and stop, with factory presets of 30/50 or 40/60 psi and a fixed differential of about 20. The cut-in must also match the pressure tank's air precharge, which is set 2 psi below it, or the system short-cycles and burns out the pump motor.
What it means
A pressure switch setting is the cut-in and cut-out pair that tells a well pump when to start and stop, with factory presets of 30/50 or 40/60 psi and a fixed differential of about 20. The cut-in must also match the pressure tank's air precharge, which is set 2 psi below it, or the system short-cycles and burns out the pump motor. A technician adjusts the spring nuts inside the switch and verifies the precharge with the tank drained.
