How do I know if my pressure switch is 30 50 or 40 60?

Keep an eye on the pressure switch as you wait for your submersible well pump to start. If the pump starts at 30 psi, it’s likely that your tank is set to 30/50. On the other hand, if the pump starts at 40 psi, it’s probably set to 40/60. To verify, simply turn off the faucet and wait for the well pump to shut off.

How does a 40 60 pressure switch work?

When the pressure switch detects a decrease in pressure to 40 psi, it activates an electrical signal that triggers the pump to turn on. After you turn off the faucet, the pump will keep running until the pressure rises back up to 60 psi. At that point, the pressure switch will send a signal to the pump to shut off.
