Side Note: Your water pressure tank should be set to 2 psi below the cut-in pressure (low number). ![]() When you turn the faucet off, the pump will continue to pump until the pressure gets back to 60 psi and that’s when the pressure switch will send a signal to your pump to turn off. The pressure switch senses the drop to 40 psi and that’s when it sends an electrical signal down to the pump to turn on. When someone opens up a faucet, it goes from 60 psi down to 40 psi. For example on a 40/60 pressure switch (most popular option) a home’s water pressure sits at 60 psi. When you open up a faucet the pressure drops. You may hear the terms “cut-in pressure” and “cut-off pressure” = cut-in pressure / cut-off pressure. The second number tells the pressure switch to send a signal down to your pump to turn off. The first number is what tells the pressure switch to send a signal down to your pump to turn on. These numbers represent the pressures that your pressure switch is tuned to in the water line. It is used with submersible well pumps and jet pumps. As time goes on, the spring becomes weak and the electrical contacts wear out which can make it seem that your pump isn’t working quite right. The pressure switch has a spring on the inside that’s connected to electrical contacts.
