How do you test a pressure switch on a well pump?
Check and clean the switch relay contacts. Examine the four contacts for burning or pitting on the surface. If you see signs of damage, you may need to replace the pressure switch. If not, use a piece of fine-grit sandpaper or an emery board to clean away any dirt or debris until you reveal the shiny metal.
What does a pressure switch do on a well pump?
Pressure switches monitor your water system to electrically “start” or “stop” your pump at pre-set water system pressures. Pressure switches are used on submersible, reciprocating and jet pump systems. In a well system, pumps are used to bring water from the well and to pressurize the piping system in the home.
What should the pressure be on a well pump?
A pressure switch is a switch that signals to the well pump to start or stop pumping depending on the pressure in the water system. Pressure switches are designed to have two pressure settings: cut-in and cut-off pressure. These are the numbers you may find on the switch itself and they typically are 40-60, 30-50 or 20-40 measured in psi.
When does the pressure switch on a well pump turn off?
It turns off when the maximum PSI is reached. The pressure switch is comprised of an internal spring mechanism which is connected directly to electrical contacts. As the pressure switch ages, these components can weaken and malfunction, at which time replacement is necessary.

How often should a pressure switch be replaced?
It may not be a wear part in its traditional meaning, but a pressure switch may need to be replaced several times during your home ownership. Now that you know what a pressure switch does and how it works, it’s a bit easier to troubleshoot problems with your well pump.
Can a pressure tank switch be connected to a well pump?
The pressure tank switch and well pump will be wired together on the same breaker, so if you see a label that reads “water pump” or “well,” you’ve found the right breaker to shut off. Once you are certain the power to the pressure tank switch is off, follow these steps to test the well pressure tank switch:
What happens when there is no pressure on a well pump?
If the contacts are held open and there is no water pressure, attempt to cycle the switch by pulling the contacts open. This may dislodge the internal spring. If the switch closes, turn the power back on. If the contacts remain open, and there is no water pressure, the switch is bad.
What to do if your well pump switch is gone?
Over time, the spring mechanism weakens, along with an electrical malfunction of the contacts. Shut off the electricity to the well pump system. Switch off the circuit breaker or remove the fuses that supply the electrical power. Access the switch mechanism by removing the cover to the pressure switch.
What’s the pressure on a witch well pump?
These are the numbers you may find on the switch itself and they typically are 40-60, 30-50 or 20-40 measured in psi. The lower number is the pressure at witch the pump will kick in and start filling up your pressure tank. The higher number is the pressure at which the pump will stop.
