What Is a Pump Pressure Switch?

2023-03-31

A Pump Pressure Switch is a device that activates or deactivates your well pump when pressure thresholds are reached. This helps optimize your home’s water supply by reducing the amount of work that the pump has to do and ensuring it doesn’t run unnecessarily.

The best applications for a pressure switch are high-pressure pumps that require extended times of inactivity or transition periods between spray times. These include portable sanitation systems for cleaning porta potty units, soft wash sprayers, and other mobile devices that don’t need to run their motors while in transit between spray sessions.

Common types of pressure switches

The most popular and widely used type of mechanical pressure switch is the diaphragm or piston. It senses the pressure of a fluid and mechanically activates the switch when the pressure increases to the set or cut-on point.

It has a piston, spring, and a setpoint adjustment screw that can widen or narrow the operating pressure range of the switch. Some switches have separate springs for the set and cut-on points, while others have a single spring that can modify both ends of the pressure range.

Other features of a well pump pressure switch include electrical contacts that allow current from an external power source to pass through them when they touch and terminals that connect the power sources to the contacts. These components are usually located in the switch housing.

If your well pressure switch is faulty, it may not be able to accurately detect the pressure levels within your water system and trigger an on or off signal to your pump. This can lead to issues with your well pump and the system itself, including low or no water pressure and waterlogged pipes.
