This easy-to-install pressure switch helps regulate water flow by controlling when your pump turns on and off. It maintains consistent water pressure for household, irrigation hose, and other water systems. Suitable for both 110/115V and 220/230V well pumps, it can handle motors up to 2HP, depending on voltage.

Ideal for homeowners, DIYers, and professionals maintaining water access systems, this pressure switch works by reacting to pressure changes in the system—activating the pump when pressure drops, and turning it off once the target pressure is restored.

It's also a practical replacement for worn or outdated well pump switches in residential well systems.

Adjustable Settings for Pressure Tank Compatibility

Pre-set to 20/40 psi, this well pressure switch allows users to easily adjust the pressure differential to match their system's needs—commonly 30/50 or 40/60 psi—making it ideal for systems using a pressure tank. This flexibility supports better control and balance across different plumbing layouts.

For users replacing an older control switch, 40/60 psi remains one of the most popular residential settings for consistent operation.

The well pressure switch is enclosed in a durable cover to protect internal components and ensure reliable long-term performance. A pressure gauge can also be used alongside this switch to monitor system performance and assist with diagnostics.
