About This Item

The Hayward Pressure Switch (CZXPRS1105) is the OEM replacement water pressure switch designed for Hayward pool and spa heaters.

IMPORTANT: PROFESSIONAL INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician. Do not attempt to service high-voltage heater components without proper certification.

The pressure switch monitors water pressure within the heater circuit and signals the control board to allow or interrupt heater operation based on detected flow conditions. Replacing a failed pressure switch restores proper heater interlock function and protects the heat exchanger from dry-fire damage.

Poolaroo Pro Tip

Before replacing the pressure switch, confirm that water flow through the heater is adequate — a clogged strainer basket or partially closed valve can mimic a failed pressure switch by triggering the same fault. Once you've verified flow is correct and the switch still fails to close, this OEM replacement restores the original switching threshold. Always shut off power to the heater at the breaker before disconnecting or reconnecting any electrical components. Have a licensed pool technician perform the replacement if you are not certified to work on mains-voltage pool equipment.
