About This Item

The Hayward Water Pressure Flow Switch (HPX2181) is the OEM replacement flow-sensing pressure switch for Hayward pool and spa heating equipment.

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 this component without appropriate certification.

This pressure switch monitors water flow through the heating system and signals the control circuit to confirm adequate flow before allowing heating operation. Replacing a faulty flow switch restores proper safety interlock function and prevents the heater from operating under low- or no-flow conditions.
