Hayward FDXLWPS1931 Pressure Switch

Hayward Pressure Switch for FD Heaters

The pressure switch in your heater is designed to ensure water pressure is adequate for functioning, and when it fails, it will prevent your heater from turning on to prevent further damage to other components. After years of exposure to pool chemicals, heavy water flow, and the elements, your heater will need service to continue functioning at its best.
