Hayward HAXPSA1930 Water Pressure Switch Assembly

What This Part Is Used For
The Hayward HAXPSA1930 Water Pressure Switch Assembly monitors water flow through the heater and allows ignition only when proper circulation is present. It helps prevent the heater from firing when there is insufficient flow.

Why This Part Matters
A failed pressure switch can cause nuisance shutdowns or prevent the heater from starting at all. It also plays a safety role by stopping operation during low flow conditions caused by dirty filters, closed valves, or pump issues. Replacing a faulty switch restores proper heater operation and protects the heat exchanger.
