Product details
The Hayward HPX2181 is the water pressure switch for HeatPro heat pumps. It is the genuine Hayward replacement part.
What it does
The heat pump will not run unless it knows water is moving through it. The pressure switch is what provides that proof. It is a safety, and it is doing its job when it stops a unit that has lost flow.
When it is the problem
The classic symptom is a heat pump that reports no flow while the filter pump is clearly running and the valves are open. Once you have ruled out a dirty filter, a closed valve and a clogged basket, the pressure switch itself is the next suspect. Shut off power and isolate the water before you take the old one out.
