Pressure Switches
Pressure switches confirm that adequate water flow is present before allowing the spa heater to activate, protecting the element from dry-fire damage. When a pressure switch fails, the heater may refuse to turn on even when water is flowing correctly, or it may allow the heater to run without flow. Spa Guy Parts carries replacement pressure switches for most hot tub heater assemblies. Restoring proper pressure switch function keeps your heater safe and your spa operating correctly.
