Flow & Pressure Switches

Flow & Pressure Switches

Pressure & Flow Switches

This category contains all the replacement pressure and flow switches that are used with hot tubs and spas.
These types of switches are used as part of the heating system to determine if there is sufficient water flow passing through the heater assembly. If the filters are dirty or if the filter and heating pump has failed power will not be sent to the heater, this prevents damage to heater element inside the assembly.

Often flow switches internal micro switch will fail or a pressure switch internal diaphragm will get stuck open or closed, these faults will cause FL errors and the switch will need to be replaced.
