FAQ

Q: How do I know if this switch needs replacing?
A: A pump that won't engage, or a heater that fails to activate despite adequate water flow, can indicate a failing pressure switch.

Q: Can I adjust the pressure setting myself?
A: Yes — this switch features an adjustable set point; consult your spa's service manual for the correct setting procedure.
