Hot Tub & Jacuzzi® Flow & Pressure Switches

Within your Hot Tub there will be a pressure switch or flow switch which monitors how the hot tub operates. The pressure and flow switches within the hot tub are a form of safety device which will turn off the heater if the water flow is interrupted. These parts are closed during the normal operation of a spa and will quickly open if a pump fails or an air pocket forms within the hot tub. This function is a security feature to prevent a meltdown of the heater in the event of an equipment failure. In the event this occurs, your hot tub may show a Flow Malfunction but please check your hot tub manual for further information.

For help locating the part you are looking for please email a photo to with as much information as possible on your make and model of hot tub and someone will be in touch to help.
