Pressure switches and sensors are fitted to hot tubs to monitor operating conditions. Correct fitting and adjustment ensures your spa is operating safely.
Sensors and Switches There are no products in this category.
Pressure switches protect your hot tub against low flow situations, which would otherwise result in damage to your hot tub 'workings'. When flow is insufficient through the heater the pressure switch shuts off the heater. Most pressure switches are adjustable, but make sure that water flow isn't restricted by another cause first (such as dirty filters) before making adjustments.
These temperature sensing devices are present to protect your spa from overheat conditions. Sensing bulbs are gas-filled and some may have adjustment facilities.
