AstralPool Hurlcon Gas Pool Heater Pressure Switch Water Flow Sensor HX WX JX MX
AstralPool Hurlcon Gas Pool Heater Pressure Switch
The AstralPool / Hurlcon Pressure Switch is a critical safety component used in HX, WX, JX and MX gas pool heaters. This switch detects water flow through the heater and prevents operation if flow is too low.
If your heater is not igniting, shutting down, or showing flow-related errors, a faulty pressure switch is one of the most common causes.

HeaterFix gave us great service in replacing our Hurlcon HX120 spa heater. We didn’t expect to see it until November, but it arrived in a week and is installed. Well done Jason.

He had our Pool Heater installed a few weeks ago, and the advice on the best location and positioning was more than just fit and leave it was working within the space and surroundings to suit our needs. Price is important, but you always remember the quality. Thank You.

This is one professional Company. I had an issue with my gas spa heater. I spoke with Jason who guided me through a couple of self checks and finally isolate the problem. His advise and knowledge was outstanding. The parts were promptly sent, installed and operation is perfect. Highly recommended.
