  • Everything works better when serviced; this kit contains everything you would need to give your pump a new lease of life.  As long as you are confident with a screwdriver, all parts are relatively straightforward to replace.  Our team is also here and happy to help should you need some guidance.


    Our AirJet Pump descaling solution acts as a versatile aid, functioning as a miniature hot tub for pump descaling and testing purposes. This feature allows you to diagnose and resolve issues, including leaks, worn-out components, and error codes. Additionally, it serves as a remedy for preventing FreezeGuard related initialization problems, which may trigger an E02 or E03 error when inflating your spa during colder weather.


    Regular descaling of your pump will help improve water flow by eliminating calcium deposits from critical components such as the heater, circulation pump, and flow sensor.


    Our Service Pack Four (SP04) includes three descaling tablets and a replacement set of external gaskets as these often perish through contact with chlorine. In addition you will receive all the parts you will need to fully service your Filter Pump (model #58113 or P4071), and aluminium PTC heater (220 or 110 Volt) assembly and flow sensor housing. The kit is compatible with AirJet pumps of both legacy 'egg' and newer flip up display designs.
