The official Lay-Z-Spa® Descaler removes calcium deposits to improve the efficiency and prolong the lifespan of the heater pump. Regularly descaling a Lay-Z-Spa pump will improve the flow of water and general efficiency by removing limescale/calcium deposits from the heater, circulation pump and flow sensor. Frequent descaling is highly recommended for areas of the UK with medium or hard water. Compatible with all Lay-Z-Spa pumps, including AirJet™, HydroJet™, HydroJet Pro™ and UltraFit™, the descaling tool is designed to create a short, closed water circuit inside the pump for the circulation of specific descaling chemicals (not included). How to use the Lay-Z-Spa® Descaler: Disconnect the pump from the main hot tub (except UltraFit™ hot tubs).
