Lay-Z-spa Hot Tub Lime Descaling Tool

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 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). Connect the descaler to the water in and out pipes following instructions with the correct adaptors. Fill up to the minimum line with your preferred descaling product. We recommend either a 50/50 mix of water and white vinegar or Approx 200ml of ClearWater Scale & Stain Controller diluted in water. Screw on the lid to create a safe and closed water circuit. Option 1: Set the temperature to 30-35°C and activate the heater (this will automatically run the filter cycle) and run for 30 minutes Option 2: Do not activate filter or heat and leave the descaling solution for a minimum of 3 hours. Unscrew the drain valve on the descaler to empty the liquid and detach the descaler. Flush clean water through the pump for 2 minutes using a hose.
