This Lay-Z-Spa Pump is a replacement for the heater pump supplied with your Lay-Z-Spa. Please note, this has a UK Plug and does NOT have Wifi capability. It is essential for heating the water, filtering the water, and operating the massage system. If your existing pump is damaged, this replacement is a vital piece of equipment. Without a working pump, you’ll be unable to use your Lay-Z-Spa. The pump also has a timer function to heat up the water at a designated time. The pump is grey in colour and is compatible with all Lay-Z-Spa Airjet models (not HydroJet models).
