The bypass kit is recommended for installation of all heat pumps

Installing a bypass allows you to isolate the pool heat pump in winter while still allowing water to circulate around the pool water circuit to prevent freezing.

The bypass can also be used to adjust the water flow through the heat pump by slightly opening or closing the bypass valve.

(note that the kit does not include pipe or glue)

The kit is available in four sizes:-

  • 1.5"
  • 2"
  • 50mm

To see which size you require, look at the writing stamped on your existing pool pipework.

(do not just measure the external diameter of your existing pipes as this is different)
