1.5" Bypass Kit for Heat Pumps (White)


Free UK Delivery Over £50

UK Mainland Only (Excludes Highlands)

All Prices include VAT

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.
