What it is

This is the domestic hot water (DHW) flow valve fitted to affected Alpha boilers, which detects the flow of water when a hot tap is opened and triggers the boiler to produce hot water, supplied together with seal kit 740 for the DHW heat exchanger. It is a genuine Alpha part, number 6.5629960A.

Signs this part needs replacing

  • Boiler does not fire when a hot tap is turned on
  • Reduced or fluctuating hot water flow
  • Water still trickling through when taps are shut
  • Noisy or juddering operation when hot water is drawn off

Before you order

  • Isolate and drain the relevant circuit before removing the old valve
  • Fitting should be carried out or checked by a Gas Safe registered engineer
