What it is

The DHW flow valve, part number 6.5629950, is an Alpha component that forms the front half of the diverter assembly on Alpha 240 and 280 series gas boilers. It sits in the domestic hot water circuit and controls the flow of water through the diverter section. Its role is to regulate DHW flow so the boiler responds correctly to a hot water demand.

Signs this part needs replacing

  • Reduced or inconsistent domestic hot water flow at the taps
  • The boiler fails to respond to a hot water demand
  • Water weeping or dripping from the diverter area
  • Poor or fluctuating DHW temperature during draw-off
  • The valve feels stiff or fails to move through its full travel

Before you order

  • Confirm your boiler model and, where shown, the GC number against the fitment list
  • Check that the front half of the diverter is the section requiring replacement
  • Verify the part number 6.5629950 matches the component currently fitted
  • Inspect the surrounding diverter components for wear before reassembly
