What it is

The Halstead 500644 is a flow manifold for the Halstead Finest Platinum gas boiler. It forms part of the appliance's diverter valve assembly, controlling the path of water through the heating and domestic hot water circuits. It is a serviceable component within that assembly.

Signs this part needs replacing

  • Reduced or no domestic hot water flow at the taps
  • Heating circuit failing to reach temperature, or running when hot water is demanded
  • Water weeping from the manifold or the surrounding diverter valve body
  • Scale or debris restricting flow through the manifold
  • Boiler locking out or reporting a flow-related fault

Before you order

  • Confirm the appliance is a Halstead Finest Platinum
  • Locate the part number on the existing manifold or diverter assembly
  • Establish whether the fault lies with the manifold or another component of the diverter assembly
