What it is

The Alpha inlet manifold assembly 3.013768 is the manifold block that sits below the diverter valve on Alpha CB and HE series gas boilers. It forms part of the boiler's water circuit, directing flow through the diverter valve assembly. It is supplied as a complete manifold assembly.

Signs this part needs replacing

  • Water weeping or staining around the manifold block below the diverter valve
  • Visible cracking, corrosion or scale build-up on the manifold body
  • Loss of system pressure with no other obvious source of leakage
  • Poor or inconsistent hot water delivery linked to restricted flow through the manifold
  • Dampness or limescale deposits at the manifold joints and seals

Before you order

  • Confirm your boiler model against the fit list above, including the LPG variant
  • Check the GC number on the appliance data badge where available
  • Verify the existing part number 3.013768 on the manifold before ordering
  • Inspect the surrounding diverter valve and seals for related wear
