What it is

The SUPPLY MANIFOLD is a Worcester Bosch component used in Greenstar combi boiler assemblies. It routes the incoming water supply to the points where it is needed inside the appliance. It is identified by part number 8737604679.

Signs this part needs replacing

  • Visible leakage or weeping from the manifold body or its connections
  • Water tracking or staining around the manifold area inside the casing
  • Cracks, deformation or heat damage to the manifold
  • Loss of flow or pressure symptoms traced to the manifold
  • Scale or debris build-up restricting flow through the manifold

Before you order

  • Confirm the boiler model and GC number against the fitment list
  • Check the existing manifold part number where it is marked on the component
  • Confirm whether the manifold or its seals and connections also require attention
