What it is

Seal kit from Alpha for the pump, primary heat exchanger and 3-way (diverter) valve on Alpha CB50, CD50 and InTEC 50CS boilers. It supplies the seals required when these components are removed and refitted, helping to restore a watertight joint. This kit supersedes earlier codes 1.011141 and 1.1357.

Signs this part needs replacing

  • Water weeping or dripping from the pump, primary heat exchanger or 3-way valve joints
  • Seals that are hardened, flattened, cracked or swollen
  • Scale, sludge or debris trapped on the seal faces
  • Damp staining or corrosion around the joint
  • Repeated pressure loss that points to a joint rather than a component fault

Before you order

  • Confirm the boiler model against the fit list above
  • Check the existing part number or the codes it supersedes before ordering
  • Isolate the power and water supplies and drain the appliance before starting work
  • Inspect the mating faces for pitting or damage that a new seal will not correct
