What it is

The Alpha 3.013303 is a coupling alignment pin used on the 3-way diverter valve assembly. It locates and aligns the coupling that links the valve to the boiler's diverter mechanism. It is specified for Alpha CB50 and CD50 LPG appliances.

Signs this part needs replacing

  • The 3-way valve coupling is loose or misaligned, so the valve does not seat correctly.
  • Domestic hot water or heating mode fails to switch as expected.
  • Visible wear, corrosion or deformation on the pin.
  • The pin is missing or has worked free from the coupling.
  • Repeated valve operation faults after the coupling has been disturbed.

Before you order

  • Confirm the appliance model is an Alpha CB50 (LPG) or CD50 (LPG).
  • Check the existing pin against the valve coupling to confirm the correct part.
  • Verify the fault lies with the coupling alignment pin rather than the valve body or actuator.
  • Have the boiler model and part number 3.013303 to hand when ordering.
