What it is

The Gas Valve-Mixer Pipe is a Potterton component supplied under part number 5141429. It forms part of the gas train on Potterton Commercial Sirius WH50 appliances, linking the gas valve to the mixer assembly. It is a boiler spare intended for installation by a competent heating engineer.

Signs this part needs replacing

  • Visible corrosion, pitting or cracking on the pipe surface
  • Gas smell or a detected leak at the pipe joints or unions
  • Soot deposits or discolouration around the gas valve or mixer connection
  • Combustion readings outside the manufacturer's specified range that persist after servicing
  • Physical damage or deformation of the pipe following handling or repair work

Before you order

  • Confirm the appliance model and serial plate details match Sirius 2 WH50 or Sirius 3 WH50
  • Check the existing part number 5141429 against the component being replaced
  • Verify the fault has been traced to the pipe and not to the gas valve or mixer body
  • Ensure the work will be carried out by a Gas Safe registered engineer
