What it is

The Vaillant 0020231130 is a hex inlet tube used on Vaillant HOME series appliances. It forms the inlet connection to the heat exchanger (hex) assembly, carrying water into the primary heat exchanger circuit. It is a serviceable pipe component supplied as a single part.

Signs this part needs replacing

  • Water weeping or staining around the heat exchanger inlet connection
  • Visible corrosion, pitting or scale build-up on the tube
  • Kettling or restricted flow traced to the inlet pipework
  • Physical damage, distortion or a crushed pipe end at the connection
  • Repeated pressure loss with no other obvious source on the appliance

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check the part number 0020231130 matches the number on the existing tube or the manufacturer's parts list
  • Inspect the mating connection and seals for damage before refitting
  • Isolate the appliance and drain down before removing the existing tube
