What it is

This is a plug for the condensate trap and syphon assembly, supplied complete with its O-ring. It is a Potterton Commercial part, listed under part number 7661027, and is used on Potterton Commercial Sirius 2 and Sirius 3 boiler ranges. Its function is to close the trap or syphon body and seal the joint so condensate is retained and drained correctly.

Signs this part needs replacing

  • Water weeping or dripping from the condensate trap or syphon body
  • Visible staining or corrosion around the trap joint
  • A perished, flattened or missing O-ring at the plug
  • The syphon failing to hold its water seal, causing condensate to drain away too quickly
  • Boiler lockout or condensate-related fault codes linked to a leaking trap

Before you order

  • Confirm the boiler model against the fit list above, as the plug suits Sirius 2 and Sirius 3 units only
  • Check whether the fault lies with the plug and O-ring or with the wider trap or syphon assembly
  • Inspect the trap body seating and threads for damage before fitting a new plug
  • Have the part number 7661027 to hand when ordering
