What it is

The Potterton 5142128 is a condensate trap supplied for Potterton Commercial appliances in the Sirius FS range. It collects condensate produced during combustion and discharges it to drain, while forming a water seal that prevents flue gases from escaping through the condensate route. It is fitted as a serviceable component on the boiler.

Signs this part needs replacing

  • Water collecting or dripping around the trap or its connections
  • A gurgling or bubbling sound from the condensate route during operation
  • Boiler locking out or shutting down repeatedly with a condensate-related fault
  • Visible cracking, distortion or heavy sludge build-up in the trap body
  • Flue gases detected at the condensate discharge point, indicating a lost water seal

Before you order

  • Confirm the boiler model is a Potterton Commercial Sirius FS 400 or Sirius FS 525
  • Check the part number 5142128 against the marking on the existing trap
  • Inspect the condensate pipework and connections for damage or blockages before fitting a replacement trap
