What it is

The Potterton Commercial condense stack NRV retrofit kit is a non-return valve assembly for the condensate stack on Potterton Commercial IHE series boilers. It is designed to prevent backflow of condensate within the stack. This kit allows the non-return valve to be retrofitted to existing installations.

Signs this part needs replacing

  • Condensate backing up into the boiler or surrounding pipework
  • Gurgling or bubbling noises from the condensate stack
  • Water leaking from the condensate trap or stack connections
  • Boiler lockout or fault codes related to condensate drainage
  • Visible damage, blockage or debris in the non-return valve

Before you order

  • Confirm the boiler model is a Potterton Commercial IHE 100/300 or IHE 150/300.
  • Check the existing non-return valve location and orientation in the condensate stack.
  • Ensure the boiler is isolated and drained before fitting.
  • Have the installation manual to hand for the correct retrofit procedure.
