What it is

This is the Potterton 400 kW vertical flow and return pipe kit, supplied under part number 5142155. It is a pipework assembly intended for the Potterton Commercial Sirius FS 400 boiler. The kit carries the flow and return connections vertically as part of the appliance's installed pipework arrangement.

Signs this part needs replacing

  • Visible corrosion, pitting or scaling on the pipework or at the connections
  • Weeping or dripping joints that do not seal after tightening
  • Physical damage or distortion to the pipe runs
  • Restricted flow through the pipework caused by internal build-up
  • Evidence of a previous leak, such as staining or residue around the pipe connections

Before you order

  • Confirm the appliance is a Potterton Commercial Sirius FS 400
  • Check the pipe kit reference against the part number 5142155
  • Verify whether the existing installation uses a vertical flow and return arrangement
  • Inspect the surrounding pipework and connections for damage that also requires attention
