What it is

This is the return and distribution pipe for Potterton Commercial NXR3i boilers, supplied as the 6-8 section variant under part number 5140639. It forms part of the boiler's internal water circuit, carrying water between the return and distribution points across the section assembly. The pipe is a Potterton Commercial spare intended for servicing and repair of the NXR3i range.

Signs this part needs replacing

  • Weeping or visible water at the pipe connections or along its length
  • Corrosion, pitting or surface deterioration on the pipe wall
  • Water staining or dampness in the boiler casing around the pipe run
  • Reduced flow or uneven heat distribution across the boiler sections

Before you order

  • Confirm the boiler model is an NXR3i and note the number of sections fitted
  • Check that the 6-8 section variant matches the pipe currently installed
  • Inspect the connecting joints and seals, as these may also need attention
  • Verify the part number 5140639 against the existing component before ordering
