What it is

The Potterton return collector and seal is a waterway component for Potterton Commercial NXR4I boilers. It gathers the returning heating water from the boiler sections and feeds it back into the circuit, with the supplied seal closing the joint. This item is listed for 11 to 14 section configurations.

Signs this part needs replacing

  • Water weeping or dripping from the return collector joints
  • A seal that has hardened, swollen or visibly deteriorated
  • Reduced or uneven flow of water returning from the boiler sections
  • Localised overheating or kettling noises linked to poor circulation through the collector
  • Scale, corrosion or debris collecting around the collector connection

Before you order

  • Confirm the appliance model and section count, as the part name specifies 11 to 14 sections
  • Inspect the existing collector and seal for damage before ordering
  • Cross-check the part number 5139833 against the appliance documentation
