What it is

The Potterton 10/18728 is an automatic air vent used on Potterton gas boilers, including the Puma, Ultra 2 and Ecotherm families. It continuously releases trapped air from the heating circuit, helping to prevent airlocks and keep system pressure stable.

Signs this part needs replacing

  • Water weeping or dripping from the vent body
  • Boiler pressure dropping with no visible leak elsewhere
  • Gurgling or air noise in the system after bleeding
  • Vent no longer releasing air, or the float inside is stuck
  • Scale or corrosion deposits around the vent

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the part number on the existing vent matches 10/18728
  • Isolate the boiler and depressurise the system before removal
  • Inspect the vent seating and sealing face for damage before refitting
