What it is

The stool piece is the pump mounting component fitted to Potterton Commercial Paramount boilers, listed by the manufacturer under part number 987691. It forms part of the pump assembly on the 30 kW and 40 kW variants of the Paramount TWO, FOUR and FIVE ranges. Its role is to provide the seating and connection between the pump body and the appliance pipework.

Signs this part needs replacing

  • Visible corrosion, pitting or scale on the stool piece body
  • Staining or residue on the casing beneath the pump connection
  • System pressure loss requiring regular top-ups after pump work
  • Difficulty achieving a clean seal when refitting the pump

Before you order

  • Confirm the boiler is a Potterton Commercial Paramount TWO, FOUR or FIVE
  • Check the appliance output matches the 30 kW or 40 kW rating this part is listed for
  • Verify part number 987691 against the appliance parts list before ordering
