What it is

The Potterton 525 kW vertical flow and return pipe kit, manufacturer part number 5142157, is a pipework assembly intended for the Potterton Commercial Sirius FS 525 boiler.

Signs this part needs replacing

  • Persistent weeping or visible leaks at pipe joints or connection points
  • Corrosion, pitting or surface degradation on the pipework
  • Restricted flow through the flow or return pipework, giving abnormal temperature differentials across the appliance
  • Physical damage to pipework, bends or fixings following installation or service work

Before you order

  • Check the existing pipework is configured for vertical flow and return
