What it is

The S1028300 is a sanitary hot water pipe manufactured by Saunier Duval. It forms part of the domestic hot water circuit on the Isofast Condens F35E boiler. The pipe carries heated water through the appliance's sanitary hot water side.

Signs this part needs replacing

  • Visible water weeping or dampness around the pipe or its connections
  • Corrosion, pitting or surface staining on the pipe wall
  • Scale build-up restricting flow through the sanitary hot water circuit
  • Kinks, cracks or deformation in the pipe run
  • Water pooling inside the boiler casing beneath the pipe

Before you order

  • Confirm the appliance is an Isofast Condens F35E
  • Check the boiler serial number is below 0400446159, as later builds use a different arrangement
  • Inspect the pipe connections and seals for damage before fitting
  • Verify the part number S1028300 against the manufacturer's parts list for your appliance
