What it is

The S1045200 is a pipe manufactured by Saunier Duval that connects the heat exchanger to the three-way valve. It forms part of the hydraulic circuit on Isofast Condens F35E appliances, carrying water between the two components. The pipe is supplied as a single component for replacement where the existing pipe is damaged or leaking.

Signs this part needs replacing

  • Visible water weeping or staining around the pipe connections
  • Corrosion or pitting on the pipe surface
  • Scale build-up restricting flow through the pipe
  • Loss of system pressure traced to the pipe run
  • Physical damage or deformation of the pipe

Before you order

  • Confirm the appliance is an Isofast Condens F35E
  • Check the appliance serial number against the two fitment variants listed
  • Inspect the pipe connections and seals for damage before fitting
  • Verify the pipe routing between the heat exchanger and three-way valve matches the failed part
