What it is

The Biasi BI1171106 is a by-pass pipe used within the return group assembly on Biasi high-efficiency gas boilers. It forms part of the hydraulic circuit, controlling flow through the return group. This variant applies from boiler serial number N100970706 onwards.

Signs this part needs replacing

  • Water weeping or damp traces around the by-pass pipe or its connections
  • Visible corrosion, pitting or rust staining on the pipe
  • Scale or debris build-up restricting flow through the by-pass
  • Boiler noise or unstable temperature behaviour linked to by-pass flow
  • Physical distortion or damage to the pipe

Before you order

  • Confirm the boiler serial number is N100970706 or later
  • Check your appliance model against the fit list above
  • Inspect the surrounding return group components for related wear
  • Check whether seals or washers for the pipe connections are required separately
