What it is

The Biasi BI1131101 is a by-pass pipe assembly used in Biasi gas boilers. It forms part of the hydraulic circuit, allowing a controlled flow of water around the primary circuit to maintain correct differential pressure across the heat exchanger. This version is specified for appliances up to serial number N012040206.

Signs this part needs replacing

  • Kettling or rumbling noises from the boiler during operation
  • Poor temperature stability on heating or hot water
  • Leaks or weeping at the by-pass pipe connections
  • Scale or debris restricting flow through the pipe
  • Overheating or lockout linked to poor circuit circulation

Before you order

  • Confirm the appliance serial number is up to N012040206, as later builds use a different by-pass pipe
  • Check the model against the fit list above
  • Inspect the existing pipe and its connections for damage or blockage before removal
  • Verify the part number BI1131101 against the manufacturer's parts list for your appliance
