Biasi Expansion Vessel Connection Pipe BI2112101

The Biasi BI2112101 is a connection pipe for the expansion vessel on Biasi Basica COND and Rinnova Adaptive appliances. It carries water between the expansion vessel and the hydraulic circuit, allowing the vessel to absorb pressure changes as the system heats and cools. The pipe is a moulded assembly specific to these appliance families.

• Water weeping or dripping at the pipe unions or along the pipe body
• Visible corrosion, cracking or perishing on the pipe or its seals
• Loss of system pressure that cannot be traced to any other component
• Staining or residue around the expansion vessel connection point
• Repeated pressure fluctuation after the expansion vessel itself has been checked

• Confirm your appliance model against the fit list above, as the pipe is model-specific
• Inspect the existing pipe and unions to confirm the fault lies with the connection pipe rather than the vessel
• Check the part number BI2112101 against the manufacturer's parts list for your appliance
