Baxi Pipe Assembly Expansion Vessel 7661761

The Baxi 7661761 is a pipe assembly for the expansion vessel, used on Baxi ErP Combi boiler models. It carries the connection between the expansion vessel and the boiler's hydraulic circuit. The assembly is supplied as a single pipe component for replacement where the existing pipe is damaged or leaking.

• Water weeping or visible damp around the expansion vessel pipe connections
• Repeated loss of system pressure with no obvious leak elsewhere on the boiler
• Corrosion, pitting or scaling on the pipe surface or at the joints
• Debris or blockage restricting flow through the expansion vessel connection
• Pipe deformation or damage found during servicing

• Confirm your boiler model against the fit list above
• Check the existing part number on the boiler or in the manufacturer's parts list
• Inspect the expansion vessel and surrounding connections before ordering, as pressure loss can have more than one cause
• Verify the pipe routing and connection points match your appliance
