Baxi Return Pipe Assembly 7223331

The Baxi 7223331 is a return pipe assembly made by Baxi for the Megaflo System IE ErP range of system boilers. It sits within the appliance's water circuit, carrying returning heating water back through the boiler as part of the normal circulation path. The assembly is supplied as a complete pipe unit for direct replacement of the original component.

• Water weeping or staining around the pipe unions and connection points
• Corrosion, pitting or surface deterioration on the pipe, especially at joints
• Scale or debris build-up inside the pipe restricting flow through the return circuit
• System pressure loss that traces back to the return pipework
• Noise or vibration from the pipework during normal running

• Check the GC number on the appliance data badge against the numbers listed above before ordering.
• Confirm the serial number suffix on the data badge, as fitment differs between the AC and BC build ranges.
