Ariston Pipe Pump to Main Heat Exchanger 65102573

The Ariston pipe (part number 65102573) is the connecting pipe that runs between the pump and the main heat exchanger. It is used on Ariston Microgenus MFFI HE UK appliances, where it carries primary circuit water between the two components. The pipe forms part of the sealed heating circuit and must be sound at both connections to maintain system pressure.

• Visible weeping or damp staining at either end of the pipe
• Corrosion or pitting on the pipe body, particularly around the connections
• Loss of system pressure that cannot be traced to any other component
• Restricted flow or debris build-up inside the pipe causing poor heating or hot water performance
• Noise or vibration from the pump area linked to a partially blocked or damaged pipe

• Confirm your appliance model against the fit list above
• Check the GC number on the appliance data badge matches your model variant
• Inspect both pipe connections and seals for damage before fitting
• Verify the existing pipe is marked with part number 65102573
