Ideal Pipe Return C26-32-40 S18-26-32 176861

The Ideal 176861 is a pipe return assembly for Ideal Vogue condensing boilers. It forms part of the boiler's water circuit, carrying cooler water back from the heating system into the appliance so it can be reheated. The part is listed under Ideal's hoses and pipes category and is matched to the C26, C32, C40, S15, S18 and further Vogue variants.

• Water weeping or staining around the return pipe connections or unions
• Visible corrosion, pitting or scale build-up on the pipe surface
• Boiler losing pressure repeatedly with no obvious external leak elsewhere
• Kettling, gurgling or uneven circulation traced to a restricted return path
• Pipework disturbed or damaged during a heat exchanger or pump repair

• Confirm the boiler model and GC number against the compatibility list, as Vogue variants use different return pipe arrangements
