Worcester Bosch Heat Exchanger Pipe to PR Valve 87161001120

The Worcester Bosch 87161001120 is a formed pipe that links the heat exchanger to the pressure relief valve on the appliance. It carries water between the two components and forms part of the pressure-relief circuit, so any restriction or leak at this pipe affects how the appliance manages system pressure. The part sits within the Worcester Bosch Hoses & Pipes group and is used across the Camray 5 Combi and Cam 5 Combi range.

• Water weeping or staining around the pipe ends or along its length
• Pressure gauge reading dropping steadily with no other visible leak on the system
• Corrosion, scale build-up or pitting on the pipe surface
• Kettling, gurgling or irregular pressure behaviour traced to the relief circuit
• A joint that will not seal after re-making, indicating a distorted or damaged pipe

• Confirm the appliance model and serial number against the compatibility list before ordering, as pipe routing differs between variants.
• Check the existing pipe against alternative number 1013211 to confirm you are matching the correct component.
• Inspect the sealing washers or olives at both ends and replace them if they are compressed or perished.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
