Worcester Bosch Flow Pipe 87107353580

The Worcester Bosch 87107353580 is a flow pipe that forms part of the internal pipework on Greenstar CDI appliances. It carries water through the boiler's hydraulic circuit and keeps the routing between components correct, so circulation and heat transfer behave as the design intends. The pipe is supplied by Worcester Bosch as a replacement for the factory-fitted item on the models listed below.

• Water weeping from the pipe ends or at the joints where it connects into the hydraulic assembly
• Corrosion, pitting or heavy scale build-up on the pipe wall
• Repeated loss of system pressure with no obvious external leak
• Damp staining or drips visible inside the appliance casing
• Flow-related fault codes or poor circulation traced back to a restricted or damaged pipe

• Check the GC number on the appliance data badge against the compatibility list before ordering.
• Confirm the part number 87107353580 or the alternative number 1012575 matches the pipe currently fitted.
• Inspect the surrounding seals and connections while the appliance is open, as these are often disturbed during replacement.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
