What it is
The tank flow pipe, part number 87186804560, is a Worcester Bosch component used on Greenstar Highflow 440CDi and 550CDi appliances. It forms part of the pipework run between the tank and the boiler, carrying water through the flow side of the circuit. Replacement is normally required when the existing pipe is damaged, corroded or leaking at a joint.
Signs this part needs replacing
- Visible water weeping or staining along the pipe or at its connections
- Corrosion, pitting or surface scaling on the pipe wall
- A joint that will not seal after re-making
- Reduced flow through the tank circuit, with the boiler cycling or cutting out
- Physical damage, kinking or deformation of the pipe
Before you order
- Confirm the appliance model and whether it is an ErP version, as listed in the fitment data
- Check the existing pipe for visible damage so the correct section is replaced
- Verify the part number 87186804560 against the marking on the component being removed
- Isolate the water supply and depressurise the system before any work begins
