What it is
This is a pipe supplied by Worcester Bosch under part number 8716121861. It is listed for use in the Worcester Greenstar 4000 System and Greenstar Gr4700IW System appliance families. The pipe carries water or flue-side media as part of the appliance's internal pipework assembly, depending on the position it occupies in the boiler.
Signs this part needs replacing
- Visible weeping or pooling of water at the pipe or its connections
- Corrosion, pitting or surface staining on the pipe wall
- Scale or debris build-up restricting flow through the pipe
- Discolouration or distortion suggesting the pipe has been overheated
- A joint that will not seal after the connection has been remade
Before you order
- Confirm the boiler model and GC number from the appliance data badge against the fit list above
- Check part number 8716121861 against the appliance's own parts listing to confirm this is the pipe required
- Identify the exact pipe position in the assembly, as more than one pipe is used on these appliances
- Check the condition of any seals, washers or olives at the connection and order them separately if needed
