What it is
The Worcester Bosch Pipe - Return Top is a formed pipe section for the return side of the boiler's water circuit. It is supplied by Worcester Bosch for the Greenstar appliance family, where it routes return water through the top section of the heat exchanger assembly. The pipe is a shaped metal component with the connection points needed to seat into the return path.
Signs this part needs replacing
- Visible corrosion, pitting or scaling on the pipe wall or around the joints
- Weeping or tracked water staining at the pipe unions or along the pipe run
- Boiler losing pressure repeatedly with no other obvious source of loss
- Overheating or poor return flow traced to a restricted or blocked return pipe
- Kettling or noise from the heat exchanger linked to reduced return flow
Before you order
- Confirm the appliance model against the fit list, as the LPG variant is specified here
- Check the existing pipe for damage and confirm the fault is on the return top section rather than another part of the circuit
- Have the appliance isolated, drained and safe to work on before removing the old pipe
- Check the pipe unions and seals for condition, as these are not part of this item
