Worcester Pipe Assembly (Page 10)
The water pipework can be split in to 2 categories. The first would be the pipes that allow an influx of water in to the heating unit. This would include the mains water supply and the water pipework on the wall jig. The second category would be the pipes within the appliance that are responsible for carrying water from, to and between the different parts of the unit that require it, such as the pump and diverter valve.
