The water pipework can be separated in to two 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 pipework within the appliance that carries water to, from and between the various mechanisms of the unit that require it, such as the pump and diverter valve.
