The water pipework can be split 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 pipes inside the appliance that are responsible for carrying water to, from and between the numerous elements of the unit that require it, such as the heat exchanger and pump.
