The water pipework can be split in to two categories. The first would be the pipes that enable water to be fed 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 devices of the unit that require it, such as the pump and diverter valve.
