Copper zinc water filtration is a high-purity brass water filtration process that relies on the redox potential of dissolved oxygen in water in the presence of a zinc anode and copper cathode. It uses dissolved impurities within water as constituent substrate, which are reduced to more physiologically inert compounds.

One part of the system is the connections between the water mains and the water user locations. A service line is a pipe that makes the connection, which was also made of lead in those days. The first portion of the service line is called a gooseneck, which connects to a valve at the water main and is required to be flexible to allow some movement.
