What is the name of the valve that connects a customer's service line to the water main?

The valve that connects a customer's service line to the water main is known as a Corporation Stop. This valve serves a crucial function in the water distribution system; it allows for the control of water flow into a customer's service line from the main supply. Typically installed at the point where the service line intersects with the main water pipeline, the Corporation Stop is essential for isolating a customer's water supply for maintenance or emergency repairs without disrupting the entire water system.

In addition to connecting the service line to the main, the Corporation Stop also facilitates the metering and regulation of water usage. Understanding the role of this valve is important for water distribution professionals, as it directly impacts service reliability and customer satisfaction.
