What is the primary function of a corporation stop in a service tap setup?

The primary function of a corporation stop in a service tap setup is to start and stop water flow. A corporation stop is typically installed in conjunction with service lines that connect the main water supply to the individual customer's service line. This valve allows operators to control the water flow to a property, making it possible to turn the water on or shut it off for maintenance, repairs, or in emergencies.

While other functions like regulating pressure, measuring flow, and preventing backflow are crucial in water distribution systems, they are performed by different components such as pressure regulating valves, flow meters, and backflow prevention devices. The corporation stop specifically provides the essential function of controlling direct water delivery to service lines.
