What type of stop valve is typically used in water service lines?

The corporation stop is specifically designed for use in water service lines to connect the water main with the service line that runs to a building or property. This type of valve is installed directly in the water main and allows for the control of water flow to the service line. It is particularly favored because it can be operated under pressure, meaning that water service can be maintained while the valve is being accessed or worked on.

Corporation stops are crucial for connection points, facilitating the distribution of water supply from municipal sources to individual properties. They ensure that service can be initiated or terminated without interrupting the entire supply from the main line, making it essential for efficient water management in urban and suburban systems.

Other types of valves, while they serve important functions, do not fulfill this specific role as effectively. For example, curb stops are typically located at the property line and provide a means to shut off service to the entire property. Meter stops are used at the meter connection to allow for the maintenance or replacement of the meter but do not serve as the initial connection to the water main. Meanwhile, gate valves are commonly employed in larger pipe systems to control flow, but they are not the primary type used for direct connections in service lines. Thus, the corporation stop stands out
