An Overview of Corporation Stops
Corporation stops are specialized valves used in water distribution systems to control the flow of water between the main water supply line and individual service lines. They’re commonly made from materials such as brass or bronze and are designed to be durable and resistant to corrosion — ensuring long-lasting performance even in harsh environments. Corporation stops are installed using a process called tapping, which involves creating a threaded connection on the main water line without interrupting the water flow. This allows for the seamless integration of new service lines or the replacement of old ones with minimal disruption to the overall system.
Corporation stops are available in various sizes and thread types to ensure that they are compatible with different pipe diameters. In addition to controlling water flow, they also serve as an important safety measure by providing a means to shut off the water supply to a specific property in the event of a leak or other emergency.

Why Corporation Stops Are Important
Corporation stops are vital components in water distribution systems, providing a multitude of benefits that ensure the safe and efficient delivery of water to residential, commercial, and industrial properties. One of the key advantages of corporation stops is their ability to control water flow between the main water supply line and individual service lines, enabling maintenance work, repairs, or replacements without interrupting the water supply for other users. This helps reduce disruptions and contributes to the overall reliability of the system.
Corporation stops also help prevent backflow and contamination of the main water supply, helping to protect its integrity. As a result, corporation stops play an indispensable role in modern water distribution networks by offering reliable connections, facilitating maintenance and repairs, and safeguarding the quality of the water supply.
