What type of shutoff valve is commonly known as a "Corporation" stop?

The term "Corporation stop" refers to a specific type of shutoff valve that is typically installed on water service lines at the point where the main line enters a property. This valve is generally used to control the flow of water from the municipal water supply into a building's plumbing system.

What distinguishes a Corporation stop is its connection method; it is directly attached to the water main, often via a corporation stop fitting, providing a reliable shutoff point for maintenance and emergencies. This valve type allows utility companies or plumbers to isolate water flow without needing to shut off the entire distribution system.

Understanding the function and application of Corporation stops is crucial for plumbing professionals, especially when it comes to installation, repair, or replacement tasks. Knowledge of such valves facilitates better service and maintenance in plumbing systems, ensuring efficiency and reliability in water delivery.
