What is the primary function of a curb cock?

The primary function of a curb cock is to control the flow of potable water into a building. This valve is typically located at the property line, where the water supply enters a building, and is crucial for managing the water supply. It allows for the isolation of the building's water system from the municipal water supply, enabling maintenance work or emergency shut-off without disrupting water service to neighboring properties.

Controlling the flow of potable water is vital for ensuring the safety and functionality of the water supply within a building. In the event of a plumbing issue or repairs that need to be performed, the curb cock allows for a quick and efficient way to stop the water flow, preventing potential water damage or other risks associated with leaks or burst pipes.

While isolating different plumbing systems is important, it is a secondary function. The curb cock's main and most immediate role is to control the entry of water, making it an essential component in maintaining the integrity and safety of a building's water supply system.
