What is the purpose of the curb stop in a water service system?

The primary purpose of a curb stop in a water service system is to isolate the meter for repair. This means that if there are any issues or repairs needed on the water meter, the curb stop allows operators to shut off the water flow to the meter without interrupting service to the entire property. It acts as a control valve located at the boundary of a property, providing a convenient means for maintenance without inconveniencing the homeowner or affecting the water distribution system overall.

While connecting to the city main, measuring water flow, and controlling pressure are important functions in a water service system, they are not directly facilitated by the curb stop. The curb stop does not connect to the city main directly; instead, it functions as a shut-off valve for the service line connected to the main. Additionally, although meters do measure water flow, the curb stop itself does not perform this function. Pressure control is typically managed by other components in the water system. Thus, the focus of the curb stop is specifically on isolating the meter and managing repairs effectively.
