What is a curb stop?

Understanding Your Water System

A curb stop is the valve that the utility uses to turn your water service on or off, located inside the keybox at your property line.


A curb stop is the valve that controls whether water flows from the utility’s system to your property. The utility uses this valve to turn your water service on or off when needed.

Key points about curb stops:

When the utility “discontinues” service, they turn off the curb stop valve at the keybox. When they “disconnect” service, they physically disconnect the service connection, usually at the main water line. Discontinuance is temporary and easier to restore; disconnection is more serious and costly.
