Which of the following is NOT true about the corporation stop?

The statement that it isolates the meter for repairs is not true about the corporation stop. A corporation stop is a fitting that connects the water service line to the city main. Its main purpose is to allow operators to control the flow of water from the main line into the service line, essentially managing the water supply.

The correct functioning and installation of a corporation stop means it is typically located at the point where the service line connects to the main, which is before any meter that measures usage. Therefore, while it does facilitate control over the water supply and connects to the city main, it does not serve the purpose of isolating the meter for repairs; that task is typically managed by the curb stop or shut-off valve. This distinction is vital for understanding the different components in a water service system and their functions.
