What is a corp stop?

A corp stop refers to a shut-off valve that is typically installed at the main water supply line. It is used to control the flow of water in a system, allowing maintenance work to be performed on water mains or service lines without having to shut off the water supply to an entire area. This is crucial for repairs or when new connections to the water system are being made. The corp stop is usually accessed through a corporation valve and is fundamental in ensuring that water service remains uninterrupted to as many customers as possible while necessary maintenance is carried out.

The other choices do not pertain to the definition of a corp stop. A water filter serves a different function of purifying water, while water pollution control methods deal with environmental concerns, and temperature control mechanisms are unrelated to the function of a shut-off valve in water systems.
