Where is a shut-off valve typically located?

A shut-off valve is typically located close to the fixture it controls because this positioning allows for easy access in case of emergencies or maintenance needs. By placing the shut-off valve near the fixture, it enables quick isolation of the water supply for tasks such as repairs or replacements without affecting the entire plumbing system of the house. This accessibility is crucial in kitchens, where leaks can lead to significant damage or water waste.

While other locations may also have shut-off valves, such as the main water supply line or underneath the kitchen sink, the primary function of a shut-off valve is to provide immediate control over water flow directly at the point of use. Therefore, the most logical and practical placement is in close proximity to the fixture itself.
