What kind of valve do you use to shut off water?

They are most commonly used in applications where the water needs to be shut off only infrequently. Ball valves are perhaps the most reliable type of valve and are commonly used for main water shutoffs and for branch line shutoffs.

Ball Valve. Ball valves are perhaps the most reliable type of valve and are commonly used for main water shutoffs and for branch line shutoffs.
