1. Locate the water supply valve. This is usually located under the sink or behind the toilet. It will be a small, round valve with a handle.
2. Turn the handle clockwise to turn off the water. You should hear a loud “thunk” as the valve closes.
3. Check to make sure the water is off. Turn on the faucet at the sink or toilet and make sure no water is coming out.

What if my toilet is still running after I turn off the water?

1. Check the flapper. The flapper is a rubber disk that sits in the bottom of the toilet tank and seals the hole when the toilet is flushed. If the flapper is damaged or worn out, it may not be sealing properly and water will continue to run into the toilet bowl.

3. Check the fill valve. The fill valve is a small, cylindrical valve that sits in the top of the toilet tank and fills the tank with water after it is flushed. If the fill valve is leaking, it may be causing the toilet to run continuously.
4. Replace the fill valve. You can find replacement fill valves at most hardware stores.
