How To Shut Off Water Under Sink

A leaky faucet or running toilet can waste a lot of water and money. If you need to make repairs, you'll need to know how to shut off the water under the sink. It's a simple process that can be done in just a few minutes.

**Step 1: Locate the shut-off valves.**

The shut-off valves are usually located under the sink, near the base of the faucet. They are typically small, quarter-turn valves. If you can't find the valves, consult your sink's manual or look for them in the cabinet below the sink.

**Step 2: Turn off the water supply.**

Once you've located the shut-off valves, turn them off by turning them clockwise. You should feel them tighten as you turn them.

**Step 3: Check for leaks.**

After you've turned off the valves, check for leaks. Open the faucet and look for any water coming out of the valve or the faucet itself. If you see any leaks, tighten the valves until the leak stops.

**Step 4: Turn on the water supply.**

Once you're sure that there are no leaks, turn the water supply back on by turning the valves counterclockwise. You should feel them loosen as you turn them.

**Tips:**

If you're not sure which valve controls the water supply to your sink, turn off both valves.
If you're having trouble turning the valves, use a pair of pliers.
If you're not comfortable shutting off the water yourself, call a plumber.
