Locate The Shut-off Valves
Shut-off valves control the water flow to the kitchen sink. Usually, they are located under the sink cabinet. Look for two small valves, one for hot water and one for cold water.
These valves often have round or oval handles. Turning them clockwise will stop the water. Sometimes, valves might be behind the cabinet or under the sink pipes. Check carefully to find them.
- Turn the handles slowly to avoid damage.
- Make sure both valves are fully closed.
- If no valves are visible, the main water shut-off may be needed.

Turn Off The Main Water Supply
Locate the main water valvein your home. It is often near the water meter or where the main pipe enters the house. Turn the valve clockwiseto close it. This will stop all water flow to the kitchen sink and other parts of your home.
Check if the water is off by opening the kitchen sink faucet. No water should come out. If water still flows, try turning the valve more tightly.
Some homes have a shut-off valveunder the kitchen sink. Turn this valve clockwise to stop water only to the sink, not the whole house.
Drain The Remaining Water
Open the faucet to let all the water drain out. This stops any water left in the pipes from causing leaks. Use a bucket to catch water if needed. Keep the faucet open until no more water flows out.
Check under the sink for any water drops. Wipe them with a cloth to keep the area dry. This helps prevent mold or damage.
- Turn off the main water valve first.
- Open the sink faucet fully.
- Let water drain completely.
- Dry the sink area thoroughly.
