In this guide, we’ll walk you through how to shut off the water supply to your kitchen sink, the tools you’ll need, and provide links to related fixture shut-off guides.
Why You Might Need to Turn Off the Water to Your Kitchen Sink
Turning off the water to your kitchen sink is useful for a variety of situations, including:
- Fixing a leaky faucet
- Installing a new sink or faucet
- Replacing water supply lines
- Preventing water damage in case of a leak
Tools You’ll Need:
- Adjustable Wrench (for tightening or loosening water supply connections)

How to Turn Off the Water to Your Kitchen Sink
Turning off the water to your kitchen sink is relatively straightforward. Most sinks have two shut-off valves located underneath the sink, one for hot water and one for cold. Here’s a step-by-step guide on how to do it:
1. Locate the Shut-Off Valves
Open the cabinet doors under your kitchen sink. You should see two small valves connected to the water supply pipes—one for cold water and one for hot water. These valves are typically small round knobs or lever handles.
2. Turn the Valves Off
- To turn off the cold water, rotate the cold water shut-off valve clockwise until it stops.
- To turn off the hot water, rotate the hot water shut-off valve clockwise until it stops.
Pro Tip: If the valve is difficult to turn, use an adjustable wrench to get more leverage. Be cautious not to over-tighten, as this could damage the valve.
3. Check for Water Flow
Once you’ve turned both valves off, turn on the faucet to ensure the water has stopped flowing. If no water comes out, you’ve successfully shut off the water supply.
What to Do If You Can’t Find or Turn Off the Valves
In some older homes, the valves under the sink may be stuck or hard to turn, or they may not be there at all. Here are a few solutions:
1. Shut Off the Main Water Supply
If you can’t turn off the sink valves, you may need to turn off the water to the entire house. For help with this, check out our Master Guide: How to Turn Off Water to Your Whole House.
2. Call a Plumber
If the shut-off valves are damaged or won’t budge, it’s best to call a professional plumber. They can repair or replace the valves to ensure they work properly in the future.
