How to Turn Off the Water to Your Bathroom Sink Faucet
Before performing any repairs, make sure you know how to turn off water to your bathroom sink faucet by using the shut-off valves located under the sink. Shutting off the water to your bathroom sink faucet is simple. Most bathroom 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:
- Locate the Shut-Off Valves
Open the cabinet doors beneath your bathroom 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. - 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.
- Check for Water Flow
Once both valves are off, turn on the faucet to ensure no water flows. 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 shut-off valves under the sink may be hard to turn or may not be there at all. Here are some solutions:
- Shut Off the Main Water Supply
If you can’t turn off the sink valves, your next option is to turn off the water to your entire home. For help with this, check out our Master Guide: How to Turn Off Water to Your Whole House. - Call a Plumber
