How to Shut Off Bathroom Sink Valve

A leaking bathroom sink valve can waste water and increase your utility bills. Learning how to shut off the valve is a valuable skill for any homeowner. This guide will provide step-by-step instructions to help you safely and effectively turn off the water supply to your bathroom sink.

Identifying the Valve Type

The first step is to identify the type of valve you have. There are two common types:

Compression Valves: These valves have a round handle with a packing nut that tightens to shut off the water.
Cartridge Valves: These valves have a lever handle that pulls up and turns to adjust the water flow and temperature.

Steps to Shut Off Compression Valves

Turn the Handle Clockwise: Most compression valves turn clockwise to close. Gripping the handle, turn it slowly and firmly until it stops.
Tighten the Packing Nut (Optional): If the handle is hard to turn or the valve still leaks, you can try tightening the packing nut. Use a wrench to turn the nut clockwise, but don't overtighten.

Steps to Shut Off Cartridge Valves

Close the Handle: Push down on the lever handle to close the valve completely.
Identify Set Screw (Optional): Some cartridge valves have a set screw that locks the handle in place. If the valve still leaks, you may need to tighten the set screw.
Tighten Set Screw: Use a screwdriver to turn the set screw clockwise until snug. Avoid overtightening.

Additional Tips

Identify the Main Water Shut-Off: In case of an emergency, it's helpful to know where the main water shut-off for your home is located.
Use a Towel: Place a towel under the valve to catch any water that may leak.
Don't Overtighten: Avoid overtightening the valves or nuts, as this can damage the valve or seals.

By following these instructions, you can safely and effectively shut off the water supply to your bathroom sink. If you encounter any issues or the leak persists, consult a licensed plumber.
