Safety First: Precautions to Take

Before embarking on this project, ensure your safety by following these precautions:

• Shut off the main water supply to your home.
• Open faucets to relieve any residual water pressure.
• Wear safety glasses and gloves to protect yourself from splashes and sharp edges.

Step-by-Step Guide to Changing an Angle Stop Valve:

1. Locate and Identify the Angle Stop Valve

Identify the fixture you’re working on and trace the water supply line to the nearest angle stop valve. It’s typically located behind the fixture or under the sink.

2. Shut Off the Angle Stop Valve

Turn the handle of the angle stop valve clockwise to shut off the water supply to the fixture. If the handle is stuck or difficult to turn, use an adjustable wrench to gently loosen it.

3. Disconnect the Supply Line

Use a basin wrench to loosen the nut that connects the supply line to the angle stop valve. Be careful not to overtighten or damage the nut.

4. Remove the Old Valve

Once the supply line is disconnected, use an adjustable wrench to unscrew the old angle stop valve from the water pipe. Apply gentle pressure to avoid damaging the threads.

5. Apply Plumber’s Putty

Apply a small amount of plumber’s putty to the threads of the new angle stop valve. This will create a watertight seal.

6. Install the New Valve

Screw the new angle stop valve onto the water pipe by hand until it’s finger-tight. Then, use an adjustable wrench to tighten it further, but be careful not to overtighten.

7. Reconnect the Supply Line

Tighten the nut that connects the supply line to the angle stop valve using a basin wrench. Ensure the connection is secure but not overly tight.

8. Turn on the Water Supply

Slowly turn on the main water supply and check for leaks. If you notice any leaks, tighten the connections as needed.

Tips for a Successful Valve Replacement:

• Use Teflon tape on the threads of the new valve and supply line for added leak protection.
• If the old valve is particularly stubborn, apply penetrating oil to loosen it.
• If you’re replacing an angle stop valve under a sink, use a flashlight to illuminate the work area.
• If you’re unsure about any step, don’t hesitate to consult a licensed plumber.

Common Problems and Solutions:

• Leaking valve: Tighten the connections or replace the O-rings inside the valve.
• Stuck handle: Replace the handle or the valve seat.
• Corrosion: Replace the valve if it’s severely corroded.
