Waterproofing your home: how to replace an angle stop valve like a pro

Replacing an angle stop valve is a relatively simple plumbing task that can be completed in under an hour. An angle stop valve is a small valve that controls the flow of water to a specific fixture, such as a sink, toilet, or washing machine. Over time, angle stop valves can become worn or damaged, leading to leaks or reduced water pressure. If you’re experiencing any issues with your water fixtures, it’s worth checking the angle stop valve to see if it needs to be replaced.

Tools and Materials You’ll Need

Before you start, gather the following tools and materials:

• New angle stop valve
• Adjustable wrench
• Basin wrench
• Plumber’s putty
• Teflon tape
• Utility knife
• Rags

Step-by-Step Instructions

1. Turn Off the Water Supply

The first step is to turn off the water supply to the fixture that you’re working on. This is typically done by turning the main water valve off. If you don’t know where your main water valve is, check with your local building code or contact a plumber.

2. Open the Fixture

Once the water supply is turned off, open the fixture to release any remaining water pressure. This will help prevent water from spraying out when you remove the angle stop valve.

3. Remove the Old Angle Stop Valve

Using an adjustable wrench, loosen the packing nut that connects the angle stop valve to the water supply pipe. Once the packing nut is loose, you can use a basin wrench to remove the angle stop valve from the pipe.

4. Clean the Connection

Once the old angle stop valve is removed, clean the connection on the water supply pipe using a rag and some rubbing alcohol. This will help ensure a good seal when you install the new angle stop valve.

5. Apply Plumber’s Putty

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

6. Wrap Teflon Tape

Wrap the threads of the new angle stop valve with Teflon tape. This will further help to create a watertight seal.

7. Install the New Angle Stop Valve

Hand-tighten the new angle stop valve onto the water supply pipe. Once it’s hand-tight, use an adjustable wrench to tighten it further. Be careful not to overtighten the valve, as this could damage the valve or the pipe.

8. Turn On the Water Supply

Once the new angle stop valve is installed, turn on the water supply and check for leaks. If you see any leaks, tighten the packing nut further until the leak stops.

9. Reattach the Fixture

Once the new angle stop valve is installed and leak-free, reattach the fixture to the water supply pipe.

Troubleshooting

If you’re having trouble replacing an angle stop valve, here are a few troubleshooting tips:

• The valve is leaking. If the valve is leaking, it’s possible that the packing nut is not tight enough. Tighten the packing nut further until the leak stops.
• The valve is difficult to turn. If the valve is difficult to turn, it’s possible that the valve is damaged or that there is debris in the valve. Try to clean the valve with some rubbing alcohol and a toothbrush. If the valve is still difficult to turn, you may need to replace it.
• The valve is not working. If the valve is not working, it’s possible that the valve is defective. Try replacing the valve with a new one.

Final Thoughts

Replacing an angle stop valve is a relatively simple plumbing task that can be completed in under an hour. By following these steps, you can easily replace an angle stop valve and get your water fixtures working properly again.

Answers to Your Questions

Q: How often should I replace an angle stop valve?
A: Angle stop valves should be replaced every 5-10 years, or more often if they are leaking or damaged.

Q: Can I replace an angle stop valve without turning off the water supply?
A: No, you should always turn off the water supply before replacing an angle stop valve.

Q: What is the difference between an angle stop valve and a gate valve?
A: Angle stop valves are designed to be used in tight spaces, while gate valves are designed to be used in larger spaces. Angle stop valves also have a quarter-turn handle, while gate valves have a multi-turn handle.

Q: Can I use a regular wrench to replace an angle stop valve?
A: No, you should use an adjustable wrench or a basin wrench to replace an angle stop valve. Regular wrenches can damage the valve or the pipe.

Q: What should I do if the angle stop valve is stuck?
A: If the angle stop valve is stuck, you can try to loosen it using a penetrating oil. If the valve is still stuck, you may need to call a plumber.
