How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 7 of 10
In this video
Slide the compression nut and the new ferrule over the end of the flexible pipe. Insert the pipe into the fitting body and slide the nut down to the threads. Hand-tighten the nut as much as possible. Then, using an adjustable wrench, tighten the nut an additional one-half to one full turn to compress the ferrule and create a seal.
Goal: Secure the flexible pipe to the new fitting
- Do not overtighten the compression nut, as this can damage the fitting or crush the pipe.

FAQs
Is the 3-hour time estimate realistic for a beginner attempting this for the first time?
For a beginner, the 3-hour estimate is achievable, but it's wise to budget an extra hour or two, especially if you encounter corroded parts or need to double-check steps. Taking your time to ensure proper installation is key to preventing future leaks and avoiding costly mistakes.
What are the most common mistakes beginners make when replacing an angle stop, and how can I avoid them?
Overtightening the compression nut is a frequent error that can damage the pipe or ferrule, leading to leaks. Always use two wrenches—one to hold the valve body and one to tighten the nut—and tighten until snug, then an additional quarter to half turn. Not fully cleaning the pipe stub-out is another mistake; ensure it's smooth and free of debris for a good seal.
Do I really need all the specific tools listed, or can I make do with a basic adjustable wrench and pliers?
While an adjustable wrench and tongue-and-groove pliers are essential, specialized tools like the Angle Compression Stop Wrench can make working in tight spaces much easier and prevent stripped nuts. For a beginner, having the right tools improves efficiency and reduces the likelihood of issues. Consider borrowing or renting specialized tools if you don't want to purchase them for a one-time use.
What are the crucial safety precautions to take before starting this project, particularly regarding water shut-off?
The most critical step is completely shutting off the main water supply to your house. Verify this by opening a lower-level faucet after shutting off the main to ensure the water flow stops completely. Also, ensure you have plenty of towels and a bucket ready to catch any residual water from the pipes to prevent water damage under the sink.
