How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 6 of 7
In this video
Using an adjustable wrench, give the supply line connections at the shut-off valves a final quarter-turn to ensure they are snug. Slowly turn the shut-off valve handles counter-clockwise to turn the water back on. Check all connections for any leaks. Finally, turn on the new faucet to test for proper water flow and to flush any debris from the lines.
Goal: Finalize installation and verify functionality
- Turn the water on slowly. This reduces the risk of a high-pressure spray if a connection is loose.

FAQs
What's the absolute first thing I should do to ensure safety and prevent water damage before starting?
The most critical first step is to shut off the main water supply to your house. After that, open the nearest faucet (or the faucet above the angle stop you're replacing) to drain any residual water from the lines and relieve pressure, minimizing spills during the replacement.
Is this project genuinely suitable for a beginner, and is the 3-hour estimate realistic for someone new to plumbing?
Yes, this project is considered beginner-friendly as it doesn't require advanced plumbing skills like soldering. The 3-hour estimate is realistic, accounting for preparation, potential challenges like corroded parts, careful installation, and thorough leak checking, which is crucial for a successful outcome.
Do I really need all the specialized wrenches and pliers listed, or can I manage with basic tools?
While an adjustable wrench is essential, the Channellock pliers (like the 12 in. V-Jaw Tongue and Groove) are highly recommended. They provide superior grip, especially on older, potentially rounded or stuck nuts, preventing frustration and potential damage. A good flashlight is also invaluable for seeing into tight, dark spaces under a sink.
What's the most common mistake beginners make that leads to leaks after installing the new angle stop?
The most common mistake is improper installation of the compression fitting. Ensure the pipe stub-out is clean and smooth, and the compression nut is tightened correctly. Tighten it firmly by hand, then use a wrench for another 1/2 to 3/4 turn – overtightening can crush the ferrule, while undertightening will leak.
