Install and Tighten New Valve — Install the New Angle Stop

How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 6 of 8
In this video
Place the valve body back onto the pipe, over the taped ferrule. Thread the compression nut on by hand until it is finger-tight. Then, using the two-wrench method again, hold the valve body stationary while tightening the compression nut until it is very snug. Do not over-tighten. Finally, make sure the handle on the new valve is turned to the 'off' position.
Goal: Secure the new valve in place
- Hold the valve body still to prevent it from rotating and stressing the Teflon tape while you tighten the nut.
- Ensure the valve is closed before turning the main water back on.

FAQs
This project is listed as 'beginner' difficulty, but involves water shut-off. Is it truly manageable for someone with no plumbing experience?
Yes, this project is very manageable for beginners provided you follow the steps carefully and patiently. The key is to ensure the main water supply is completely off before starting. Take your time, read all instructions before beginning, and don't hesitate to consult online videos if a step feels unclear.
What should I do if I can't locate or shut off my home's main water supply valve?
Locating and properly operating your main water shut-off valve is critical before starting. If you can't find it or it's stuck, do not force it. In such cases, it's best to contact a qualified plumber to assist with the shut-off or perform the repair to avoid potential major water damage.
The guide mentions installing a 'quarter-turn ball valve.' Why is this type recommended over a traditional multi-turn compression valve?
Quarter-turn ball valves are highly recommended because they offer superior durability and reliability. They are less prone to leaks over time and operate with a simple 90-degree turn, making them much easier to use and less likely to seize up than older multi-turn compression valves, especially in an emergency.
After installing the new angle stop and turning the water back on, what are the most common reasons it might still leak, and how do I fix them?
Common leaks usually stem from improper compression of the ferrule, a damaged ferrule, or a connection that isn't tight enough. Ensure the compression nut is snugly tightened (but not overtightened) and that the ferrule is correctly seated. If using a new supply line, confirm the washers are properly installed and the connection is secure.
