How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 2 of 8
This guide provides verbose step-by-step instructions for replacing a leaky angle stop (shutoff valve) under a sink. The process involves shutting off the main water supply, removing the old compression-style valve from a copper pipe, cleaning the pipe, installing a new quarter-turn ball valve, and checking for leaks.

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.
