How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 4 of 8
In this video
After ensuring the main water supply is off, use channel lock pliers to unscrew the braided washing machine hoses from the old valves by turning the fittings counter-clockwise. Next, use two wrenches for leverage and stability: one pipe wrench to grip and hold the pipe inside the wall box stationary, and a second pair of large channel lock pliers to grip the body of the old valve. Turn the valve counter-clockwise to unscrew it from the pipe fitting. This may require considerable force if the valve is old and corroded.
Goal: Safely remove the existing washing machine valves from the wall pipes.
- Using a backup wrench on the pipe is crucial to avoid damaging the plumbing inside the wall.

- Channel Lock Pliers (Pliers Type: Slip-joint, Adjustable Wrench Size: 10-inch, Tool Material: High Carbon Steel) — Gripping and turning the old and new valves, as well as disconnecting the supply hoses.
- Pipe Wrench (Adjustable Wrench Size: Medium (8), Tool Material: High Carbon Steel, Mechanism: Sliding) — Holding the water pipe steady inside the wall to provide counter-torque and prevent the pipe from twisting or breaking.

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.
