How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 4 of 8
In this video
After removing the valve, slide the old compression nut off the copper pipe. The small brass ring, called a ferrule, will likely remain on the pipe. Use pliers to grip the ferrule and pull it off. If it is stuck, a special ferrule puller tool can be used. Ensure the end of the copper pipe is clean and smooth before proceeding.
Goal: Plumbing Pipes Repair
- If the ferrule is very stuck and you don't have a puller, you may need to cut the pipe just behind the ferrule, but only if you have enough pipe length remaining.

FAQs
How difficult is it to replace an angle stop, and how long does it typically take for a beginner?
This project is rated as 'beginner' difficulty, making it accessible for most DIYers. While shutting off water and working in tight spaces requires attention, the steps are straightforward. Expect to spend around 3 hours, which includes time for preparation, troubleshooting, and thorough leak testing.
What are the most important safety precautions I need to take before starting this plumbing repair?
The most critical step is to shut off the main water supply to your house to prevent potential flooding. Always have a bucket and plenty of absorbent towels like WYPALL L40 or ITOPFOX paper towels readily available for draining residual water and catching any spills. Good lighting, such as the Panther Vision FLATEYE flashlight, is also essential for working under the sink.
Do I really need specialized plumbing tools for this project, or can I get by with basic household tools?
While some tools listed are general, an adjustable wrench and quality tongue-and-groove pliers (like Channellock 430) are essential for securely tightening and loosening plumbing connections. These specialized tools provide the necessary grip and leverage to prevent stripping fasteners or damaging pipes, which household tools might struggle with.
What's the most common reason for a new angle stop to leak after installation, and how can I prevent it?
The most common reason for a leak is improper tightening of the compression nut or an uneven/burred pipe end. Ensure the copper pipe is clean and smooth, free of any imperfections, before sliding on the new compression components. Tighten the compression nut firmly with an adjustable wrench, but avoid overtightening, as this can damage the ferrule; a slight weep often just needs another quarter turn.
