Connect the Copper Tubing — Install the New Angle Stop
Part of project
How to Replace a Leaky Angle Stop (Shutoff Valve) Under Your Sink · Step 7 of 9
In this video
Prepare the new copper tubing by ensuring the end is clean and smooth; file it if necessary. Slide the compression nut onto the tubing, followed by the brass ferrule (compression ring). Insert the end of the tubing fully into the outlet port on the saddle valve. Slide the nut and ferrule down and hand-tighten the compression nut onto the valve. Finally, use a crescent wrench to tighten the nut about one full turn past hand-tight to create a secure, leak-proof connection.
Goal: Attach the new water line to the saddle valve
- Do not crimp or bend the copper tubing at a sharp angle, as this can restrict water flow or cause a weak point.

FAQs
What's the single most important safety step to take before I even touch the leaky angle stop?
The most critical step is to shut off the main water supply to your home. This prevents potential flooding and ensures a safe working environment. Always confirm the water is off by testing a nearby faucet before proceeding with any work.
The project is listed as 'beginner' difficulty, but 3 hours seems long for a valve. Is it really that involved?
While replacing an angle stop is beginner-friendly, the 3-hour estimate accounts for prep work like gathering tools, draining lines, dealing with potential seized parts, and thorough leak testing. Taking your time ensures a proper, leak-free installation, so don't rush the process.
I see "Adjustable Wrench" and "Tongue and Groove Pliers" listed. Are these specific tools essential, or can I get by with a generic wrench set?
Yes, these specific tools are highly recommended. An adjustable wrench helps securely tighten the compression nut on the new valve without stripping it, while tongue and groove pliers (like Channellock) provide a strong grip for holding the valve or pipe steady. Using the correct tools prevents damage and ensures a tight, leak-free connection.
This project specifically mentions installing a "compression-style valve." Are there other types of angle stops, and why is this type recommended for a DIYer?
Yes, other types include soldered (sweat) and push-to-connect (SharkBite) valves. Compression-style valves are ideal for DIYers because they create a watertight seal by compressing a ferrule onto the pipe, requiring only basic hand tools and no specialized skills like soldering, making them relatively easy to install.
