How to Install Shut-Off Valves
Shut-off or stop valves come in a variety of combinations for connecting water supply lines to your fixtures. Learn how to install shut-off valves in this video by The Home Depot:
You will need the following tools and materials:
- Adjustable wrenches
- Tube cutter or hand saw
- Flashlight (optional)
- Compression fittings
- Shut-off valves
- Emery cloth
- Cloths/rags (optional)
1. Drain supply line: After turning off the main water supply into the home, open the faucet to drain the line.
2. Cut supply line: Cut the old supply line, leaving enough space between the escutcheon plate and the cut to allow installation of the new fitting. Avoid bending the pipe while cutting as it can cause a leak.
3. Add compression nut: Slide the compression nut over the supply pipe as far back as you can to give yourself room to work, then use an emery cloth to remove any rough edges.
4. Insert compression ring: Place the compression ring over the end of the supply pipe. The ring, or ferrule, should completely cover the end of the pipe.
5. Thread compression valve: Slide the new valve squarely and snugly over the ring and thread it onto the nut, tightening by hand. If nuts are hard to turn, use a bit of oil instead of pipe compound, which can cause leaks.
6. Tighten compression valve: To finish tightening the nut, use one wrench to hold back the valve while
keeping it square. Use your second wrench to turn the nut. Avoid overtightening the valve as it can cause leaks. Connet the other water line in the exact same manner.
7. Re-attach supply lines: Follow the same process to attach and tighten the existing supply lines from the fixture to the new valves. Remove old supply lines before replacing with new flexible lines.
8. Check for leaks: After turning the main water supply back one, open the new valves. After turning on the faucet to clear the air from the lines, check your new valves for leaks. If a leak is present, tighten the joints until sealed.
