Turn off the main water supply and cut off the end cap of the copper water line, leaving enough pipe exposed so the shut-off will fit properly. If the valve is set too deep in the ground for you to access it, you may need to call the water company to come and do this for you. Step 2. Find the place in the basement or crawl space where the main water supply enters the house and connects with the plumbing. You may find a fitting that connects the 3/4- inch copper pipes of the house plumbing to the incoming water supply. Step 3. Choose an easy- to- reach place at least 1 foot away from this fitting, and cut the copper pipe with a pipe cutter. Tighten the cutter onto the pipe by turning the nut clockwise, and swivel the cutter completely around the pipe. Tighten the nut a little more and swivel again. Repeat until the pipe separates, then let the water drain into a bucket. Finally, cut an extra inch from the end of one of the pipes to make room for the valve. Step 4.

Heat one end of the valve with a propane torch until the solder begins to spit and smoke, then remove the flame and touch the end of a coil of lead- free solder to the joint. Move the solder completely around the valve as the solder melts and wicks into the gap between the pipe and the valve. Solder the other side of the valve in the same way. Step 6. Keep the valve open while you turn the water back on at the street. Check the connections and verify that there are no leaks. Installing Angle Stops. Step 1. Unscrew the compression nut from the inlet for the toilet or faucet and remove the brass ring inside. Slide the nut along the water inlet pipe in the wall, and then fit the ring around the end of the pipe and slide it about 1/4 inch along the pipe. Step 2. Fit the threaded inlet of the angle stop onto the end of the pipe until it meets the ring and slide the nut back down the pipe to contact the valve. Screw the nut onto the valve by hand, and then tighten it with channel- locking pliers. Step 3. Turn on the main water supply and check for leaks. If the fitting leaks, remove it, wrap Teflon tape around the threaded end of the valve, and tighten it back onto the pipe. Warnings. Be sure all the water is out of the pipes before you try to sweat on a valve. It is a good idea to open several taps in the house to help water drain and to keep these open while you are soldering so that steam has a way to escape. References.
