Safety Note:: always where safety glasses when cutting or soldering pipe.

1. The first step is to cut out a section of the cold water line to insert the mixing valve. Cut out a small section of both the cold and the hot water lines using a pipe cutter (figure A).

   Note: have a bucket ready to collect any water that is left in the pipes (figure B).

2. Install the 'T' fitting on the hot water pipe.

3. Use the torch and flux to solder it onto the existing hot water line (figure C).

   Note: take off the drain before soldering so that the heat doesn't melt the rubber gasket. After soldering, replace the drain.

4. Use the same soldering technique to attach the stop and waste valves onto the hot and cold supply lines.

   Note: make sure the arrow on the valve points in the direction the water flows (figure D).

5. Now you can turn on the main water supply again.
