Install the Shutoff Valve
Install the shutoff valve on the nearest frequently used drinking water line.
1
Choose a location for the valve that is easily accessible. It is best to connect
2
into the side of a vertical water pipe. When it is necessary to connect into a
horizontal water pipe, make the connection to the top or side, rather than at
the bottom, to avoid drawing off any sediment from the water pipe.
Drill a 1/4" hole in the water pipe, using a sharp bit. Remove any burrs
3
resulting from drilling the hole in the pipe.
Fasten the shutoff valve to the cold water pipe with the pipe clamp.
4
Tighten the clamp screws until the sealing washer begins to swell.
5
Do not overtighten or you may crush the copper tubing.
