ABSTRACT:
An in-line water shut-off valve is provided including a tailpipe which is attached to a main water line in order to form a “T” or 90° “L” which protrudes from the wall of the building and upon which is attached a cap which is threadably and rotatably attached and includes a plug therein so that upon rotation into a closed position, the plug will block the through flow bore of the tailpipe. After the installation of fixtures, the water supply line of the fixture may be threadingly attached to an outlet of the cap and the cap rotated 180 degrees to open the valve in order to allow for the flow of water; without the need of cutting off and replacing caps, soldering additional caps or valves or turning off the main water supply.
