초록 ▼

A method is provided for attaching a water shut-off control valve to a predetermined position on a water distribution pipe, such as, for example, an installed service pipe, without stopping the passage of water therethrough wherein a T-pipe is attached to the damaged water distribution pipe, a first valve assembly is then mounted on the T-pipe assembly, a hole boring assembly is mounted on the free end of the first valve assembly in watertight relation therewith, and a hole then bored into the water distribution pipe and the hole is closed by the first valve member after which the boring assembly is withdrawn. A second valve assembly having an external housing is mounted to the free end of the first valve assembly by means of the external housing and the valve seat of the second valve housing then inserted through the opening and the water distribution pipe locked in place to shut off the flow of water through either distribution pipe and the external housing is thereafter removed. The present invention includes apparatus for carrying out the method.
