US 2021/0332897 A1 · POSITIVE STOP FLOW PIPE ISOLATION INSERT

Abstract

A system and method for providing improved water line installation, and more specifically, to a system and method for providing a positive stop flow pipe isolation insert for use in installing water lines to an existing and active main water line is disclosed. The positive stop flow pipe isolation insert includes a water system pipe isolation insert segment connected to mechanical gate valve attached to a water system. The water system pipe isolation insert segment is coupled together with a solid inner core center on its opposite end. A water main pipe isolation insert segment is coupled to the solid inner core center and to the water main pipe on the other. Each of the pipe segments possess a 2″ c.c. threaded hole along a common center line of the pipe segments. A backflow preventer may be attached to the positive stop flow pipe isolation insert using the pair of 2″ c.c. threaded holes to use during pressure testing and chlorination.
