Profile: Legacy Valve LLC offers services to prevent unwanted shutdowns & keep critical service lines operational during tie-ins, relocations, and repairs. Insta-Valve® eliminates many of the problems commonly associated with valve insertion and valve replacement. Installing Insta-Valve® can eliminate complicated planning for system shut down. It is a highly reliable, easy-to-install and easy-to-use trouble free valve replacement system. This new system installs a flow control valve into a pressurized line without the interruption of existing service. Line stopping can eliminate costly and dangerous system shutdowns. It is the process of installing a temporary flow control plug into a pressurized line to stop the flow of water. A line stop enables a pipe line to be isolated for repairs or additions without causing an interruption in service. Wet tapping is a very effective process of tapping a new source in to an existing pressurized line without interruption of the system. Our services include water main installation, wet taps, line stops, concrete core boring service, installation of sanitary sewer boots, water main flow & pressure testing, valve & hydrant replacements, bypasses/isolations, hydrostatic water main testing and underground boring services.
