Line stopping is a technique of isolating a water piping system to provide a shut off where none exists. Line stopping bypasses and isolates specific sections of your water piping system for replacing or repairing hydrants, tying in new lines or services and performing pipe repairs.. The technique was introduced to the water industry in the 1980’s.
Line stops utilize a fitting mounted to the host pipe. A line tap is made and the stopping device is mounted and completes the flow stopping procedure. The line stop temporarily stops flow to allow repairs or maintenance without disrupting service. Once work is completed, the fitting is sealed with a completion plug and flange. The fitting is left in place on the host pipe.
