How It Works
Temporarily plugging a pressurized pipe with the Hydra-Stopper Line Stop Machine, combined with the HSF 250 Line Stop Fitting, starts with a single circular hole — commonly known as a “tap” — cut into the top of the pipe without the need to ream or sever the pipe. After the work is completed, simply remove the line stop machine and attach a completion plug.
Hydra-Stop’s low-cost, lightweight Hydra-Stopper isolates a section of pressurized pipe for repair, maintenance or replacement of valves and hydrants in minutes, eliminating system shutdowns and saving time and money on repairs and maintenance.

FAQ
What are the different methods of line stopping?
Single Line Stop: Stops flow from one direction, such as when installing a hydrant valve. Double Line Stop: Stops water pressure from two sides, such as in a looped wall circuit, e.g. damaged pipe section replaced or main valve installed. Bypass option is available. Double Line Stop with Bypass Option: Whether it is 5 feet or 5 miles, you can permanently replace a line or cut in a valve on a transmission line or service line without customer inconvenience.
What applications call for line stopping?
The following are some of the uses for line stopping in your overall maintenance program: replacing or repairing fire hydrants; tying in new lines or services; rerouting pipes; repairing or replacing valves; performing pipeline maintenance and repairs; changing large meters or backflow preventers; and isolating pipe sections for other types of trenchless technologies.
