Hydra Stop - Lightweight Hydra-Stopper Line Stop Machine
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. Our Hydra-Stopper is effective on any commonly used pipe — steel, cast iron, ductile iron, asbestos cement, concrete and PVC.
The Hydra-Stop water line stop system utilizes a line-stopping technique that temporarily plugs a pressurized pipe without disrupting pressure or service upstream of the stop. A pressure tap is first made into the main, allowing insertion of the Hydra-Stopper plugging device into the main under pressure.
Water line stopping may be used as part of your overall maintenance program to:
- Replace or repair hydrants
- Tie in new lines or services
- Perform pipeline maintenance and repairs
- Change large meters or backflow preventers
- Abandon wells or storage
There are several types of line stopping methods. A single-line stop prevents flow from one direction, which is useful for installing a hydrant valve, for example. A double-line stop bars the flow from two sides, such as in a looped system. A double-line stop with bypass option — whether 5 feet or 5 miles — lets you permanently relocate a line or cut in a valve on a transmission line or service line, without customer disruption.
