Flow Control Solutions recently completed a 36-inch line stopping project on a live water main, helping maintain uninterrupted service during critical pipeline maintenance. By isolating the pipeline without shutting down the entire system, our team minimized disruption for the surrounding community while completing the work safely and efficiently. This project demonstrates our expertise in delivering rapid, reliable solutions for complex, high-pressure pipeline challenges.

What Is a Line Stop?

Line stopping is a specialized pipeline isolation technique that temporarily seals off a section of a pressurized pipeline, allowing maintenance, repairs, replacements, or system upgrades to be completed while the rest of the network remains in service. It is an ideal solution for projects where avoiding a full system shutdown is critical to maintaining uninterrupted operations.

When Is a Line Stop Needed?

Line stopping is commonly used for a variety of pipeline maintenance and emergency applications, including:

  • Emergency pipeline isolation to quickly control leaks and minimize service interruptions
  • Valve installation, replacement, or repair without shutting down the distribution system
  • Pipeline upgrades, tie-ins, and infrastructure modifications on live water mains
  • Temporary bypass installations to maintain flow during maintenance or construction activities

Flow Control Solutions performs line stopping services on a wide range of municipal and industrial pipeline materials, including:

  • Carbon Steel
  • Concrete Cylinder Pipe (CCP/PCCP)
  • C900 PVC
  • Ductile Iron (DI)
  • HDPE and other commonly used pipeline materials

Our specialized equipment and experienced technicians allow us to safely isolate pressurized pipelines while keeping critical infrastructure operating with minimal disruption.

Whether you’re responding to an emergency pipeline failure or planning a scheduled infrastructure upgrade, line stopping provides a safe and effective way to isolate the pipeline while keeping water service uninterrupted. It’s an efficient solution for municipalities, utilities, and industrial facilities that need to minimize downtime and maintain system reliability.
