Using our rubber or aluminum stopping head technology, the Hydra-Stopper can be used as a single line stop, a double line stop or a double line stop with bypass option. The Hydra-Stopper temporarily plugs a pressurized pipe without disrupting pressure or service upstream of the stop.

How It Works

  • Mount an HSF 250 line stop fitting.
  • Make a line tap into the water main.
  • Insert the Hydra-Stopper stopping head into the main under pressure through the HSF 250 line stop fitting.
  • Perform the repair or maintenance.
  • Retract the stopping head to restore system pressure operation.
