STOPPER OVERVIEW

In water works, the practice is to place the stopper in the open end of the pipe after the cut out is made where a leaky valve is encountered. This permits the work to be continued on dry ground and the only wet joints would be on the sleeve at the closing in point. If leaky valves are encountered, a Cylindrical Stopper will hold back all leakage ­ enough to furnish water to the second floor of houses on the line shut down. Leakage may be alternatively wasted through a hydrant on the line.

In sewer work the stopper is dropped down in he a manhole and allowed to drift with the steam to the desired point where it's held by the rope and inflated until the flow is stopped.
