Cylindrical Stopper


CYLINDRICAL STOPPER
FOR SEWER WORK

FOR USE IN SEWER WORK
In sewer work the most practical way to use the Stopper is to drop it into a manhole and allow it to drift with the stream to the desired point where it should be held by the rope and inflated until the flow is stopped.

FOR TIDE WORK
For tide work in either sewers or suction pipe, when the tide is rising drop the Stopper into the end of the sewer pipe. It will float to where you want it. Make the rope fast to a dock pile or other fastening on the bank and inflate the bag.

CARRIED IN STOCK-SIZES, 3" TO 48"
SPECIAL SIZES TO ORDER

This Stopper has been used successfully for testing soil pipes in new buildings. Waterworks engineers use it to save pumping while altering or repairing mains where leaky valves are encountered. It is now used satisfactorily in sewer work, and in at least one instance it saved a city water works a large expenditure of money.
