THE GARDNER-GOODMAN STOPPER

A stopper for low and intermediate pressures, that can be used on cast iron, steel, oversize or undersize mains. Please specify type and I.D. when ordering. The Gardener-Goodman Stopper is easily inserted in top, bottom or side of main, in open excavation or under pavement. Always use two or more stoppers in parallel with a vent pipe between. This stopper is available in sizes from 2" to 48". The inner bags may be made of Natural Gum Rubber or, in special applications, Nitrile Rubber. Covers are made of Polyester Fabric and may be made flame resistant on request.

  1. To insert the Gardner- Goodman Stopper, screw the container hand tight into the main. The bag should be entirely within the tube while this is being done.
  2. Push plunger piston down to stop collar.
  3. Inflate bag slowly with ordinary tire pump. (Slow inflation gives bag time to shape up.)
  4. WATCH THE GAUGE.
  5. To remove Stopper from main: Remove vent plug and allow bag to deflate. Slowly pull bag up into container. Unscrew.

CAUTION.-Before using on actual work, set up a test pipe, insert the Stopper and observe under pressure. DO NOT OVERINFLATE BAG. DO NOT LEAVE BAG EXPOSED IN SUN. DO NOT KEEP BAG IN CONTAINER TUBE WHEN NOT BEING USED.
