ALWAYS use two stoppers in series with a vent pipe between them.


See illustration in the catalog.

 

How to use The Goodman Stopper

FOUR EASY STEPS
When you first use the Stopper, practice with an empty pipe that has been swabbed clean.

In order to remove the Stopper from the main, release wing nut on screw-rod and thumb screw on locking sleeve, raise on long handle and make fast; pull the Z handle toward you first, then push the long handle from you, thereby releasing the stopper, which when turned face down, is readily withdrawn by pulling on the Z handle only.

After using, the Stopper should be wiped clean. Before storing, coat the metal parts with oil or tallow. Store in a dry, cool place. Wrap in an air-tight cover.

Kept in Stock in Standard Sizes, 3" to 48" • Special Sizes to order on short notice

Stoppers are made to fit Standard inside diameter of pipe. If you want a Stopper for a special size pipe, we can make it if you give us the inside measurement of the pipe.
