Abstract
In a bath waste and overflow arrangement, a system and method for easily and accurately adjusting a valve actuating linkage to the proper length. An adjustable overflow tube assembly is provided with a graduated scale that indicates the length to which the tube assembly is adjusted. The linkage has a similar scale and is adjusted in its length until such scale provides an indication corresponding to that on the first scale. This correspondence between the indicators on the scales assures that when the linkage is inserted into the overflow tube, its length is proper to accurately locate a valve plug controlled by the linkage.
