Abstract
A break-away fitting facilitates installation and removal of a pump in wet well system, along at least one guide rail. When installed, the fitting mates an outlet of the pump to an outlet pipe of the wet well. The fitting has a body with a first and a second surface, the surfaces arranged to be substantially perpendicular to each other. A flanged opening in the first surface is sized and adapted for attaching the body to the outlet flange of the pump. The second surface has indentations for engaging the at least one guide rail, so that the body slides in the vertical channel. To minimize the dangers from static electricity in the wet well, the body may be formed from a non-sparking material, such as brass or bronze, or a surface of the indentations may be covered by a non-sparking material, including high-density polyethylene or poly(tetrafluoroethylene).
