Sump for a swimming pool

Abstract

A sump body for a swimming pool is manufactured by injection molding. The sump body consists of at least three inwardly tapered section created for stackability and as a reinforcement. An upper thickened wall section has a top recess therein for receiving a grating therein. At the bottom of this thick walled section is a radially extending disc surrounding said sump body. There are at least two upper and lower ridges on said disc to act as a water barrier when installed in concrete. There is a lateral pipe connection flange directed inwardly to create a smooth outer contour of the sump body and to enhance the stackability of the sump body. At the bottom of the sump body there is located a drainage flange which is also directed inwardly into the sump body.
