Self-sealing closet flange

Abstract

A closet flange system with attached bolts on the anterior surface and a beveled edge on the posterior surface, a groove on the anterior surface fhr an O-ring to form a seal between the bottom of the toilet and the anterior edge of the closet flange. The anterior surface is connected to a midsection of the closet flange, which includes a keeper ring, securing the position of the closet flange within a drain pipe by preventing removal. An additional O-ring may be positioned on the midsection to block fluid and gas from the drain from rising to contact the keeper ring or escaping outside of the drain pipe. The beveled edge guides the end of the flange into the drain pipe. The system includes bolts which attach the closet flange to the bottom of the toilet before the system is attached to the drain pipe at the floor surface.

         1 . A closet flange system for connecting a toilet to a drain, said closet flange system comprising:
 a rim with at least one opening, wherein said rim consists of an upper surface and a lower surface;   a tube with a first end and a second end; and   at least one bolt.
