ABSTRACT:
An improved water closet flange for connection to a plumbing fixture is described. The improved flange comprises an anchoring element or outer flange, connected to a flexible conduit tube or flexible sleeve, in which is attached an O-ring type of gasket. The improved flange connects a toilet bowl outlet to a waste drainpipe outlet without any flow reduction in between both connecting elements. The improved flange allows the connection between a toilet bowl discharge and a well placed vertical waste drainpipe. The improved flange also allows the connection between a toilet bowl discharge and a waste drainpipe outlet that is offset, horizontally oriented, or diagonally placed. The improved flange may further comprise an O-ring type of gasket disposed on the exterior of the flexible sleeve to provide a tight seal between the outer surface of the flexible sleeve and the inner surface of a waste drainpipe. The flexible sleeve can be implemented in a variety of sizes or diameters, including, for example, 3 inch (7.5 cm) and 4 inch (10 cm) diameters. An alternative embodiment of the flexible sleeve can fit either 3 inch or 4 inch drainpipes with the help of an appropriate O-ring seal of the appropriate dimensions.
