Abstract
Abstract Apparatus for installing or replacing pipe which extends between a toilet and a ferrule structure projecting from a soil stack couples a discharge pipe to the ferrule structure with a compressible sleeve which extends over facing ends of the discharge pipe and ferrule. Ring clamps compress and seal the sleeve to the discharge pipe and ferrule structure. Ears project from a flange attached to one end of the discharge pipe at a floor which supports the toilet for supporting the discharge pipe from the floor.

Claim 1
Independent Claim
206 words
A plumbing assembly for connecting a soil stack to a toilet supported on a floor, comprising: a ferrule structure extending outwardly from the soil stack, the free end of said ferrule structure having a bead extending generally circumferentally about said free end of said ferrule structure; a discharge pipe having one end adjacent said free end of said ferrule structure, the other end of said discharge pipe extending through the floor and having first connecting means for connecting said discharge pipe to the toilet; a compressible sleeve extending over said free end of said ferrule structure and said one end of said discharge pipe so as to form a flexible coupling between said discharge pipe and said ferrule structure; first clamp means extending circumferentially about said sleeve for compressing said sleeve about said discharge pipe and for sealing said sleeve to said discharge pipe; second clamp means extending circumferentially about said sleeve for compressing said sleeve about said ferrule structure and for sealing said sleeve to said ferrule structure; and second connecting means formed integrally with said discharge pipe and projecting outwardly therefrom into the floor for directly securing said discharge pipe to the floor so that said discharge pipe is supported primarily by the floor.
