ABSTRACT:
A method and apparatus for installing or replacing pipe which extends between a toilet and a ferrule structure projecting from a soil stack (or other points in a sewage system) does not require replacing the caulked oakum and lead (Pb) joint which seals the ferrule structure to the soil stack. The method 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. A nipple may be inserted into the discharge pipe for attaching another pipe intermediate ends of the discharge pipe. A shield extends about the nipple and conforms to the outside of the discharge pipe to aid in adhesively sealing the nipple to the discharge pipe.
