Abstract

A plastic mounting ring comprises two plastic arcuate members each having a flat upper profile, a flat lower profile and a predetermined thickness. Each plastic arcuate member has a lip extending radially inwardly with an inside diameter that allows it to engage the sides of the channel formed by the flange on the water closet coupling on which it is to be mounted. A corresponding first end of each arcuate member has a notch out of the lower level of its thickness. A second corresponding end of each arcuate member has an extension, coplanar with its flat lower profile, which engages the lower surface of the base of the opposite end of the other arcuate member. The members are fitted together to form a mounting ring having a flat upper profile and a flat lower profile. The mounting ring can be used to replace a flange formation of an installed water closet coupling without removing the total water closet coupling. According to the method, a part of a flange formation is cut away from the installed water closet coupling so that no remaining portion of the installed water closet coupling is wider than the installed connecting pipe. A replacement water closet coupling is provided having a replacement connecting pipe with an inside diameter greater than the outside diameter of the installed connecting pipe to an extent which causes the replacement connecting pipe to fit closely around the installed connecting pipe. A replacement water closet is installed by mounting the replacement connecting pipe around the installed connecting pipe.
