Document Type and Number:
WIPO Patent Application WO/2011/072025
Kind Code:
A3
Abstract:
An improved method of installing a closet flange allows installation of plumbing fixtures with a reduced likelihood of leaks. The method involves telescopically fitting an inner or outer surface of a drainpipe to a surface of a cylindrical portion of a hub of a closet flange, where the hub has a base flange extending therefrom; and securing the base flange against the upper surface of a subfloor. A first layer of sealant is applied to an upper surface of the base flange; and a flooring membrane is secured to the upper surface of the base flange by the first layer of sealant. A second layer of sealant is applied to an upper surface of the flooring membrane; and the upper surface of the flooring membrane is clamped between the base flange and a clamping ring. The method may be performed using a two-part closet flange for connection to a drain pipe for a toilet. The two-part closet flange comprises a cylindrical hub adapted to telescopically connect to the drain pipe; an annular flange radially extending from the cylindrical hub; a clamping ring; and a means to clamp a flooring membrane between the clamping ring and the annular flange.
