ABSTRACT:
An improved method for extending a soil pipe flange to floor level by attaching thereto an improved extension device. An extension collar is positioned over a soil pipe flange on which a bead of mastic has been applied. The extension collar, which is made from a flexible material and has multiple attachment slots, is secured to the soil pipe flange by upward extending bolts, and bolt hardware. A wax ring is positioned above the extension collar at floor level. This extended flange facilitates attachment of a toilet fixture to the soil pipe. The method includes techniques for adding multiple extension collars and thus, if required, further extending the soil pipe flange.
