Water closet fitting installation assembly

Abstract

A water closet fitting installation assembly for installation and optional testing of a water closet fitting within a poured, permanently set floor. The assembly permits the fitting to be rapidly and efficiently installed flush with the floor surface, without risk of fouling the drainage system or blocking drainage of water from the system with slopped or mispoured floor material such as concrete; facilitates mounting and placement of a water closet stool. Optionally the system further facilitates pressure testing of the drain system after the fitting has been installed, without the necessity of placing permanent structures or other blockages in the drain system. The assembly comprises a water closet fitting; a flange adapted for rotatable engagement of an outer circumference of the fitting, whereby a water closet stool may be attached to the fitting in a desired rotational orientation relative to the fitting by means of mechanical fasteners passing through holes in the flange; a collar adapted to prevent contact between the flange, the fitting, and mechanical fasteners used to mount the stool and the material in which the fitting is installed; and a temporary or removable cover plate adapted to cover the fitting and to prevent unset flooring material from entering the water closet fitting or the drain system on installation, so that the fitting and said the system are kept free from the material, and from potential blockage thereby. Preferred embodiments of the fitting assembly further comprise a test baffle adapted to permit the water closet drain system to be tested for fluid tight integrity after the water closet fitting has been installed, without fouling the drain system with the test baffle or pieces thereof after the test has been completed.
