Abstract: A fitting for plumbing systems, such as drain/waste/ventilation (DWV) systems that is chemically and mechanically joinable is described. A socket of the fitting has an interior surface configured for chemically joining with tubing. An exterior surface of the socket includes a plurality of projections extending radially outward therefrom. A collar that includes a sidewall with a plurality of bayonet-style channels configured to engage respective projections is provided. Interaction of the projections with the channels during rotation of the collar with respect to the fitting draws the collar toward the fitting and compresses an O-ring between the collar, socket, and tubing inserted therein to form a fluid-tight seal and/or mechanically couple the tubing in the socket. The collar may include longitudinally depending flanges that are depressed against the tubing by a compression ring to mechanically couple the tubing in the socket.

Abstract: A fill valve assembly for a toilet tank is described. The fill valve assembly includes a two part design. The fill valve assembly includes a fill valve that connects or engages with a shank. A connection between the fill valve and the shank is located in an interior of the tank, which is easily accessed. The fill valve may be easily replaced by disconnecting the fill valve from the shank.

Abstract: Plumbing fitting assemblies are described. The plumbing fitting assemblies use a male and female fitting combination that enables a user or installer to make a sealed connection on an internal diameter of a female part or receiving end by way of an o-ringed shank on a male part or insert end. A connecting device is rotatably attached to the male end. The connecting device also engages to an outer surface of the female part such that the sealed fitting assemblies will not disconnect under normal pressure of a fluid or air working through the assemblies.

Abstract: A breakaway closure member for removably covering an opening in a plumbing device, such as a laundry box, pressure test cap, floor drain, shower drain, closet flange, or the like includes a circular disc with a peripheral rim and a hollow nipple extending outwardly from the circular disc. The peripheral rim is connected to the plumbing device by a thin web or area of reduced thickness. The nipple is radially outwardly offset from the center of the disc so as to be generally adjacent or tangent to the peripheral rim. If the nipple is radially compressed, such as by squeezing with a pair of pliers, the peripheral rim is pulled radially inward in an area proximate the nipple, thereby creating a crack in the area of reduced thickness.

Abstract: A modular utility box system includes separate supply and drain boxes. The supply box has at least one supply opening and the drain box has a drain opening but no supply openings. The supply and drain boxes are interconnectable by a generally U-shaped clip having legs spaced apart a distance selected to accept the narrow dimension of a wall stud therebetween so that the supply and drain boxes may be mounted on opposite sides of a stud. The clip also spaces the supply and drain boxes in the proper vertical and horizontal alignment to facilitate securement of a cover plate to the boxes once installed. The clips engage the boxes to permit interconnected of the boxes in multiple orientations. Elongate brackets may be used to support the erboxes between adjacent studs.
