Abstract: A waste pipe fitting assembly includes a tee wye fitting that has an outlet, a first inlet and a second inlet. The outlet is fluidly connectable to a sewer line of a sewer system. The second inlet is fluidly connectable to a drain pipe to place the drain pipe in fluid communication with the sewer line thereby draining water from the drain pipe into the sewer line. A pair of hangers is each of the hangers is coupled to the tee wye fitting and each of the hangers engages a respective support for suspending the tee wye fitting from the supports. Moreover, each of the hangers engages the respective support at an adjustable height to inhibit fluid from collecting in the tee wye fitting.
