Abstract: A snake cleanable fluid flow system is provided which incorporates a first fitting in the form of a clean-out elbow and a second fitting in the form of a tee. Each of the fittings have a first passageway open at each end and a second passageway intersecting the first passageway. The clean-out elbow is provided with a baffle which selectively directs a snake inserted in its second passageway into a predetermined end of the first passageway. The tee also has a baffle which diverts a snake inserted into either end of its first passageway into its second passageway. The tee and clean-out elbow are connected by a pipe and a partitioned pipe is connected to the second passageway of the clean-out elbow so as to facilitate insertion of a snake. The baffles facilitate cleaning the fluid flow system by deflecting the snake inserted in the clean-out elbow and tee.
