Abstract: An example drain apparatus includes a drain body having a cylindrical shape, the drain body configured to position through an opening formed in a floor. The drain body has an upper portion configured for installation above the floor, the upper portion is configured for connection to a drain apparatus pipe of a plumbing system above the floor. The drain body has a lower portion configured for installation below the floor. A pipe hub is formed within the lower portion of the drain body, the pipe hub configured for connection to a pipe of the plumbing system below the floor. An annular space is formed within the drain body between the pipe hub and an outer sleeve of the drain body. A lower drain system pipe is connected to the pipe hub in the annular space.

Abstract: An example drain apparatus includes a drain body for connection to a plumbing system. The example drain apparatus also includes a top drain assembly having a compressible fitting, the top drain assembly configured for removable installation within the drain body. An example drain system includes an apparatus having a drain body and a top drain assembly for installation with the drain body. The example drain system includes a jig configured to cut the drain body below an upper surface of a floor the drain body is installed in so that the top drain assembly is fitted to the drain body substantially level with the upper surface of the floor.
