Is your drain pipe too short to cut and add a cleanout? I've created a shortcut to which you can trim a hole small enough for your drain snake to fit into, add some ABS glue and stick it right on top. Also glue in a cleanout for easy access. Only works with a 2 inch ABS pipe and 1 and a half cleanout It has been tested and installed and has not failed yet. It definitely won't pass inspection but it's something you can use for home renovation. Make sure the ABS glue dries up pretty good before running water. Only use PETG or ABS filament
