This is a video of a General Pipe Quick Fix model "QF" Repair Sleeve which holds the cutter blades that was mounted by Home Depot on a Easy Rooter Drain Cleaning Machine with a 100' x 5/8" flexicore inner cable. Unfortunately, the quick fix repair sleeve and attached cutter blades were detached under torque about 21 feet into the cast iron drainline below the customers concrete slab. This is a video on how to try to retrieve the quick fix adapter and remove it from the drain line. You will need a sewer camera, a 3/8" x 75' drain machine and a small auger bulb retrieval tool head with the leading tip coil pulled a 1/2" out lengthwise (uncoiled) from the spiral ring and a 1/4" to the outside edge of the retrieval head (to the side). Tip: Never use one of these adapters in a drainline underneath the slab. If this wasn't retrievable, the slab would have to be jackhamerred and 3 tons of rock and concrete excavated into the bedroom to get access to the pipe for cut out and removal which will cost thousands of dollars. "Tip" Use a properly welded cable head when snaking underneath a concrete slab and preferrably one that contains a inner core cable in case the outer coiled cable snaps. For instance, a General Pipe Cleaners inner core cable such as a flexcore cable.
