Many homes and businesses have old cast iron sewer pipes and are experiencing mainline stoppages and back ups much too often. Over the years, these old pipes naturally accumulate scale and rust on the inside diameter making it rough for paper to flow and often leads to a mainline backup/stoppage. We use state-of-the-art drain cleaning equipment, designed specifically for descaling old cast iron sewer lines. Using a combination of custom designed carbide tipped chains and sandpaper, we are able to remove the old built up scale/rust and smooth out the interior surface of the pipe.
Check out this great video from Picote demonstrating the chain flail being used.
