Cleaning a sewer or drain line is not an easy job, and using a standard 3/8 inch diameter pressure washer hose simply won't do the trick. When cleaning small diameter pipes, try our 1/8 inch diameter sewer and drain cleaning hose. Its smaller size can be pushed through bends in sewer lines, and allows for quick clearing of debris and clogs. Available in 25 ft, 50 ft and 100 ft sections.
