Do I have to manually keep pulling this snake spring and feed it into the drain or does it automatically come out? The manual part takes a lot of strength to pull this snake.
Does the cable power feed into the sewer duct or do you have to manually push it in and manually pull it out of the duct ?
What is the purpose of reversing the cable after it is insisde the duct? Does that help removal?
