How to remove roots in sewage drain
There at different styles of augger heads on larger units. Most folks are familiar with the cork screw style end that will grab chunks of hair and roots but there are also several styles of cutting heads the one I have the best luck with for clearing roots is a head that has 2 flat loops that are about 3" long and then 2 more flat loops that are a bit shorter but are the same diameter as the longer ones the loops are a flat stainless material that is fairly thin. These won't cut through a plug very well but they scrape the walls and cut the roots. I have found once roots get in the pipe it becomes an annual event until the pipe is replaced (even using chemical inhibitor). The large augger I purchased came with 3 or 4 heads , I found the best thing was to the head that looked like a hunting arrow to punch a hole in the mess then use the one with the loops. My unit has a power feed lever I go forward until I notice some back pressure then let it spin at that location for a little while move forward very slowly so the bands or loops cut the roots loose I do run water when doing this so everything is flushed as it is cut loose. The first time I did this I did not run water and all the chopped up root pieces plugged at the entrance to the main line and I had to run the cork screw head in to pull the roots out. I have had this happen in 2 homes 1 got so bad I replaced the line the other I just ran the snake every spring and never had and more problems until the next spring.
