https://imgur.com/a/LNTG78k I had a plumber came over and unclogged my main line with a snake, after a week it clogged again, he unclogged it again but recommended making a hole in the ground to fix the issue. He mentioned he felt the clog very close to the clean-out, but could not break it completely with the snake. I put a camera in the clean-out to check what the clog would look like. I posted it in the imgur link above. It looks to me like a grease clog. Do I really need to make a hole to fix this, could a degreaser product fix this or some other kind of snake? Thanks!
