Ozarks traffic says it's an injury accident, but there isn't a traffic camera in that spot, so I'm not sure how bad it is.

Yeah unfortunately the "bullshit" guys show themselves pretty quickly. Basically if your lateral is blocked then they can try and do a proper cleaning on it, but if it's an older clay pipe that's collapsed then you're going to want to look into replacing it with pvc, which isn't cheap. Mike is the owner for United and quality work is the backbone to his business. I've genuinely never had any issues with any of the guys and they are all extremely kind and easy to work with. They'll tell you what's up and get you going on fixing the issue.

United plumbing is the way to go, I work with them all the time for my job and they're all great. Honestly sounds like your lateral is blocked or possibly collapsed.
