May end up having to cut the pipe and snake the only part I can't get to. Washing machine didn't go to well, still got a blockage in there. It's draining slowly, I watched it last night going into the septic tank, it's just obstructed by something. Spreading out showers, not running the dishwasher, or washer for a few days. It'll slowly drain like that until I can work on the pipe. We actually have some scrap pieces that size around the shop, I'd just have to buy the pieces to sleeve it back together. Worse case, if 8 can't get it unclogged while I have it cut, I have a friend who works for a plumber who can help. Just gonna be careful with it until I can get to work on it Monday. I'll probably go under the floor and take the cap off tomorrow after work, and see how much it drained. Hopefully it'll be empty, which means it all slowly drained overnight.
