I'm as stuck as my tub on this issue. I tried Liquid Plumr early on and that kind of worked and got some water to go down very, very slowly after some hours at one point but that didn't seem to fix anything as the next time I filled the tub with water, it wasn't draining. Which, this is my problem; the tub is just clogged and not draining any water.
After trying liquid Plumbr, I tried vinegar and baking soda along with hot water and that didn't work. Next I ordered a hand cranked drill auger and an electric drill auger and I wasn't able to have any success with either. When I use the drill augers, where I'm inserting them into the standing waste pipe, they go straight down, and then that's it, it's like I hit a wall. I can't seem to get them to do down where I assume is the low seal trap. I've tried poking down a metal coat hanger that I straightened to feel my way around down the bottom of the standing waste pipe to get a better sense of the situation but again, it's like I'm hitting a wall and I'm at a loss as to what I should do next.
