I'm about to give up as much as I hate to throw in the towel which is by now quite dirty...LOL! I have a sink drain that goes down very slowly. I opened the trap which was clear, and determined that the clog is between the piece of pipe on the other side of the trap and the wall. The pipe bends down and only comes about about 16" or so from the wall.

It's an apt. house and I checked with the building and there's no other clogged drains reported so it's not in the stack that feeds all apts. I tried one of those crank snakes in that pipe with the trap off and it's still clogged. What I was hitting was I guess the far side of that main pipe when I put the snake in. I had thought that was the blockage, but then saw a diagram of how the pipes connect.

What I don't understand is why the snake at least won't poke a hole in whatever is clogging it. All I was able to pull out was a bit of hair. The water went down more, before all this plunging. I did pull a large hair clog out that I thought was the problem, but that was near the drain, and it didn't help

BTW: Plunging vigorously caused it to drain well for just a few seconds but I think that's creating a vacuum just lifing the water up, and when I stop it's the same. Could that be?

It seems the snake should be able to clear it at least somewhat as it's a short pipe. Would really appreciate any ideas, other then to call a plumber ;-).

Thanks!
