If I've mentioned this one before, I apologize. I have a unique plumbing issue and I'm not sure how to proceed.
The sink in the half bath downstairs is clogged. Or is it? A few weeks back, I noticed the water wasn't going down and I assumed it had something to do with the aforementioned fussing of the hair. However, I've since taken the elbow out and am able to see everything is completely clear. I ran a snake about 25 feet and it was also clear. The minute I put everything back together and run the water, the basin fills up. I let it sit for a couple of hours and the basin was still completely full. I took everything apart and snaked once again, but the exact same thing happened.
So here's what I think is going on: the vent pipe is clogged and the forces that should allow the drain water to flow through aren't strong enough to let the water get past the elbow. I believe the upstairs sink is connected to the same vent but because it's on the second floor, it seems to be working properly. I do notice that the drain upstairs smells, however.
Any thoughts? I'm not even sure who to call for this kind of thing.
