Hey guys,
Our bathroom sink has been slow to drain for a couple of weeks and yesterday I decided to take the pipes out underneath the sink to clear the trap from gunk and hair. I took the trap apart and also the pipe that's connected to the wall. Indeed, there was some hair and gunk in there However, I put everything back together and now the sink will not drain at all! I used a plunger and got up what looked was some greenish paint chips and some black stuff but not really enough to consider that to be the problem of a clog. It's like it won't drain past the wall, like there's no pressure? I also checked the vent on my roof, the vent isn't located (as far as I can tell) right underneath the bathroom, but a meter or so to the right. The vent was clear all the way down from what I could tell. I havn't used an auger yet, but considering the sink worked yesterday do I need to buy one?
I don't have a basement or 2nd floor, and I'm using city water if that matters.
Any ideas what I can do here? It's just weird to me that it was working, albeit a bit slow, yesterday and not now after the cleaning.
Thanks.

EDIT: I forgot to mention that I do have a rusted off stopper (is that what they're called?). One of those things that you pull up on the faucet that holds water in the sink. My sink doesn't have the stopper cap, it only has the metal rod behind the sink and the other rod with the ball part attached to the pipe. Both of these are really rusted so I don't think they'd work even if mattered. I don't know exactly how these work but the part that the ball is connected to that goes into the pipe feels like it's almost corroded. I don't know if this matters since I've never used it, but I thought I'd give all the info I can here.

 

I have no good insight to give, but let's rule some things out so all the people smarter than me can help you;

Are any other fixtures slow to drain?
Prior to this illogical repair, has the previous problem been constant, slowly getting worse, or happened one day.
Has the weather been especially wet recently?
During your "repair", did you insert anything into the pipe still in the wall that could have caused a mostly clogged pipe with a bit of a gap to have a bunch of gunk fill in that gap and create a full clog?

 

Thanks for the quick reply Michael.

It seems that the sink just started becoming slow to drain in a couple of weeks or so, not too much of a bother just noticeable. If I hadn't tried to clean it up yesterday I think I could've lived with it being like that. No, I didn't insert anything into the pipe that I don't think...I can't be 100% sure but I mostly just scraped some gunk out with a wire, not really pushing anything around.

It did rain a good deal the other day but the sink didn't get noticeably worse then.

My toilet has been slow to flush for years at times. Tub seems normal.

 

From my own experience, I tore out the drain of my bathroom sink and the 1 1/4 drain had an inner diameter of about 1/2 inch with all the gunk that it had. If you loosened up anything in a pipe like the one I had, it could easily have clogged it all the way.

Sorry that all I can do it point out possible causes, but not any solutions.

 

Hey Michael. You're post gave me the courage and inspiration to try and see if there was a clog. I used a bent wire hanger to get down into the t-section and sure enough after a bit of messing with it I pulled out something that resembled a dead rat. I would've have guess it could've gotten clogged the first time I tried to fix it, but indeed. You were right. It works now. Thanks!
