my sink has twin basins.

water was going down slowly. in the past when this happens, the pipes are clogged with gunk.

i removed the pipes from underneath the sinks and washed them in the bathroom sink.

all the previous times the water then flowed fine.

this time the water now backs up into the other sink. as if the pipes were really clogged. WTF?! How did i make it worse?

THe pipes seems to have been put back the right way.

What could be the problem?

my bathroom sinks had this happened before. one clogs and water comes up the other. i had to climb to the roof to snake the vent pipe to clear the clog both times. the clog was located past the joint where pipes from both sinks meet. i imagine its similar to your situation.

take a stick and scrape the sludge out of the pipe right below the drain. put it in a sack, dont rinse it down your pipes. thats what i had to do and now my sink is fine

if the problem is in the basin right below the drain, when why is it backing up to the other drain?

It's obvious that it's clogged further down the pipe.

then why was the water only slowly going down the drain before i tried to fix it?

now it's like it's 99% clogged AFTER i cleaned the pipes??

for $1.99 at home depot, this work fantastic if your clog is at the trap under the sink. otherwise you'll need a real snaaaaaaaaaaakee

Undo the P-trap under the sink (use a dry rag/water pump pliers [channel- lock pliers]/pipe wrench to turn plastic nut/s) and clean out the craps that is in there.

Your welcome.

I had the same problem. I tried everything and eventually called a plumber. My drain line had a tree root growing in it.

yes i did clean it out. thats the reason in the past why water was going down slowly.

after i cleaned out the gunk in the pipes, now it's even worse with water actually backing up into the other sink.

WTF is going on?

Do you have a garbage disposal machine? If so, it may be THAT that's clogged.

If the side that does not have the disposal is draining fine, then you have a problem still with the disposal side being clogged.

If both sides of the sink are draining slow, that means the pipe heading to the sewer is now clogged. You have two solutions usually. Either try to use a toilet plunger to free up the clog, or get a snake.

The clog is obviously further down the pipe. As others are saying get a plumper or buy a snake and do it yourself. I'd never used a snake till about a month back when my bathroom sink clogged and I had to unclog it. Be warned doing it yourself might be cheap but be prepared to spend a while using the snake if you haven't used one before. It took me about 2 hours to get the clog out mainly because I simply wasn't applying enough torque to the damn thing (and I though it was damn tight in there!).

but how did cleaning out the pipes make my situation worse?
from slow drain to near blocked AFTER i cleaned out the gunk?

You use something acidic. I am serious. Plumbers do not use the liquid lumber crap. They use acid.

You are Fire! for doing a poor job at cleaning it out.

To redeam yourself, you should take the P-trap off and stick & turns a length of coat hanger with a twisted end down the trap arm to pull out stuffs that is stuck in there. It is likely that food solid & grease built up that clogged it (there is a reason kitchen sink have strainers, and don't pour grease/oil down the sink). Pour several gallons of boiling hot water down the sink and let it drain after you clean out the trap arm, then chase it down with hot tap water for a few minutes to wash the grease away.

It indicates that you have a plug or failed piping at the base of the branch of the building drain if the above doesn't work or the vent is plug. Check the vent on the roof to make sure that it is not plug, or the vent in cabinet if it is an island kitchen sink, then undo the p-trap and run a snake that you can buy from the local hardware stores such as Home Depot.
