I have tried draino, but I think I need to pull out the drain and remove the hair and stuff. It drains really slow. I don't know if I should call the landlord because it is something small. But I don't know how to remove the drain. do I just pull it straight out? there are no screws or anything, but it doesn't seem to want to budge and I don't want to break it since it isn't really mine. here is a picture of the type of drain I am talking about:http://upload.wikimedia.org/wikipedia/commons/3/3b/Bathroom_sink_drain.jpg
there is a very handy little tool that you may be able to remove enough of the hair and then the rest will probably flush down. Menard's or home depot have them. It is about 30 inches long and 1/2 inch wide.has sharp little hooks on each side.just run it down into the drain opening up & down, it will hook on to the hair and you can pull it out.do it until you get no more hair. then run hot water down the drain no need to disconnect the trap unless you have more than just hair in the trap Good luck
If you cannot lift the drain cap straight out easily, the drain insert is held by a lever under the sink that is attached to the button that opens and closes the drain. It might be easier to remove the trap below the sink and flush it out. All metal and plastic drain traps unscrew by turning the ring around the place where different pieces join. After the ring is loose, the pieces separate easily. Put a pail or pan under the trap before removing it to catch the nasty water.
Some you can twist to remove it. If it won't twist, get under the sink and you'll see the rod that connects to it, unscrew the collar to it at the drain pipe and pull the rod out then the stopper will pull up. You might want to unscrew the trap and clean it while you are down there. The trap is the S bend in the drain under there. It all unscrews just be sure to put it back together firmly (hand tighten if plastic) and test it by running water in there before you finish up.
The best thing that I can advise you to do, is to remove the drain pipe under the sink, where the elbow is. Make sure that you have a bucket underneath it. It can get quite messy. Clean out the elbow part of the drain pipe, that is where the clog usually is. Also, take something long to get up where the drain stop is and clean that. Then just put everything together. Good Luck! P.S. This is what I do if I don't want to bug my landlord. C
First, remove the stopper. Either it just lifts out (rare) or it is held in place by a rod. Remove the rod by loosening the nut, located in the back of the drain pipe, just below the sink. Once the nut is loose, grab the stopper with one hand and pull the rod out enough to release the stopper. When you pull the stopper out, some hair might come with it. Look down inside the drain and, if there's more hair, grab a piece of wire, make a little hook on the end and pull out the rest of the clog. Reassemble the stopper, which can be a little tricky the first few times, but will work. Tighten the nut and turn the water on. Check for leaks at the nut, tighten a little if necessary. Sometimes teflon tape is required, but not usually. If it still doesn't drain, call the landlord, you've done enough. Good Luck
