Not to spam, but I DID write up an instructable on this very thing...
Look at the Instructables listed to the right of the page.
Any idea what caused the clog? Hair (especially really long hair) is notorious for getting caught in the P-trap you can sometimes plunge it through, but it might cause a pro lem further on down. So like cattrampoline and ismael suggested, dims telling is best. If you already tried drano or similar chemical, put 1/2 cup baking soda in the sink and flush it with 4 cups of water. Let it drain down, no matter how slowly. You don't want to plunge or dimsmantle it and get the chemical on you. This is one of the better videos on removing the p-trap, http://www.youtube.com/watch?v=adJrVNJpf2M&feature=youtube_gdata_playerWho knows you might find a treasure plugging it up and be glad you didn't flush it away! Good luck
Hi,hair is the main problem with slow or clogged bath drains. Check out a drain tool like The Drain Claw at www.thedrainclaw.com. You can unclog bath drains without having to use dangerous chemicals.
Definitely rinse the caustic Drano out. Then dismantle the pipes as ismael01 suggests and scrape the gunk out. Last time I did this, there was just icky crusty stuff built up on the pipes, but there could be any number of objects wedged in there. Toothpicks, coins, missing jewelry, etc. can find its way into the sink. Wear gloves, have plenty of paper towels on hand, and a bucket under the trap (P-shaped bend in the pipe). And work on an empty stomach or you are likely to have an extra mess to clean up.
If your bathroom sink has the type of stopper where you pull a rod up to make the plunger type stopper retract into the drain, then you can be most assured that the clog is on that mechanism. First, since you have used Draino, you need to put a decent amount of water in the sink and let it drain out, no matter how slow. That will help wash away the caustic Draino. Next, under the sink, you will see a mechanical linkage that connects the rod (as mentioned above) to a lever that actuates the plunger. Usually, there is some sort of spring clip holding those 2 pieces together. Pinch the spring clip and loosen up the assembly enough to allow at least 1" of movement, or better yet, disconnected completely. Now, there is a large nut, most likely plastic, where the lever goes into the drain's tailpiece. Carefully remove this nut and the lever will pull out. At this point, you can remove the stopper from the topside and most of the gunk (usually hair) will come with it. You may need a tool (long flathead screwdriver, J-hook, long crochet needle, long needle nose pliers, snake, anything you can hold that will go into the drain to grab the remaining clog. Once all is removed, re-assemble in the reverse order of disassembly, making sure to get the lever into the hole on the bottom of the plunger. Adjust the lever/rod connection to properly seat the plunger/stopper. Good luck, Qa
Since you already used Drano, be careful not to splash on yourself any of that water to avoid any chemical burns. Try a tool called a "snake" to remove the clog. There is one that works with a power drill and by hand. It is always a good idea to invest in one if you are a homeowner. Most clogs tend to happen wherever there is a pipe union or elbows. I hope you solve your problem.
i reccomend you take the pipes off from the bottom using a monkey wrench. then scrapping the blockage out. also hard pipe tends to break if they are fairly old. i reccomend you be careful and then convert the hard pipe to plastic pvc. last forever. and easier maitenace. your local homedepot will help with this
Nothing beats the mechanical approach; i.e some sort of long skinny tool that can be stuck down the drain and used to pull out the obstruction. For example, I have in the past, pulled junk out of a drain using a piece of steel wire with a hook on the end. There does exist a professional tool, called a "drain snake", and you can see some pictures of those here:http://www.google.com/search?tbm=isch&hl=en&q=drain+snake So you can see basically, how the "snake" is intended to work, but like I said above, a piece of wire can often be made to work in place of the professional tools. Also for more pictures and advice, see the related panel, on the right there. -----------------> It looks like there are several 'ibles on this topic.
