Whether your bathroom sink is draining slowly or not at all, you don't need to spend tons of money on a plumber, you just need to learn how to unclog a bathroom sink. While there may be that one stoppage that is more than a clog, most bathroom drain issues are simply a buildup of gunk and grime in the pipes. This gunk is nothing strange or weird, it is simply stuff that collected in the pipes over years of use. There are a variety of tools and methods to unclog a sink, so when the pipes stop flowing, pull up your sleeves and choose the method that works for you.
- Use a chemical clog remover, the kind you can find in more supermarkets. If you have these in your house, this may be the easiest way to clean out a drain. Simply pour the substance down the drain, wait about 15 minutes, then flush with hot water. It will take about half a bottle to unclog most drains.
- Place a plunger over the drain. Make sure that the sides of the plunger make a solid seal against the base of the sink and stuff a towel or handcloth into the overflow drain. Press up and down on the plunger, pushing water down into the clog trying to break it up. After a few seconds, you should see some improvement in the drain, so continue to plunge until the drain is clear.
- Unscrew the plumbing beneath the sink. For most sinks this will be PVC piping that you can easily unscrew, but you may need a wrench if the nuts are tight. Be sure to put a bucket beneath the pipes before you begin. Run water through the downspout form the sink to see if that is where the clog is, then check the curved piece that you removed. If the clog is in one of these pieces, you can probably get to it with a screwdriver. If you can't find a clog, it means that it is deeper in the pipe and you will need an auger.
- Place the snake part of the drain auger into the pipe that heads into the wall. Continue to feed the snake in until it will not go in anymore. Once it stops pushing in, release another foot of snake and flip the switch to lock the snake. Push in on the auger while you turn the handle. This will force the snake through the clog and break it up. When you feel the resistance stop, pull the auger out of the pipe, but be careful as the clog is likely to come out as well, so have a bucket or come rags ready.
