Fix a Clogged Drain
Fix a Clogged Drain first, you can try plunging it—yes, with the same tool that you might have thought was only for the toilet. (If you’re working with a bathroom sink, be sure to clog the overflow hole that’s near the top of the basin.)
Plunge it like you normally would a toilet—with a sink plunger of course. The next time you’re around a plunger, take a look at it. Does it have an extended part that goes beyond the dome shape? If so, that’s a toilet plunger—that extra three inches or so is to get deep down into the basin. If it’s just the dome/bowl, then you very well might be using a sink plunger to do a toilet plunger’s job. There is a difference, so take note.
If that doesn’t work, search for a clean-out plug on the main pipe. This handy opening (once unscrewed with a wrench) gives you access to the pipes without disassembly. Use a flexible, but tough brush to get in there and poke around to see if you can clear out any blockages. (Be very careful if you’ve already poured drain cleaners down the drain.)
Be sure to have a bucket on hand below the plug, though, as you don’t want any water splashing down on the floor while you wow everyone with your plumbing skills.
If you’re having some bad luck with the toilet and you find yourself without a plunger or if the plunger fails you, pour about a cup of dish detergent down there. It’ll act as a lubricant for the clog to wash down. You’ll need to let that work its magic for about 10 minutes. But while you’re waiting, grab a good amount of hot tap water—we’re talking multiple quarts here—but not hot enough that it’s boiling. Pour it into the toilet bowl from an elevation (not so high as to splash clogged toilet water everywhere). Pour in the water and just the whole mess will go down the drain.
