All plumbing systems develop clogs—there’s simply no way to avoid it. However, most stopped-up sinks and plugged toilets can be fixed without calling in a plumber. What you need to complete the job on your own are the right tools and a little determination.

We’ll show you how to clear stubborn clogs in a kitchen sink, bathtub, toilet and floor drain. These proven techniques will dislodge virtually any clog. Remember, if you can’t clear a clog after a few attempts, turn the job over to a drain-cleaning service or licensed plumber. Exerting too much force can permanently damage a pipe or fixture.

The specialized plumbing tools used to combat clogs are affordable, and they’re available at any hardware store or home center; you can even rent some.

The first tool to reach for when trouble arises is a plunger ($5 to $10). This plumber’s friend clears clogs from most fixtures, including sinks, tubs and toilets. Every homeowner should keep one handy.

To dislodge clogs located farther down the drainpipe, use a cable auger, or plumber’s snake, a long, flexible steel cable wound around a spool that’s fitted with a hand crank. Cable augers are available in lengths up to 100 ft., though a 25-ft. model ($15 to $25) will suffice for most any household clog.

A closet auger ($15 to $40) is specifically made for snaking out toilets. It, too, is equipped with a hand crank, but instead of a spool, the cable is encased in a rigid shaft. The auger end is bent at a precise angle to fit through the tight curves of a toilet trap.

For a very large clog or one that’s far from the fixture, rent an electric power auger ($15 to $30 per day). This machine—basically a large cable auger powered by an electric motor—is very effective at cutting through virtually any clog, even tangled tree roots. Before bringing home a power auger, be sure the rental agent shows you how to safely dispense and retrieve the cable.
