Photo 2: Test for a clog
Don't flush the toilet if you suspect that it's clogged. Instead, remove the tank lid and lift the
flapper valve slightly to let a cup or two of water into the bowl to see if the water goes down.
Flushing a clogged toilet may flood your floor!

For about 90 percent of clogged toilets, you only need one special tool—a plunger. Buy one with an extension flange on the rubber bell-shaped end (lead photo). It's designed to fit toilets better so you can deliver more “oomph” to the plunge. You could pull a woodchuck from a hole with one of these things. It'll unplug sink and tub drains too, if you simply fold the flange back into the bell.
A poor flush means that your toilet drain is either partially or completely plugged. A toilet that's completely plugged—a no-drainer—is obvious. The toilet bowl will fill to the brim with flush water and perhaps overflow. Give the water level 10 minutes or so to drop, then attack the problem with a plunger (Photo 1).
However, most clogged toilets are slow drainers, that is, flush water partially fills the bowl but doesn't rush out and clean away the waste. The water level remains high, then usually drains down to normal height within a minute or two. You might not know the toilet is clogged until you flush it. So if you suspect a problem, test the drainage first as we show in Photo 2. If it doesn't drain, don't flush it. Reach for the plunger.
Photo 1 shows how a plunger fits over and seals the toilet drain. Wear rubber gloves—things can get messy—and follow these plunging tips:
- Make your first plunge a gentle one. Initially the bell is full of air. A hard thrust will force the air back around the seal and blow water all over the bathroom and you!
- Once you force out the air, plunge vigorously in and out, maintaining the seal. You'll be forcing water both directions in the drain, which will effectively loosen most clogs. Stick with it, plunging 15 to 20 times if necessary.
- Be patient. Try alternating between steady strokes and occasional monster heaves.
- Keep enough water in the bowl so the plunger stays covered. Trying to force air through the toilet trap won't generate much pressure.
