Toilet won't unclog with a plunger? What to try next
Stop flushing. If the water’s already rising toward the rim, take the lid off the tank and push the flapper down by hand to stop more water from coming in, then let it settle before you try anything else. Once it’s under control, work through plunging technique first, then hot water and dish soap, then a toilet auger if you still need it.
Stop it from overflowing first
A toilet that’s slow to drain after one flush isn’t an emergency yet. Don’t flush again to see if it’ll clear itself. That’s how a slow drain turns into water on the bathroom floor. If it’s already rising, lift the tank lid and hold the flapper shut. That cuts off the water refilling the bowl right away. Then close the shutoff valve behind the toilet so it can’t refill.
Plunge it the right way
- Use a flange plunger, the kind with a rubber flap that folds out from the bottom of the cup, not the flat cup style made for sinks. It seals far better against the curve of the bowl.
- Make sure there’s enough water in the bowl to cover the cup completely. Add water from a bucket if you need to.
- Push down slowly the first time. That pushes air out of the cup instead of bouncing it around, and trapped air is the reason a lot of plunging doesn’t work.
- After that first slow push, go firm and steady, straight up and down, for fifteen to twenty strokes before you stop to check.
- Pull the plunger away and see if the water drains. If it’s slow but moving, run another round before moving on.
Hot water and a little dish soap
If plunging hasn’t done it, run hot tap water, not boiling, into a bucket. Boiling water can crack the porcelain, and a cracked bowl is a much bigger problem than a clog. Add a good squirt of dish soap to the bowl first. Then, if there’s room, pour the hot water in from a foot or so above it. The soap helps loosen whatever’s stuck, and the pour gives the water a little push. Let it sit for ten or fifteen minutes before you plunge again.
When you need a toilet auger
A toilet auger, sometimes called a closet auger, is built to get around the tight bend inside the toilet. A rubber sleeve near the tip protects the porcelain while the metal cable does the work. Feed the cable in slowly, following the curve of the bowl rather than forcing it straight down, then crank the handle as you push forward. When you feel it catch on the clog, keep turning while you pull back gently. That breaks up or hooks whatever’s stuck so you can pull it out or push it on through.
What not to do
Skip the chemical drain cleaner. It isn’t made for standing water in a bowl, and it can splash back on you or just sit there doing nothing. If you already poured some in, don’t plunge or auger, and tell the plumber. Skip the coat hanger too. Uncoated wire scratches the glaze inside the bowl, and once that glaze is scratched, waste sticks there from then on.
If a kid’s toy or a phone went down, stop trying to auger it out. Fishing for a hard object can push it further in or wedge it against the trap. Sometimes the toilet has to come off the flange to get it out from underneath, and that’s worth handing off rather than fighting for an hour.
When it’s not really the toilet
If other drains in the house gurgle when the toilet flushes, or the tub backs up around the same time, the clog isn’t in the toilet at all. That points to the main line, and no amount of plunging the toilet will fix it. Here’s how to spot signs of a clog in the main sewer line.
Wipes are behind a lot of repeat clogs, even the ones labeled flushable. They don’t break down in the pipe the way toilet paper does. If your toilet clogs every few weeks, that’s worth a look, and our drain cleaning page covers how we’d go after it.
