Unclog a toilet (without the overflow)

If the water is rising, don't flush again. Push the flapper in the tank closed to stop more water coming in, then grab a flange plunger. With the right plunger and a slow first push, most toilet clogs clear without water ending up on the floor. A flange plunger, the kind with the soft sleeve at the bottom, seals in a toilet far better than the flat cup plunger most people grab first.

Quick answerDon't flush again. Close the flapper, then use a flange plunger with a slow first push. If that fails, a toilet auger is the next step. No plunger? See other options
Worth checking firstIf the water is rising, don't flush again to test it. Lift the tank lid and push the flapper closed with your hand to stop more water coming in. Then use a flange plunger, not a flat cup plunger; the flat kind can't seal in a toilet bowl.

How to plunge a toilet: a flange plunger sealed in the bowl drain with the clog in the trap
How to unclog a toilet with a plunger. The flange (1) seals into the drain so you can push and pull on the clog sitting in the toilet's built-in trap (2).

Where toilet clogs happen

Most toilet clogs are too much paper, or something that shouldn't have been flushed, like wipes, including the ones labeled flushable. The clog is usually in the curved channel built into the toilet itself, just past the bowl. That's close enough for a plunger to push and pull against it.

The kind of plunger matters. A flat cup plunger is made for sinks and won't seal in a toilet. A flange plunger has a soft sleeve that folds out and fits into the drain, and it works much better.

What causes it

Too much paper

Especially in low-flow toilets.

Wipes and other things that shouldn't be flushed

Even flushable wipes don't break down like toilet paper.

Toys and small objects

A common one in homes with little kids.

A clog further down

If the toilet keeps clogging, something may be stuck deeper in the drain.

  4. Pump firmly 10 to 15 timesKeep the seal and pump in and out with force, pulling back as hard as you push. The pull often does more than the push. Then check whether the water drains.
    Something went wrong?
    • The water drains but it's still slow Keep plunging; the clog is moving. Once the bowl drains to its normal level, test with one flush, with your hand ready to push the flapper closed.
    • It won't budge after several rounds Stop before it overflows and switch to a toilet auger. If an auger doesn't clear it either, the clog is past the toilet.

  5. Use an auger if it won't clearFeed the auger into the drain, crank the handle to push through the clog, and pull it back. It's designed not to scratch the bowl.
    Something went wrong?
    • The auger won't go around the bend Keep cranking while you push gently. Don't force it; twisting is what gets it around the trap.
    • Other drains are gurgling or backing up That points to the main line, not the toilet. Stop using water and call a plumber.

How you'll know it's fixed
  • The water drains out of the bowl
  • A flush clears normally without the bowl rising

Plunging not working? Try a toilet auger.

If the plunger isn't enough

If several rounds of plunging don't work, use a toilet auger. It reaches through the channel inside the toilet without scratching the bowl.

No plunger? A squirt of dish soap and a bucket of hot tap water poured in from waist height can sometimes clear a soft clog. Give it 10 minutes before you try flushing.

If it clogs often and nothing is stuck, check the water level in the tank. It should be about an inch below the top of the . If it's lower, every flush is weaker than it should be.

Keep a plunger handyKeep a flange plunger next to every toilet. When you need one, you don't want to be carrying it through the house.
Renting?If you rent, plunging is yours to do. If a clog keeps coming back or water backs up into the tub, tell your landlord; that points to a drain problem that's theirs to fix.

Clogged toilet questions

Are flushable wipes really flushable?

They get through the toilet, but they don't break down like paper, and they cause a lot of clogs. Throw them in the trash.

What if I don't have a plunger?

Dish soap and a bucket of hot (not boiling) water poured from waist height can clear a soft clog. Wait 10 minutes before flushing.

Why does my toilet keep clogging?

Often it's too much paper at once, wipes, or a low-flow toilet with a weak flush. If it keeps happening, something may be stuck further down.

Something fell in. Should I plunge it?

No. Plunging can push a solid object deeper, where it's much harder to get out. Reach in with a gloved hand if you can see it, or use a toilet auger to hook it.

Can I use a sink plunger on a toilet?

It usually won't seal in the toilet's curved opening. A flange plunger works far better and costs about $10.

What if there's waste in the bowl?

You can still plunge. Pull the bath mat out of the way, wear rubber gloves, go slowly so it doesn't splash, and keep paper towels and a disinfecting cleaner nearby. Rinse the plunger in the bowl with a few clean flushes afterward.

Should I flush again to see if it cleared?

Not while the bowl is still full. Wait until the water drops to its normal level on its own, then flush once. If it clears, flush a couple more times to move everything along.
