Quick Answer
To use a drain snake on a toilet, use a closet (toilet) auger, not a regular drum snake. Pull the cable up into the tube, set the rubber-sleeved bend in the bottom of the bowl’s drain opening, then crank clockwise while pushing the cable in until you hit and break up the clog. Retract slowly, then flush to test. Most clogs clear in 10-15 minutes.
Key Takeaways
- A 3- or 6-foot closet auger is designed for toilets and has a protective sleeve that prevents scratching the porcelain.
- Try a flange plunger first; use the auger when plunging fails or a solid object is stuck.
- Turn the handle clockwise in both directions of travel and never force the cable.
- If several drains back up at once, the problem is likely in the main sewer line and needs a plumber.
A toilet auger reaches through the toilet’s built-in trap, the S-shaped channel inside the base where most clogs lodge. Used correctly, it clears paper wads, wipes and small objects without chemicals and without removing the toilet. Here is how to do it cleanly and without damaging the bowl.
Toilet Auger vs. Regular Drain Snake: Which Should You Use?
| Feature | Closet (toilet) auger | Drum or hand drain snake |
|---|---|---|
| Typical cable length | 3-6 feet | 15-50 feet |
| Bowl protection | Rubber or vinyl sleeve on the bent tube | None; bare cable can scratch porcelain |
| Designed for | Toilet trap clogs | Sinks, tubs and branch drains |
| Ease of use in a toilet | Easy; the bend guides the cable into the trap | Awkward; the cable tends to coil in the bowl |
If you only have a sink snake, you can use it carefully, but a closet auger is inexpensive and far less likely to leave gray scratch marks on the porcelain. For tub clogs, see our guide on how to unclog a bathtub drain.
What You Need Before You Start
- Closet auger (3-foot for most toilets, 6-foot for stubborn clogs)
- Rubber gloves, ideally elbow-length
- Old towels or rags around the base
- Bucket and a cup or small container for bailing
- Flange plunger (the type with an extended rubber cup)
- Disinfectant spray or wipes for cleanup
How To Use a Drain Snake on a Toilet, Step by Step
Step 1: Stop the Water and Protect the Area
If the bowl is close to overflowing, remove the tank lid and push the flapper closed, then turn the shutoff valve behind the toilet clockwise. Lay towels around the base and put on gloves. If the bowl is very full, bail some water into the bucket so it will not splash.
Step 2: Retract the Cable and Position the Auger
Pull the handle up so the cable tip is drawn into the bent end of the tube. Place the curved, sleeved end into the drain opening at the bottom of the bowl, with the bend facing the direction of the trap, which usually curves toward the back of the toilet.
Step 3: Crank and Feed the Cable
Hold the tube steady with one hand and turn the handle clockwise with the other while slowly pushing down. The cable will snake up and around the trap. Keep cranking gently when you feel resistance; you are either working around a bend or hitting the clog.
Step 4: Break Up or Hook the Clog
When the cable stops advancing, crank back and forth a few turns to break up soft material or to snag wipes and paper. If the handle reaches the tube, the cable is fully extended; do not force it further.
Step 5: Retract the Cable Slowly
Keep turning clockwise while you pull the handle back up. This keeps the cable from kinking and helps pull out anything it has hooked. Remove the auger and drop any debris into a trash bag, not back into the bowl.
Step 6: Test, Repeat and Clean Up
Turn the water back on and flush once while watching the level, ready to close the flapper. If the water drains slowly, repeat the process once or twice. Rinse the auger in the bowl with a few flushes, spray it with disinfectant, and let it dry before storing.
Tip: Do not pour chemical drain cleaners into a toilet before or after snaking. They rarely clear toilet clogs, can splash on your skin when you work, and can damage older pipes.
Why Won’t the Toilet Unclog After Snaking?
- The clog is past the trap: a 3-foot auger only reaches the toilet’s own trap. A blockage further down needs a longer snake through the toilet flange or a cleanout.
- A hard object is stuck: toys, phones or toothbrushes may need the toilet pulled up and the object pushed out from the bottom.
- Main line blockage: gurgling sinks, a backing-up tub or sewage smell in several places point to the main sewer line.
- Vent problems: repeated slow flushing with no visible clog can mean a blocked plumbing vent on the roof.
- Low-flow toilet issues: partially closed shutoff valves or a low tank water level weaken every flush.
When Should You Call a Plumber?
Call a licensed plumber if two or three attempts with an auger fail, if water comes up in a tub or shower when you flush, if you suspect a tree root or collapsed pipe, or if the toilet rocks or leaks at the base after the clog clears. Persistent damp spots or a rising water bill can also mean a hidden leak; our guide to finding underground water leaks explains the warning signs.
Safety: Toilet water carries bacteria. Wear gloves, keep your hands away from your face while working, and wash your hands well afterward. Disinfect the floor, bowl rim and tools when you finish.
How Do You Prevent Toilet Clogs?
- Flush only human waste and toilet paper. So-called flushable wipes, paper towels, cotton swabs, dental floss and sanitary products should go in the trash.
- Use less paper per flush, or flush twice for large loads with a low-flow toilet.
- Keep a lid on toddlers’ curiosity with a toilet lock if small toys keep disappearing.
- Check that the tank fills to the water line marked inside it so each flush has enough volume.
For sanitary products, follow our guide to disposing of sanitary pads properly, and use an EPA-registered disinfectant spray to clean up after any overflow.
Frequently Asked Questions
Can you use a regular drain snake on a toilet?
You can, but it is not ideal. A bare drum snake can scratch the porcelain and tends to coil in the bowl. A closet auger has a protective sleeve and a bent tube that guides the cable into the trap, so it is safer and easier.
Which way do you turn a toilet auger?
Turn the handle clockwise while feeding the cable in and keep turning clockwise as you retract it. Consistent clockwise rotation helps the cable navigate bends and stops it from unwinding or kinking.
How far does a toilet auger go?
Most closet augers have a 3-foot cable, which reaches through the toilet trap where most clogs form. Six-foot versions reach a little further. Clogs beyond that need a longer snake through the floor flange or a cleanout.
Can a toilet auger damage the toilet?
A closet auger used gently rarely causes damage. Scratches come from bare metal touching the porcelain or from forcing the cable. Keep the sleeved end seated in the drain and never crank hard against a solid stop.
What if the toilet is still clogged after using an auger?
Try the auger two or three times. If it still will not drain, the clog may be past the trap, a solid object may be lodged, or the main line may be blocked. If other drains gurgle or back up, call a licensed plumber.
