Quick answer

If your toilet won't plunge, start by checking for a clog in the drain pipe. Use a plunger to create a tight seal and push and pull forcefully. If the clog persists, try a toilet auger or call a professional plumber.

Confirm the symptom

Water is not draining from the toilet bowl after flushing
Plunger does not create suction or movement
Toilet water level rises but does not drain
No water enters the bowl when the handle is pressed
Toilet tank fills but bowl remains full of water

Tools and prep

Rubber plunger
Toilet auger (snake)
Gloves
Bucket
Plumber's snake or closet auger
Turn off water supply to the toilet
Ensure the area is well-ventilated

Step-by-step troubleshooting

Check Water Supply
Do: Locate the water supply valve behind or near the toilet and ensure it is fully open.
Observe: Water should flow into the tank when the valve is open.
Means: The issue may be a closed water supply valve.
Next: If the valve is open, proceed to the next step.
Inspect for Clogs
Do: Visually check the toilet bowl and trapway for any visible clogs or obstructions.
Observe: You may see a blockage such as toilet paper, waste, or foreign objects.
Means: A clog is likely preventing water from draining.
Next: If a clog is found, proceed to the next step to remove it.
Use a Plunger
Do: Use a rubber plunger to create a tight seal over the drain hole and push and pull forcefully several times.
Observe: Water should start to drain from the bowl with each plunge.
Means: The clog may be dislodged with plunging.
Next: If plunging is ineffective, proceed to the next step.
Use a Toilet Auger
Do: Insert the auger into the drain hole and push it through the trapway until resistance is felt. Rotate the auger to break up or remove the clog.
Observe: You may feel or see the clog being cleared as you rotate the auger.
Means: The clog is likely deeper in the drain pipe.
Next: If the auger does not clear the clog, proceed to the next step.
Check for Main Sewer Line Issues
Do: Check other drains in your home to see if they are also slow or clogged.
Observe: Multiple drains with issues may indicate a main sewer line problem.
Means: A main sewer line clog may require professional attention.
Next: If other drains are affected, contact a professional plumber.
Inspect Toilet Components
Do: Check the flapper, fill valve, and flush valve for any signs of damage or wear.
Observe: Leaking or worn components may prevent proper flushing.
Means: Toilet components may need repair or replacement.
Next: If components are damaged, consider replacing or repairing them.

FAQ

Why won't my toilet plunge even after using a plunger?

If the toilet still won't plunge after using a plunger, the clog may be too deep or compacted. Try using a toilet auger to reach and remove the blockage.

Can a low water level in the tank cause a toilet not to plunge?

Yes, a low water level can result in insufficient force to flush properly. Adjust the fill valve to ensure the tank is filling to the appropriate level.

What should I do if the toilet auger won't clear the clog?

If the toilet auger is ineffective, it may indicate a more severe blockage in the main sewer line. Contact a professional plumber to inspect and clear the clog.

How can I prevent future clogs in my toilet?

To prevent future clogs, avoid flushing non-flushable items, use toilet paper designed for easy breakdown, and periodically clean the drain with a mild cleaner.

Is it normal for the toilet water level to rise when plunging?

Yes, it is normal for the water level to rise slightly when plunging as it creates pressure to dislodge the clog. However, if the water continues to rise without draining, it may indicate a more serious issue.
