How to Unclog a Toilet: A Quick & Easy Guide
A clogged toilet is a common problem you can usually fix yourself without calling a plumber. Follow these simple steps to get things flowing again.
Step 1: Stop the Toilet from Overflowing!
Before you do anything else, prevent a watery mess.
- Don't flush again. This will only add more water to the bowl.
- Remove the tank lid.
- Close the flapper. Press down on the rubber flapper at the bottom of the tank to stop water from entering the bowl.
- Turn off the water supply. Turn the small valve on the wall behind the toilet clockwise until it stops.
If the bowl is very full, use a small bucket to bail out some water, leaving enough to cover a plunger.
Method 1: Use a Plunger (The Right Way)
This is the most effective method for most clogs.
- Use the right tool: You need a flanged plunger (with a rubber lip), not a simple cup plunger.
- Get a good seal: Place the plunger in the bowl and ensure the flange is sealed over the drain opening. The plunger should be covered with water.
- Plunge correctly: Push down gently to release air, then begin plunging with firm, steady up-and-down strokes for about 20-30 seconds. The upward pull is just as important as the downward push.
- Break the seal: After plunging, pull the plunger away quickly. The water should rush down the drain.
If it works, turn the water supply back on and try a test flush. If not, try plunging one more time before moving to the next method.
Pro Tip
The upward motion is key - don't just push down. The suction created when pulling up is what dislodges most clogs.
Method 2: Dish Soap and Hot Water
This gentle method can help break down organic waste and paper clogs.
- Pour about 1/2 cup of dish soap into the toilet bowl.
- Add hot water. Let a gallon of hot (not boiling) water from the tap run into the bowl. Pouring from waist height adds force. Never use boiling water, as it can crack the porcelain.
- Wait 20-30 minutes. The soap and hot water will help dissolve the clog.
- Try flushing.
Method 3: Baking Soda and Vinegar
This creates a fizzing reaction that can dislodge blockages.
- Add 1 cup of baking soda to the toilet bowl.
- Slowly pour in 2 cups of white vinegar.
- Let it sit for 30-60 minutes.
- Follow with hot water and try flushing.
When to Call a Plumber
If you've tried these methods and the clog won't budge, or if you notice these signs, it's time to call a professional:
- Multiple drains (toilets, sinks, showers) are clogged at once.
- Water backs up into other fixtures when you flush.
- You hear gurgling sounds from other drains.
- You suspect a foreign object (like a toy) is stuck.
- The problem happens frequently.
How to Prevent Future Clogs
- Only flush human waste and toilet paper.
- Do NOT flush: paper towels, wipes (even "flushable" ones), feminine products, cotton swabs, dental floss, or hair.
- Use a reasonable amount of toilet paper.
