How to Unclog a Toilet

How to Unclog a Toilet

The first step in understanding how to unclog a toilet is to assess its function. If your toilet is not flushing properly, take immediate steps before plunging.

• To keep the toilet from overflowing, either remove the lid of the toilet tank and close the flapper, or turn off the water supply at the shut-off valve.
• Place towels or newspapers on the floor around the toilet in case of splashing.
• If the obstruction is a solid object such as a toy or towel, see if you can remove it by hand.
• Wear rubber gloves before reaching into the toilet bowl or handling any object that has been there.
• If you smell gas, open the bathroom window and contact a plumber immediately, as a sewer issue could be causing the problem.

Tip: Partial clogs may eventually clear themselves, but can also build up to more serious obstructions. It’s easier to clear one sooner rather than later.

How to Plunge a Toilet

Learning how to unclog a toilet with a plunger involves having the right tools. A plunger creates a vacuum to force clogs out of drains. Heavy-duty plungers with ball-shaped heads or rubber flanges are much more effective than conventional cup-shaped ones.

• Ensure the toilet bowl contains enough water to submerge the plunger head.
• Place the plunger over the hole in the toilet and create a seal.
• Plunge up and down rapidly, keeping the plunger submerged, and lift it only slightly on each upstroke.
• Be patient—several plunge cycles may be needed to loosen the clog.
• Flush to test whether the clog has cleared. Repeat if necessary.
• Clean the plunger before returning it to storage.

Tip: Before plunging, run hot water over the plunger to soften the rubber for a better seal.

How to Unclog a Toilet with a Snake

If plunging doesn’t work, try a toilet auger (also called a plumbing snake). This flexible coil extends into pipes to clear obstructions without damaging them.

• Feed the end of the auger into the toilet carefully to avoid scratching the bowl.
• Crank the handle clockwise and push until you either snag or break up the obstruction.
• If you snag something, pull the auger out to remove it.
• Clean the auger after use.

Tip: If you don’t have an auger, you can use an unbent coat hanger or garden hose as a temporary substitute, though it may be less effective.

Not every homeowner owns drain cleaning equipment. You can rent augers and other drain tools from a local hardware store to save money and space.

How to Unclog a Toilet Without a Plunger

If you don’t have a plunger or auger, consider using a chemical or natural drain opener to break down the clog over time.

• Commercial enzyme-based drain cleaners can liquify solid waste when used according to directions.
• Make your own solution by pouring one cup of baking soda and two cups of vinegar into the toilet, then adding half a gallon of hot water. Dish soap can also help loosen obstructions.
• Let the solution sit overnight, then flush to check if the clog has cleared.

Tip: If using a commercial cleaner, ensure it’s made for toilets—some chemicals can damage plumbing. Consider this a last resort before calling a plumber.

Avoid Toilet Clogs

Prevent future toilet clogs by following these tips:

• Do not use excessive amounts of toilet paper. Consider using a bidet for hygiene with less paper.
• Only flush appropriate items—never paper towels, wipes, or sanitary products.
• Keep the water jets under the toilet rim clean for full flushing power. Scrub weekly with a toilet brush.
• Teach small children not to flush toys or other non-flushable items.

Toilet Maintenance Tips

Knowing how to fix a clogged toilet is important, but proper maintenance prevents issues and protects your plumbing.

• Be aware that certain chemicals can harm septic systems. Research products before use.
• Always wear protective gear when using chemical drain cleaners, and never mix products.
• Address clogs quickly—overflowing water can cause damage and health hazards.
• Never pour grease, wax, or similar substances into the toilet; they can solidify and cause clogs.
• Avoid “flushable” wipes—they often block pipes despite the label.

In most cases, using a plunger remains the most effective way to unclog a toilet. If that doesn’t work, try an auger or chemical cleaner before contacting a professional plumber.
