How to Unclog a Toilet Trap

A clogged toilet can be one of the most frustrating household plumbing issues. When flushing doesn’t do the trick, the clog is likely in the toilet trap underneath the bowl. Fortunately, unclogging a toilet trap is usually a quick and easy process. With some basic tools and a little elbow grease, you can have your toilet working properly again in no time.

What Causes Clogs in a Toilet Trap?

The S-shaped pipe directly under the toilet bowl is known as the trap. Its purpose is to hold water and create a seal that prevents sewer gases from entering the bathroom. While effective at keeping odors at bay, toilet traps are also prone to getting clogged. Some common culprits include:

Excess toilet paper – Too much paper at once can create a mass that gets stuck.
Flushable wipes – Although marketed as flushable, wipes usually don’t break down and can collect in traps.
Feminine products – Pads and tampons can quickly accumulate in traps.
Condoms – Condoms are not meant to be flushed and tend to get caught in traps.
Toys – Bath toys accidentally dropped down the toilet often block traps.
Hair – Strands of hair combine over time and wind around the trap.
Food – Grease, oils and food scraps flush down but can’t pass the trap.
Foreign objects – Kids may flush toys or small items that get stuck.

No matter the cause, a clogged toilet trap needs to be cleared to restore flushing capabilities.

How to Tell If You Have a Clogged Toilet Trap

There are a few signs that point to a clogged trap versus another toilet issue:

Water backs up and overflows from bowl – This happens when the trap is completely blocked so no water can exit.
Toilet gurgles – An partially clogged trap causes bubbling and noises with flushing.
Poor flush even after plunging – Plunging the bowl doesn’t fix the problem.
Sewer smell – Gases escape into the bathroom from a non-sealed trap.
Toilet bubbles and drains slowly – Water drains but slower than normal.

If you notice any of these issues, inspect the trap for obstructions.

Unclogging a toilet trap involves disassembling the trap itself to physically remove the blockage. This is a straightforward drain cleaning task and most homeowners can tackle it themselves. Here are the step-by-step instructions:

Supplies Needed

Rubber gloves
Old rags or towels
Bucket
Plumber’s snake or wire coat hanger
Channel-type pliers or tongue-and-groove pliers

Step 1: Turn Off Water Supply

Locate the shut-off valve behind or near the toilet and turn it clockwise to shut off the water supply. This prevents spillage while you work.

Step 2: Flush Toilet and Empty Bowl

Flush the toilet one last time and use a small cup to remove any remaining water and debris from the bowl. Place rags or towels on the floor around the base to soak up splashes.

Step 3: Disconnect Water Line

On the bottom rear of the toilet, disconnect the supply line. This flexible tube runs from the valve to the fill valve. Loosen the coupling nut with your pliers and detach it.

Step 4: Loosen Bolts and Remove Toilet

Use a wrench or pliers to loosen the bolts on either side of the toilet base. After unscrewing them, rock the bowl gently side-to-side while lifting up to separate it from the drainpipe. Lift the toilet up off the bolts and set it aside on newspaper or an old towel.

Step 5: Inspect Trap and Locate Clog

With the toilet removed, examine the trap closely to find where the clog is occurring. You’ll see water sitting in the curved trap. Determine if the blockage is near the top, middle or outlet of the trap bend.

Step 6: Dislodge Clog with Snake

Insert your plumber’s snake or wire coat hanger down through the toilet drain opening and make contact with the clog. Push firmly and twist the snake to break up the material and dislodge it down through the trap. Repeat several times until the passage is clear.

Step 7: Clean Out Trap Debris

Reach into the trap wearing gloves and pull out any debris you can get a hold of. Use a small bucket to bail out water and use rags to wipe out any sludge coating the trap walls.

Step 8: Reinstall Toilet

With the trap fully cleared out, you can reset the toilet. Place the bowl back over the bolts and press down to set the wax ring seal. Hand tighten bolts before using a wrench to finalize the connection.

Step 9: Reconnect Water Supply

Reattach the flexible supply line to the fill valve and turn the shut-off valve counterclockwise to restore water supply to the toilet.

Step 10: Test Toilet and Flush

With everything back in place, turn on the water and flush the toilet a few times to verify normal operation. Let the bowl refill and check for any leaks underneath.

Tips for Preventing Clogged Toilet Traps

Clogged traps aren’t unavoidable but you can take some simple precautions to minimize the chances of dealing with one:

Never flush wipes or other unflushable items – stick to toilet paper only.
Install a toilet paper holder close to the bowl to discourage using too much paper.
Invest in a hair catcher that fits inside drains to collect strands before they clog traps.
Pour a kettle of hot water down the drain weekly to melt grease and keep drains clear.
Limit bathroom toys that could fall into the toilet and get stuck.
Remind kids not to flush foreign objects down the toilet.
Have your sewer line professionally cleaned every other year to remove tree roots and buildup.

When to Call a Plumber

While many toilet trap clogs can be removed DIY-style, there are instances when it’s best to call a professional:

You can’t find the clog location in the trap.
The clog is very dense or compacted into trap.
Toilet repairs are beyond your mechanical abilities.
You need trap replacement versus just cleaning.
Sewer drain backups occur frequently.
Multiple bathroom fixtures are affected.

A qualified plumber like [plumber name] has the expertise and equipment to fully diagnose toilet issues and correct trap clogs that are stubborn or challenging to reach. Don’t hesitate to call for help avoiding frustration and prevent additional complications.

Understanding what causes obstructions, how to pinpoint issues, using proper tools, and disassembling the trap components allows you to thoroughly remove blockages. Remember to always turn off toilet water supply lines prior to any work. With a few basic maintenance habits, you can avoid many clogged trap occurrences altogether. But if problems persist or repairs are beyond your skill level, rely on a professional plumber to correctly handle toilet clogs and keep your bathroom happily flushing.

FAQ About Unclogging a Toilet Trap

Here are answers to some frequently asked questions about unclogging toilet traps:

All standard flush toilets have an S-shaped trap as part of their design located just below the bowl. Traps can be plastic or brass and hold water to prevent sewer gas from entering the bathroom.

What is the easiest way to unclog a toilet trap?

The quickest method is to disassemble the trap and manually remove debris causing a clog. With the toilet removed, you have full access to clean out the trap bend. A wire snake can also be inserted through the drain to help break up clogs.

How do you unclog a toilet without a plunger?
