A clogged toilet is one of those plumbing problems that demands immediate attention. Whether it’s a partial blockage causing slow flushing or a complete stoppage with water threatening to overflow, knowing how to respond quickly can prevent water damage and unnecessary stress. As Upland’s trusted local plumbers, we’ve compiled everything you need to know about handling a clogged toilet — and when to pick up the phone and call a professional.
Common Causes of a Clogged Toilet
Not all toilet clogs are created equal. Understanding the cause can help you determine the right solution:
- Too much toilet paper flushed at once
- Non-flushable items — wipes, cotton pads, feminine hygiene products, paper towels
- Children’s toys or small objects accidentally dropped in
- Hard water mineral buildup narrowing the drain over time
- A blockage deep in the main sewer line affecting all fixtures
If the cause is a single flush gone wrong, a plunger may be all you need. If blockages are recurring or multiple toilets are affected, the issue likely runs deeper.
Step-by-Step: How to Unclog a Toilet
Step 1 — Stop Overflow Immediately
If the toilet bowl is near the rim, do not flush again. Instead, remove the tank lid and push down the flapper valve to stop water from entering the bowl. This buys you time to address the clog without making a mess.
Step 2 — Use a Flange Plunger
A flange (or toilet) plunger — with its extended rubber bell — creates a better seal than a flat cup plunger. Submerge the plunger in the bowl water, position it firmly over the drain opening, and push and pull rhythmically 10–15 times. Keep the suction seal intact throughout. After several attempts, try flushing to see if the clog has cleared.
Step 3 — Try a Toilet Auger
If the plunger doesn’t work, a toilet auger (also called a closet snake) can reach further into the drain to break up or retrieve the obstruction. Feed the coiled cable into the toilet drain, rotate the handle clockwise, and advance until you feel resistance. Work the auger back and forth to break up the clog, then retrieve and flush.
Step 4 — Know When to Stop
If you’ve tried both a plunger and a toilet auger without success, stop. Continued attempts can damage the toilet’s porcelain or push the obstruction deeper into the pipe. This is the point to call a professional plumber.
Warning Signs That Point to a Bigger Problem
Sometimes a clogged toilet is a symptom of a larger plumbing issue. Call Upland Plumbers at 1-800-905-7115 right away if you notice:
- Multiple toilets or drains are slow or clogged at the same time
- Gurgling sounds from sinks or tubs when you flush
- Sewage odors indoors or in your yard
- Water backing up into the shower or bathtub when you flush
- Recurring clogs that return within days
These are classic warning signs of a main line sewer blockage — a serious issue that requires professional hydro-jetting or sewer line repair.
What to Avoid When Dealing with a Clogged Toilet
- Do NOT use chemical drain cleaners in a toilet — they are rarely effective and can damage porcelain and pipes
- Do NOT flush repeatedly — this only risks an overflow and can worsen the blockage
- Do NOT ignore the problem — a partial clog almost always becomes a complete one
- Do NOT use a standard cup plunger — it won’t create the seal needed for a toilet bowl
