Toilet Clogged? Do This First.
If the water is rising in the bowl, don’t flush again. That second flush is often what causes bathroom floods. Here’s what to do right now:
- Lift the tank lid and push the flapper valve down to stop water from flowing into the bowl.
- Turn the shutoff valve (behind the toilet near the floor) clockwise until it stops. This cuts the water supply completely.
- Lay towels around the base of the toilet in case water has already spilled over.
Once the water has stopped rising, you have time to work through the fix without pressure.
Before You Start Working
- Put on rubber gloves and safety glasses. Toilet water carries bacteria. You don’t want splashback in your eyes or on open cuts.
- Lay old towels or newspapers around the base of the toilet before you start plunging, not after. It’s much easier to prevent a mess than to clean one up.
- If the bowl is brim-full, use a disposable cup or old container to bail some water into a bucket first. Plunging a full bowl splashes dirty water across the bathroom. Get the water level down to about halfway before you start.
How to Tell if Your Toilet is Clogged
Not every slow flush is a full clog. Here are the signs that something is actually blocking the drain:
- The water rises instead of draining after you flush, or it sits in the bowl much longer than normal.
- You hear gurgling sounds from the shower or bathtub drain when the toilet is flushed. This means water is struggling to get through.
- Water backs up in other fixtures. If flushing the toilet sends water into your shower, or running the washing machine makes the toilet bubble, the blockage may be deeper in the drain line, not just in the toilet itself.
- You see water near the sewer cleanout outside your home. This points to a main line backup, not just a toilet clog.
If water is backing up in multiple fixtures at once, that usually means the main sewer line is blocked, not just the toilet. A plunger won’t fix that. Call Staggs Plumbing at 682-284-0966 for a drain inspection before the problem gets worse.
Fix It With a Plunger (The Right Way)
A toilet plunger is usually all you need. They cost less than $10 at any hardware store. Make sure you have a flange plunger (the kind with a soft rubber extension below the cup). Flat cup plungers are for sinks and won’t seal properly over a toilet drain.
Step by Step:
- Make sure there’s enough water in the bowl to cover the plunger cup. If the bowl is nearly empty, add some water with a bucket. You need water, not air, to create pressure against the clog.
- Place the plunger over the drain opening and press down slowly to push the air out of the cup. You want a tight seal.
- Pump firmly 3 to 4 times with short, fast strokes. Keep the seal tight. You should feel resistance.
- Pull the plunger away sharply on the last stroke. If the clog breaks loose, you’ll hear the water rush down the drain.
- Flush the toilet to confirm the water flows freely. Run two full flushes to make sure everything clears.
Most simple clogs (toilet paper, waste buildup) will clear with this method on the first or second attempt.
Important: If you can see a hard object (a toy, toothbrush, bottle cap) lodged in the drain, do not plunge. Plunging pushes it deeper into the trap or drain line where it becomes much harder to retrieve. Fish it out by hand or with a wire hanger instead.
No Plunger? Try These Home Methods
If you don’t have a plunger and the hardware store is closed, here are some methods that can work on minor clogs. These are best for soft blockages (too much paper, waste). They won’t clear hard objects like toys or thick wipe buildups.
Hot Water and Dish Soap
Squirt a generous amount of liquid dish soap into the bowl. Then pour in a bucket of hot (not boiling) water from about waist height. The soap lubricates the blockage and the weight of the water pushes it through. Wait 10 to 15 minutes, then flush.
Do not use boiling water. It can crack the porcelain.
Baking Soda and Vinegar
Pour about one cup of baking soda into the bowl, followed by two cups of white vinegar. It will fizz. Let it sit for 20 to 30 minutes, then follow with a bucket of hot water. This can break up organic blockages, but it’s slower and less reliable than a plunger.
Wire Coat Hanger
Untwist a wire coat hanger and straighten it out, leaving a small hook at one end. Wrap the hook end with a rag or tape to avoid scratching the porcelain. Feed it into the drain and gently work it around to break up or hook the clog. This is basically a makeshift auger and works surprisingly well on soft blockages close to the drain opening.
Wet/Dry Shop Vac
If you have a wet/dry shop vac in the garage, set it to liquid mode and use it to suck the clog out. Place the hose directly over the drain opening and create a tight seal. The suction can pull out blockages that plunging can’t budge. Never use a regular household vacuum for this. Only a wet/dry shop vac is designed to handle liquids.
Be Honest About What Works
These methods have a lower success rate than a plunger. They work best on partial clogs where water is still draining slowly. If the bowl is completely backed up and nothing is moving, save yourself the time and get a plunger or an auger.
If you’re on a septic system: The baking soda and vinegar method is septic-safe. Chemical drain openers are not. Harsh chemicals kill the beneficial bacteria in your septic tank that break down waste.
When the Plunger Doesn’t Work: Use a Toilet Auger
If plunging hasn’t cleared it after 10 to 15 solid attempts, the blockage is probably deeper in the trap or drain line. This is where a toilet auger (also called a closet auger) comes in.
A toilet auger has a flexible cable inside a protective tube that feeds into the drain without scratching the porcelain. You can rent one from most hardware stores or buy one for $20 to $40.
How to Use a Toilet Auger
- Insert the curved end of the auger into the toilet drain opening. The rubber boot sits against the bowl.
- Crank the handle clockwise while pushing the cable forward. You’ll feel resistance when you reach the clog.
- Keep cranking through the resistance. The auger either breaks the blockage apart or hooks onto it so you can pull it out.
- Retract the cable slowly and check if the clog comes out with it. If it’s a hard object (toy, bottle cap), retrieve it. Don’t try to push it further down the line.
- Flush the toilet two or three times to verify the drain is clear.
If the auger doesn’t reach the blockage, or you hit resistance far down the line, the problem is likely past the toilet’s trap and into the drain or sewer pipe. This is the point to stop the DIY and call a licensed plumber. Forcing a longer snake or power auger without experience can damage pipes. Call Staggs Plumbing at 682-284-0966 for a professional assessment.
Why Does My Toilet Keep Clogging?
If you’re dealing with repeat clogs, there’s usually a reason beyond “too much paper.” Here are the most common causes:
- Older low-flow toilet. First-generation low-flow toilets (installed in the mid-1990s to early 2000s) often lack the flushing power to clear waste properly. Modern low-flow models have much better flush performance. If your toilet was installed 20+ years ago and clogs regularly, replacing it may be cheaper than repeat service calls.
- Blocked toilet trap. The S-shaped trap built into every toilet is designed to hold water and block sewer gas. But that curve also catches objects. Toys, wads of paper, paper towels, and feminine products are the usual culprits. A plunger or auger can clear most trap blockages.
- Partially blocked drain line. If the clog is past the toilet and in the drain pipe, you’ll often notice other fixtures acting up too (slow tub drain, gurgling in the shower). Old pipes damaged by tree roots, foundation movement, or age can restrict flow even if there’s no single blockage. In the DFW area, expansive clay soil puts extra stress on underground pipes.
- Main sewer line problem. When multiple fixtures back up at the same time, the problem is almost always in the main sewer line. Root intrusion, pipe collapse, and bellied (sagging) sewer lines are common in North Texas homes built in the 1970s and 1980s.
- Non-flushable items. Products labeled “flushable” (like wipes) are one of the most common causes of repeat clogs. They don’t break down like toilet paper. The same goes for feminine products, cotton swabs, and dental floss.
What You Should Never Flush Down the Toilet
The only things that should go into your toilet are human waste and toilet paper. Everything else belongs in the trash. Here’s the most common list of items that cause clogs:
- “Flushable” wipes
- Paper towels
- Napkins
- Feminine products
- Cotton balls or swabs
- Dental floss
- Hair
- Diapers
- Medicine or pills
- Plastic of any kind
If you have kids, keep the toilet lid closed and consider a child lock. Curious kids flushing toys is one of the most common calls we get.
Is Drain Cleaner Safe for Toilets?
Most chemical drain cleaners (like Drano, Liquid-Plumr, and similar products) are not recommended for toilets. Here’s why:
- They generate heat. Chemical drain cleaners create an exothermic reaction. In the confined space of a toilet trap, this heat can crack the porcelain or damage the wax ring seal underneath.
- They don’t work well on toilet clogs. These products are designed for hair and grease in sink and shower drains. Most toilet clogs are solid blockages (paper, waste, objects) that chemicals can’t dissolve effectively.
- They make the problem harder to fix. If the chemical doesn’t clear the clog, you now have a bowl full of caustic liquid that makes plunging or augering unsafe. A plumber will need to neutralize or drain the chemicals before working on it.
Stick with a plunger, hot water and dish soap, or an auger. If those don’t work, a plumber will fix it faster and safer than any chemical product.
What About Enzyme Cleaners?
Enzyme-based drain cleaners (like Green Gobbler or RID-X) are a safer alternative. They use natural bacteria to eat away organic buildup over time. They won’t clear an active clog the way a plunger will, but they’re good for monthly maintenance to keep drain lines flowing. They’re also septic-safe, which matters if you’re on a septic system.
Is It Actually a Clog? Troubleshooting Weak Flushes
Sometimes what looks like a clog is actually a mechanical problem inside the tank. If the toilet flushes weakly every time (not just occasionally), try these checks before reaching for the plunger:
The Bucket Flush Test
Pour a full bucket of water rapidly into the bowl. If the water flushes down with force, the drain is clear. The problem is in the tank (the flapper, chain, or fill valve), not the drain. If the bucket flush is also slow, you have a real blockage.
Check the Tank Water Level
Lift the tank lid and look at the water line. It should be about an inch below the top of the overflow tube. If the water level is low, the toilet doesn’t have enough volume to create a strong flush. Adjust the fill valve or float to raise the water level to the correct mark.
Clean the Rim Jets
Look under the rim of the bowl. You’ll see small holes (rim jets) where water flows during a flush. Over time, mineral deposits from hard water build up in these holes and restrict flow. In North Texas, where water is typically 18+ grains per gallon hard, this happens faster than in most areas. Use a small wire, stiff brush, or a bent paper clip to clear each hole. You can also pour white vinegar under the rim and let it soak for a few hours to dissolve the buildup.
When to Call a Plumber for a Clogged Toilet
Most single-event toilet clogs are an easy DIY fix. But some situations need professional equipment and experience. Call a plumber if:
- The plunger and auger both failed. The blockage is likely past the toilet’s trap and into the drain or sewer pipe. Professional drain snakes and hydro jetting equipment can reach further and clear tougher obstructions.
- Multiple fixtures are backing up. When the toilet, shower, and sink all act up at the same time, the problem is in the main sewer line. This requires a sewer camera inspection to find the exact location and cause.
- The toilet clogs every week or two. Repeat clogs usually indicate a partially blocked drain line, root intrusion, or a toilet that needs to be replaced. A professional diagnosis saves you from an endless cycle of plunging.
- You see or smell sewage outside. If wastewater is surfacing near a cleanout or in the yard, the sewer line has a serious blockage or break. This isn’t a toilet problem anymore.
- A hard object is stuck. Toys, bottle caps, and other solid items can lodge in the trap or beyond. Attempting to force them through with a snake can damage the pipe. A plumber can retrieve the object or remove the toilet to access it from below.
What to Expect When a Plumber Fixes Your Clogged Toilet
Knowing what happens during a service call can take the stress out of calling. Here’s how Staggs Plumbing handles a typical clogged toilet visit:
- We diagnose before we fix. Our technician will check whether the blockage is in the toilet, the drain line, or the sewer main. If it’s past the toilet, we use a sewer camera to locate the exact problem.
- We show you what we find. If we run a camera inspection, you’ll see the video. We explain what’s causing the issue and give you options, not a single “take it or leave it” price.
- Pricing is upfront. We quote a flat rate on a tablet before any work starts. No surprises. The price includes labor, parts, and cleanup.
- We clean up after ourselves. Shoe covers go on before we enter your home. Drop cloths go down around the work area. We leave the bathroom the way we found it.
Most clogged toilet service calls take 30 minutes to an hour. If the problem turns out to be a main line blockage, we’ll explain the additional work and cost before proceeding.
