Why Toilets Get Clogged

Understanding the cause of a clog helps you pick the most effective method to fix it. Common reasons include:

  1. Excessive Toilet Paper – Using too much toilet paper in a single flush is the most common cause of blockages. Modern toilets are more water-efficient and sometimes struggle with large amounts of paper.
  2. Foreign Objects – Kids’ toys, hygiene products, or accidentally flushed items like wipes can block pipes. Even items labeled “flushable” can cause clogs over time.
  3. Hard Water Deposits – Mineral buildup in pipes can reduce water flow, making even normal use susceptible to clogs.
  4. Old or Narrow Pipes – Older homes may have smaller-diameter pipes or plumbing that isn’t compatible with modern toilets.
  5. Septic Tank Issues – For homes with septic systems, a full tank or slow drainage can mimic a clogged toilet.

Understanding the cause is the first step to choosing the right solution.

Tools and Materials You’ll Need

Before tackling a clogged toilet, make sure you have the following:

Tool / MaterialPurpose
Plunger (flange type)Generates suction to remove blockages
Toilet auger (snake)Reaches deep clogs unreachable by a plunger
Rubber glovesProtects hands from bacteria and germs
BucketHelps remove excess water if needed
Dish soapLubricates the blockage and helps break it down
Hot waterHelps dissolve grease or soften paper-based clogs
Towels or ragsFor cleaning spills and splashes

Having these ready saves time and ensures safety during the unclogging process.

Step 1: How to Unclog a Toilet Using a Plunger

The plunger is often the first and most effective tool for minor to moderate clogs.

Step-by-Step:

  1. Put on rubber gloves.
  2. Ensure there’s enough water in the toilet bowl to cover the plunger’s rubber cup. If not, add water.
  3. Position the plunger over the drain, making a tight seal.
  4. Start with slow plunges to avoid splashing, then move to vigorous up-and-down motions for 15–20 seconds.
  5. Pull the plunger away and check if the water drains. Repeat if necessary.

Pro Tips:

  • Keep the plunger submerged to create maximum suction.
  • Avoid excessive force that might crack the toilet bowl.
  • If water begins to rise dangerously, pause and remove some water with a bucket before continuing.

Step 2: Natural Methods Using Dish Soap and Hot Water

For clogs caused by grease, paper, or minor blockages, a natural approach works well:

Step-by-Step:

  1. Pour 1–2 cups of dish soap into the toilet bowl.
  2. Heat 1–2 liters of water to just below boiling. Never pour boiling water directly, as it may crack porcelain.
  3. Pour the hot water from waist height to create pressure in the trap.
  4. Wait 10–20 minutes to let the soap lubricate the blockage.
  5. Try flushing gently. Repeat if needed.

Extra Tips:

  • For thicker blockages, leave the soap and hot water overnight.
  • Combining with a plunger after waiting can improve results.
  • This method is safe for all plumbing types and septic systems.

Step 3: Using a Toilet Auger for Stubborn Blockages

When a plunger or natural method fails, a toilet auger (also called a snake) is necessary:

Step-by-Step:

  1. Insert the auger cable into the drain carefully to avoid scratching the bowl.
  2. Turn the handle clockwise while gently pushing the cable forward.
  3. When resistance is felt, rotate to break up the blockage.
  4. Slowly retract the auger. Flush to confirm the clog is cleared.

Pro Tips:

  • Avoid forcing the cable if resistance is extreme; this may damage the toilet or plumbing.
  • Clean the auger thoroughly after use to prevent bacterial contamination.
  • Augers are ideal for objects stuck deep in the pipe, like toys, wipes, or small hygiene products.

Step 4: Using Chemical Drain Cleaners (Last Resort)

Chemical cleaners can dissolve toilet clogs, but they should be your last option:

Instructions:

  1. Choose a toilet-specific chemical cleaner.
  2. Follow the manufacturer’s instructions carefully.
  3. Avoid mixing with other chemicals.
  4. Wait for the recommended time, then flush.

Cautions:

  • Overuse can corrode pipes, especially older PVC or metal plumbing.
  • Chemicals can be harmful to septic systems and the environment.
  • Always wear gloves and ensure proper ventilation.

Step 5: When to Call a Plumber

Sometimes, even with the best DIY methods, a clog may persist. Call a professional if:

  • The toilet frequently clogs despite proper use.
  • Multiple toilets in your home drain slowly (possible main line blockage).
  • Foreign objects cannot be removed with an auger.
  • You notice foul odors or gurgling sounds.

Professional plumbers have specialized tools like hydro-jetting equipment and camera inspections that can resolve tough clogs safely.

Common Mistakes to Avoid

  1. Flushing inappropriate items – Avoid wipes, feminine hygiene products, paper towels, or small objects.
  2. Overusing chemicals – Can damage plumbing and the environment.
  3. Forcing plungers or augers – May crack porcelain or bend pipes.
  4. Ignoring slow drains – A minor slow drain can turn into a severe blockage if left untreated.
  5. Skipping gloves and safety measures – Hygiene is important when handling toilets.

Prevention Tips for a Healthy Toilet

TipExplanation
Flush only appropriate itemsKeep wipes, paper towels, and non-biodegradable items out
Moderate toilet paper useUse small amounts per flush to avoid buildup
Regular cleaningPrevent mineral and grease buildup
Check pipes periodicallyOlder homes benefit from occasional inspections
Educate family membersTeach children proper flushing habits
Install drain screensPrevent objects from accidentally falling into the toilet

Advanced Tips for Persistent Toilet Issues

  • Water pressure check: Low water pressure can make flushing less effective. Inspect the tank and valves.
  • Pipe inspection: Use a plumber’s camera to identify hidden blockages or root intrusion in older homes.
  • Septic maintenance: If using a septic tank, pump it regularly to avoid backups.
  • Toilet replacement: Older toilets with low flow may struggle with modern usage; upgrading can prevent frequent clogs.
