Why Toilets Get Clogged

To effectively approach the unclogging process, it’s helpful to understand why clogs happen in the first place. Here are some common reasons:

Common Reasons Why Toilets Get Clogged

Understanding the root cause of a toilet clog is essential for preventing it in the future. Here are some of the most common reasons your toilet might get clogged:

Flushing Non-Flushable Items

One of the main reasons toilets get clogged is flushing items that aren’t meant to go down the drain. Wet wipes, even the ones labeled “flushable,” feminine hygiene products, paper towels, and dental floss can stick together or get caught in the narrow pipes, leading to blockages.

Excessive Toilet Paper Use

While toilet paper is designed to break down in water, using too much at once can create clumps that fail to move smoothly through the plumbing system. This is especially problematic in older systems with narrower pipes.

Low-Flow Toilets

Low-flow toilets, particularly older models from the 1990s during the first wave of water-saving designs, may not have enough flushing power to flush waste and paper effectively, leading to frequent clogs.

Blocked Toilet Trap

The S-shaped trap within the toilet is designed to hold water and prevent sewer gases from entering your home. However, it’s also a common place where clogs occur, especially when items like toys, hair, or other debris are accidentally flushed.

Issues with the Sewer Line

Sometimes, the problem doesn’t lie within the toilet itself but rather in the sewer line. Tree roots, broken pipes, or an excessive build-up of debris in the sewer line can obstruct the flow of waste, causing the toilet to back up.

Hard Water Build-Up

If your home has hard water, mineral deposits may accumulate in the toilet’s drains and pipes over time. These deposits narrow the pipes, making it harder for waste to pass through and increasing the risk of clogs.

Faulty Plumbing or Installation

Improperly installed toilets or pipes with poor alignment can cause frequent clogs. If the pipes are too narrow or aren’t at the correct slope, waste may not flow properly, leading to blockages.

By understanding these common causes, you can take proactive measures to prevent clogs in your toilet. Simple habits like only flushing toilet paper and ensuring regular plumbing maintenance can go a long way in maintaining a clog-free bathroom.

Now that we understand the problem let’s jump into the most effective steps to address it.

Method 1: The Basic Plunge

The plunger is a classic and reliable tool for resolving most toilet blockages.

Steps:

  1. Check for Enough Standing Water: Make sure there’s enough water in the toilet bowl to cover the rubber part of the plunger. If it’s too low, carefully pour warm water into the bowl from a bucket.
  2. Create a Good Seal: Position the plunger over the drain hole, ensuring an airtight seal. The cup of the plunger should completely cover the hole to maximize pressure.
  3. Plunge with Force: Hold the plunger with both hands and push down firmly, then pull back. Repeat this step about 10-15 times or until the water starts to drain.
  4. Check the Drain: Once the clog is dislodged, flush the toilet. Watch carefully to ensure the water flows normally.

Tip:

For stubborn clogs, try using a flange plunger, which is specifically designed for toilets and can provide more pressure than a traditional cup-style plunger.

Method 2: Hot Water and Dish Soap

When you don’t have a plunger handy, you can unclog a toilet with items you probably already have in your home.

Steps:

  1. Add Dish Soap: Pour about ½ cup of dish soap directly into the toilet bowl. The soap will help dissolve grease and break down the clog.
  2. Carefully Pour Hot Water: Heat water until it’s hot but not boiling (water that’s too hot can crack your toilet bowl). Carefully pour the water from waist height into the bowl to create pressure that may dislodge the clog.
  3. Wait and Flush: Allow the mixture to sit for about 15-20 minutes, then flush the toilet. If the water drains slowly, repeat the steps until the clog is cleared.

Note:

Never use boiling water, as it may damage the porcelain of the toilet.

Method 3: Baking Soda and Vinegar

This natural solution is ideal for breaking down blockages caused by organic matter.

Steps:

  1. Combine Ingredients: Pour 1 cup of baking soda into the toilet bowl, followed by 2 cups of vinegar.
  2. Wait and Watch: Allow the bubbling reaction to work its magic. This chemical reaction can help dissolve and loosen the clog.
  3. Add Warm Water: After 10-15 minutes, pour warm (not boiling) water into the bowl.
  4. Flush: Check if the water drains properly. If not, repeat the steps.

Method 4: Use a Wire Coat Hanger (For Stubborn Clogs)

If the above methods don’t work, it’s time to bring out simple tools, such as a wire coat hanger.

Steps:

  1. Prepare the Hanger: Straighten a wire coat hanger, leaving a small hook on one end. Wrap the hook in a plastic bag for a softer edge to prevent scratching the toilet bowl.
  2. Access the Clog: Gently push the hanger into the drain to access the blockage.
  3. Dislodge the Clog: Carefully maneuver the wire around to break up or pull out the clog.
  4. Flush and Clean: Once the water starts draining, flush the toilet. Wipe down the hanger before properly disposing of it.

Method 5: Use a Toilet Auger or Plumber’s Snake

For severe clogs that can’t be cleared with plunging or home remedies, a toilet auger or plumber’s snake can reach much deeper into the toilet trap.

Steps:

  1. Insert the Auger: Follow the manufacturer’s instructions carefully to insert the auger into the toilet bowl.
  2. Crank and Push: Use the crank to extend the auger into the toilet’s drain, breaking apart or hooking onto the clog.
  3. Pull Out the Clog: Carefully pull out the auger and any debris.
  4. Flush the Toilet: Test the drain with a gentle flush. You may need to repeat this process for larger blockages.

Preventing Future Clogs

While it’s great to know how to unclog a toilet when disaster strikes, prevention is always the best policy. Here are a few tips:

  • Avoid flushing non-flushable items like wipes, tissues, or hygiene products.
  • Use only the recommended amount of toilet paper.
  • Perform routine maintenance by periodically flushing a mixture of baking soda and vinegar to keep drains clear.
  • Invest in high-quality plumbing tools, such as a good plunger and a toilet auger, for emergencies.
