How to Unblock a Badly Blocked Toilet?

Dealing with a badly blocked toilet can be frustrating, but with the right approach, you can resolve the issue effectively. Here’s how Delta Plumbers would suggest unblocking a badly blocked toilet:

Assess the Severity:

Before taking any action, assess the severity of the blockage. If the toilet is completely backed up and overflowing, it’s crucial to stop the flow of water to prevent flooding. Locate the shut-off valve near the base of the toilet and turn it clockwise to stop the water flow.

Use a Plunger:

A plunger is often the first tool to use when attempting to clear a toilet blockage. Make sure the plunger completely covers the drain opening and creates a tight seal. Push and pull the plunger vigorously to create suction and dislodge the blockage. Repeat this several times until the water begins to drain.

Try a Toilet Auger:

If the plunger doesn’t work, a toilet auger, also known as a plumber’s snake, can be used to reach deeper blockages. Insert the auger into the toilet bowl and crank the handle clockwise to extend the cable down the drain. Once you feel resistance, rotate the auger handle to break up the blockage. Slowly retract the auger and flush the toilet to see if the blockage has cleared.

Use a Chemical Drain Cleaner:

If mechanical methods fail to clear the blockage, you may consider using a chemical drain cleaner specifically formulated for toilets. Follow the manufacturer’s instructions carefully and use protective gloves and eyewear when handling chemical cleaners. Pour the recommended amount of cleaner into the toilet bowl and allow it to work for the specified time before flushing.

Seek Professional Help:

If all DIY methods fail to unblock the toilet, it’s time to call a professional plumber from Delta Plumbers. Experienced plumbers have the tools and expertise to tackle even the most stubborn blockages safely and effectively. They can identify the root cause of the blockage and implement the appropriate solution to restore proper function to your toilet.

By following these steps, you can effectively unblock a badly blocked toilet and restore normal function to your plumbing system. However, if you’re unsure or uncomfortable with the process, don’t hesitate to contact Delta Plumbers for professional assistance.

Will a Toilet Eventually Unclog - Delta Plumbers

Will a Toilet Eventually Unclog?

In many cases, a toilet will eventually unclog, especially if the blockage is minor or temporary. However, this is not always the case, and several factors can influence whether or not a toilet will unclog on its own:

Nature of the Blockage:

The type and severity of the blockage play a significant role in determining whether a toilet will unclog on its own. Minor blockages caused by excess toilet paper or organic matter may dissolve or dislodge over time as water continues to flow through the drain. However, more severe blockages, such as those caused by foreign objects or solid waste, are less likely to clear without intervention.

Water Flow:

The rate at which water flows through the toilet can affect the unclogging process. If the toilet is used regularly and water continues to flow through the drain, there is a greater chance that the blockage will eventually break up or dislodge. Conversely, if the toilet is not used frequently or if water flow is restricted due to a partial blockage, it may take longer for the blockage to clear.

Additional Attempts to Unclog:

If initial attempts to unclog the toilet are unsuccessful, further efforts may be needed to resolve the issue. Using a plunger, toilet auger, or chemical drain cleaner can help dislodge stubborn blockages and facilitate the unclogging process. Without intervention, however, the blockage may persist indefinitely.

Underlying Issues: Sometimes, a persistently clogged toilet may indicate underlying plumbing problems, such as a damaged or obstructed sewer line. In such cases, the blockage may not be clear on its own, and professional assistance from a plumber may be necessary to diagnose and address the root cause of the issue.

In summary, while some minor toilet blockages may eventually clear on their own with continued water flow, more severe or persistent blockages often require intervention to resolve. If you’re dealing with a stubbornly clogged toilet, it’s best to take proactive steps to address the issue rather than wait for it to resolve on its own.

What Dissolves Toilet Blockage - Delta Plumbers

What Dissolves Toilet Blockage?

Several methods can be used to dissolve toilet blockages, depending on the cause and severity of the blockage. Here are some common substances and techniques that can help dissolve toilet blockages:

Hot Water:

Pouring hot water into the toilet bowl can sometimes help dissolve or soften blockages caused by organic matter, such as toilet paper or waste. The heat can break down the material and make it easier to flush away. It’s essential to use hot (but not boiling) water to avoid damaging the toilet bowl or plumbing.

Baking Soda and Vinegar:

A mixture of baking soda and vinegar can create a fizzy reaction that may help break up blockages and clear drains. Pour one cup of baking soda followed by one cup of vinegar into the toilet bowl. Let the mixture sit for several minutes, then flush the toilet to see if the blockage has cleared.

Commercial Drain Cleaners:

Chemical drain cleaners are available at most hardware stores and supermarkets and can be effective at dissolving toilet blockages caused by organic matter, grease, or other substances. However, these products contain harsh chemicals that can be harmful to the environment and may damage plumbing if used improperly. It’s essential to follow the manufacturer’s instructions carefully and use these products with caution.

Enzyme-Based Cleaners:

Enzyme-based drain cleaners use natural enzymes to break down organic matter and clear blockages without harsh chemicals. These cleaners are generally safer for the environment and less likely to damage plumbing than traditional chemical cleaners. However, they may take longer to work and may not be as effective on stubborn blockages.

Hydrogen Peroxide:

Hydrogen peroxide can help break down organic matter and dissolve toilet blockages. Pouring hydrogen peroxide into the toilet bowl and allowing it to sit for several hours or overnight may help loosen the blockage and make it easier to flush away.

Plumbing Snake or Auger:

For more stubborn blockages, using a plumbing snake or auger may be necessary to physically break up the blockage and clear the drain. These tools can be inserted into the toilet drain and maneuvered to dislodge the blockage manually.

Professional Plumbing Services:

In cases where home remedies and DIY methods are ineffective, or if there is a more significant underlying issue causing the blockage, it may be necessary to call a professional plumber. Plumbers have specialized tools and equipment to diagnose and address stubborn toilet blockages safely and effectively.

It’s essential to use caution when attempting to dissolve toilet blockages and to avoid using methods or substances that could damage plumbing or pose health risks. If you’re unsure about how to proceed or if DIY methods are unsuccessful, it’s best to seek professional assistance from a licensed plumber.

Why Won't My Toilet Unclog with a Plunger - Delta Plumbers

Why Won’t My Toilet Unclog with a Plunger?

If your toilet won’t unclog with a plunger, it could be due to several reasons:

Insufficient Force:

Plunging requires a significant amount of force to dislodge the blockage. If you’re not applying enough force or if the seal around the plunger is not airtight, it may not generate enough pressure to clear the clog.

Improper Technique:

Plunging requires a specific technique to be effective. If you’re not using the plunger correctly—for example, if you’re not creating a tight seal around the drain or if you’re plunging too forcefully or too shallowly—it may not be effective at clearing the clog.

Hardened Blockage:

If the blockage is caused by hardened materials such as toilet paper, waste, or foreign objects, plunging alone may not be enough to dislodge it. In such cases, you may need to use additional methods such as using a plumbing snake or auger to break up the blockage manually.

Deep Blockage:

If the blockage is located deep within the drain or sewer line, plunging may not be sufficient to reach and dislodge it. In such cases, you may need to use more advanced techniques or equipment, such as a toilet auger or a professional plumbing service, to clear the blockage effectively.

Underlying Plumbing Issues:

Persistent toilet clogs that are resistant to plunging may be a sign of underlying plumbing issues, such as tree root infiltration, damaged sewer lines, or improper drain slope or venting. In such cases, it’s essential to address the root cause of the problem to prevent future clogs and potential damage to your plumbing system.

If your toilet won’t unclog with a plunger despite your best efforts, it may be time to consider other methods or seek professional assistance from a licensed plumber. A plumber can diagnose the underlying issue and recommend the most appropriate solution to clear the clog and restore proper toilet function.

What Happens if You Leave a Toilet Clogged for Too Long - Delta Plumbers

Picture Source – Delta Plumbers

What Happens if You Leave a Toilet Clogged for Too Long?

Leaving a toilet clogged for an extended period can lead to several undesirable consequences:

Worsening of the Clog:

Over time, the materials causing the clog can harden or become more compacted, making it increasingly challenging to remove them. This can exacerbate the clog and make it more difficult to clear using standard methods such as plunging or snaking.

Foul Odors:

Standing water in the toilet bowl combined with decomposing waste can emit foul odors that permeate the bathroom and nearby areas. These odors can be unpleasant and may indicate the presence of bacteria and other harmful microorganisms.

Bacterial Growth:

Stagnant water in a clogged toilet provides an ideal environment for bacterial growth. Bacteria from human waste can multiply rapidly, increasing the risk of contamination and potential health hazards if the bacteria spread to other surfaces or come into contact with skin.

Water Damage:

If the clog causes the toilet bowl to overflow, it can lead to water damage to the surrounding floor, walls, and fixtures. Prolonged exposure to water can weaken structures, promote mold growth, and cause costly damage that requires professional repair.


A clogged toilet is inconvenient to use and can disrupt daily routines, especially in households with limited bathroom facilities. It can cause frustration and inconvenience for occupants, particularly if multiple attempts to unclog the toilet are unsuccessful.

Risk of Plumbing Damage:

Continuously flushing a clogged toilet in an attempt to clear the blockage can strain the plumbing system and increase the risk of damage to pipes, fittings, and other components. This can result in leaks, burst pipes, or other plumbing issues that require repair or replacement.

Overall, leaving a blocked toilet for too long can lead to a host of problems, ranging from unpleasant odors and bacterial growth to water damage and plumbing issues. It’s essential to address toilet clogs promptly to prevent these issues and maintain a safe and sanitary bathroom environment. If standard methods fail to clear the clog, it’s advisable to seek professional assistance from a licensed plumber to avoid further complications.
