How to Dissolve Toilet Paper in Septic Tank

For many homeowners, the potential for toilet paper buildup in the septic tank can be a major concern.

Part of everyday life, toilet paper usage is unavoidable, but there are ways to ensure it dissolves properly to prevent clogs and maintain the overall efficiency of your septic system.

Quick Answer:

To aid toilet paper dissolution in a septic tank, utilize bacterial septic treatments, which effectively break down paper and waste. Regularly pump your tank every 2-5 years for maintenance. Use only septic-safe toilet paper in limited amounts to prevent clogging. Never flush anything other than human waste and toilet paper.

By implementing these suggestions and understanding how your septic system works, you can help prolong the life of your septic tank and avoid costly repairs. Proper care and maintenance can also lead to fewer environmental impacts – a win-win for both you and our planet.

Understanding Septic Tanks and Toilet Paper

What is a Septic Tank?

A septic tank is an underground chamber, typically made of concrete, fiberglass, or plastic, that collects and treats wastewater from a household or building. When wastewater enters the septic tank, it naturally separates into three layers.

The top layer consists of fats, oils, and grease, which float to the surface and form a scum layer. The middle layer comprises mostly water, called effluent, and the bottom layer consists of heavier solids, called sludge.

Septic Tanks Process:

  1. Wastewater flows into the septic tank.
  2. Heavy solids settle to the bottom, forming sludge.
  3. Lighter solids, fats, and oils float to the top, creating a scum layer.
  4. The effluent in the middle layer flows out into the drain field.

The Role of Toilet Paper in Septic Systems

Toilet paper is an essential component of daily hygiene but can impact the overall function of your septic system. It’s designed to dissolve and break down when flushed, so it doesn’t clog pipes or interfere with the septic tank’s operation.

However, not all toilet paper is created equal, and some may break down more quickly than others.

When selecting toilet paper for a septic system, consider the following factors:

  • Thickness: Opt for single or double-ply toilet paper, as they typically break down faster than the thicker varieties.
  • Biodegradability: Look for septic-safe or biodegradable toilet paper, which is specially designed to dissolve more easily in septic systems.
  • Usage: Moderating toilet paper usage can significantly impact the health of your septic tank. Use only the necessary amount and avoid flushing anything other than toilet paper down the toilet, such as wet wipes or tissues.

Biodegradable Toilet Paper

Biodegradable toilet paper is made from materials that break down easily and quickly in septic systems. This type of toilet paper is typically made from plant-based materials, such as bamboo, sugarcane, or fast-growing trees, making it gentler for the environment.

Using biodegradable toilet paper can help prevent issues in septic tanks, such as clogs or build-up because the paper decomposes more rapidly than traditional toilet paper.

This allows it to pass through the septic system more efficiently, reducing the risk of issues.

Recycled Toilet Paper

Recycled toilet paper is another environmentally friendly option for septic systems. This type of toilet paper is made from recycled paper materials, such as office paper, newspaper, and cardboard. By using recycled materials, the production process conserves resources and reduces waste.

Recycled toilet paper is often septic tank-safe, as it tends to break down quickly, similar to biodegradable toilet paper. Brands like Seventh Generation offer recycled toilet paper options that are specifically designed for septic systems, ensuring that they are safe and efficient for use.

Septic-Safe Toilet Paper

Septic-safe toilet paper is specifically designed to dissolve and break down quickly in septic systems. This type of toilet paper can be made from a variety of materials, such as virgin paper, recycled materials, or even biodegradable materials.

When choosing septic-safe toilet paper, look for labels or certifications that indicate the paper is suitable for septic systems. This can help ensure that the toilet paper you are using will not cause issues or damage to your septic tank.

How to Dissolve Toilet Paper

There are several ways to dissolve toilet paper in a septic tank.

Using Baking Soda and Vinegar

To dissolve toilet paper using this method, follow these steps:

  1. Mix one cup of baking soda and two cups of white vinegar in a large container.
  2. Pour the solution into the toilet bowl and let it sit for at least 30 minutes.
  3. After 30 minutes, flush the toilet to dissolve the toilet paper and move the solution through the septic system.

Baking soda and vinegar work together to break down the toilet paper in your septic tank. The baking soda helps to neutralize the acids in the toilet paper, while the vinegar contains acetic acid that helps dissolve the paper.

Flush with Hot Water

Another method to dissolve toilet paper in your septic tank is by using hot water. To do this, follow these steps:

  1. Boil a large pot of water on your stovetop.
  2. Once the water reaches a rolling boil, carefully pour it into your toilet bowl.
  3. Immediately flush the toilet to dissolve the toilet paper and move the hot water through the system.

Hot water helps to break down toilet paper by loosening up the fibers and making it easier for the septic system to dissolve. Be cautious when handling boiling water to avoid burns or accidents.

Common Septic System Issues and Solutions

Dealing with Clogged Pipes

Clogged pipes can cause major problems within your septic system. One common cause of clogs is excessive toilet paper buildup. To address this issue, use a plunger to unclog the pipes. If the clog persists, consider calling a professional for assistance.

It’s important to avoid using harsh chemicals, as they can damage your septic system. Instead, opt for environmentally-friendly options such as biodegradable toilet paper to reduce the likelihood of clogs.

Items to Avoid Flushing in a Septic System

Paper Towels and Facial Tissues

Avoid flushing paper towels and facial tissues down the toilet, as they don’t break down easily in a septic system. These products are thicker than toilet paper and can lead to clogs, which can ultimately cause unpleasant smells and damage to the septic system.

Flushable Wipes and Baby Wipes

Despite their name, flushable wipes and baby wipes should not be flushed in a septic system. They don’t decompose as quickly as toilet paper and can cause blockages.

Wet wipes are especially harmful, as they can contribute to the formation of “fatbergs” – large masses of wet wipes and other non-degradable items in the septic tank.

Tampons and Pads

Tampons and pads should also be kept out of your septic system. They can expand and become lodged in pipes, leading to clogs and potential damage. Instead, dispose of these items in the trash or use a designated sanitary disposal container.

Septic Tank Maintenance Tips

Regular Inspections

As a homeowner, it is essential to perform regular inspections of your septic tank to ensure its smooth functioning. This helps in the early identification of any potential plumbing issues and prevents damage caused by overflow or backed-up sewage.

Generally, it is recommended to inspect your septic tank at least once every 1-3 years, depending on the tank size and usage.

To maintain your septic tank efficiently, consider the following tips:

  • Check for clogs: Look for any visible signs of clogs in the tank and the plumbing system. Unclogging the pipes can help in avoiding the accumulation of excess toilet paper.
  • Measure sludge levels: Periodically measuring the sludge levels helps in determining when it’s time to pump and clean the tank.
  • Examine the drain field: Regularly inspect the drain field for any signs of leakage or saturation, which might require remediation.


Proper cleaning of the septic tank is crucial for its efficient functioning. It not only helps in dissolving toilet paper but also prevents unpleasant odors and costly cleaning fees in the long run. Here are some cleaning tips for maintaining your septic tank:

  • Pump the tank: It’s essential to pump your septic tank every 3-5 years, depending on the size and usage, to prevent sludge buildup and ensure smooth draining.
  • Use septic-safe products: Avoid using harsh chemicals or bleach as they can disrupt the balance of bacteria in the tank, which is crucial for breaking down waste materials, including toilet paper.
  • Limit water usage: Conserving water helps in reducing the load on the septic system and allows it enough time to break down and dissolve toilet paper.

By following these septic tank maintenance tips, homeowners can ensure their septic system’s longevity and avoid any potential plumbing issues.
