How to Unclog Main Sewer Line With a Snake

Dealing with a clogged main sewer line can be a stressful and messy situation, but using a plumbing snake is an effective way to resolve the issue. A plumbing snake, also known as an auger, is a tool designed to break through blockages and clear out debris causing the clog. Knowing how to properly use a snake can save time and money, as well as the need to call a professional plumber.

This guide on how to unclog main sewer line with a snake will walk you through the process step-by-step, ensuring you can tackle the problem with confidence and care.

Why Use a Plumbing Snake?

A plumbing snake is highly effective in clearing clogs because it can reach deeper into pipes than other tools. This allows the snake to break through and clear out blockages, ensuring that water flow is restored quickly.

Additionally, using a plumbing snake is much more cost-effective and environmentally friendly compared to using chemical drain cleaners. These cleaners contain harsh chemicals that can damage your pipes and are harmful to the environment.

What You Will Need

Before starting, make sure you have all the necessary tools and equipment to effectively use a plumbing snake:

A plumbing Snake:

This can be purchased at any hardware or home improvement store. Make sure to choose a snake that is long enough to reach the main sewer line.

Rubber Gloves:

It is important to protect your hands from any debris or bacteria that may be in the pipes. Wearing rubber gloves will also give you a better grip on the snake as you maneuver it through the pipes.

Safety Glasses:

Clogs can cause water to splash back, and wearing safety glasses will prevent anything from getting into your eyes.

8 Step-by-step Guides on How to Unclog Main Sewer Line With a Snake

Step 1: Locate the Main Sewer Line Access Point 

Begin by identifying the main sewer line access point, which is typically referred to as the cleanout. The cleanout is a capped pipe that provides direct access to the sewer line and is usually located outside your home, near the foundation. Alternatively, it may be found in a basement, crawl space, or utility area. Look for a round or square cover that is labeled or slightly elevated.

Once located, clear the area around the cleanout to ensure you have sufficient space to work safely and comfortably.

Step 2: Prepare the Plumbing Snake

Before inserting the snake into the cleanout, make sure it is set in the right direction. The end of the snake with the auger head should be facing towards where you will be feeding it into the pipe.

Next, ensure that you have a firm grip on both ends of the snake and turn it on if using an electric model. If using a manual snake, rotate it clockwise to extend its length.

Step 3: Insert the Snake Into the Pipe 

Carefully feed the end of the snake into the cleanout access point. Push the snake into the pipe slowly and steadily, allowing it to follow the natural path of the sewer line. If you encounter resistance, do not force the snake; instead, rotate it clockwise to help the auger head move through bends or initial blockages.

Continue feeding the snake into the pipe until you reach the suspected location of the clog. Be patient and avoid rushing this step to prevent damaging the snake or the sewer line.

Step 4: Break Through the Clog 

Once the snake reaches the clog, you will feel resistance as you attempt to push it further. Begin rotating the snake clockwise while gently pushing it forward. This rotating motion helps the auger head grab onto or break apart the debris causing the blockage. If the snake is electric, switch it to its operating mode to enhance the cleaning action. 

Continue rotating and maneuvering the snake until you feel the resistance lessen, indicating that the clog is starting to break up. For particularly stubborn blockages, you may need to pull the snake back slightly and reinsert it several times to fully dislodge the debris. Be careful not to apply too much force, as this could damage the pipes. Once the clog is cleared, proceed to the next step to ensure the line is fully clean.  

Step 5: Remove the Snake From the Pipe 

After successfully breaking through the clog, carefully begin retracting the snake from the pipe. Slowly pull the snake out to avoid splashing or spreading any debris that may have been collected on the auger head. If using a manual snake, continue rotating it clockwise as you withdraw it to help prevent the snake from getting stuck or tangled inside the pipe. 

Once the snake is fully removed, check the auger head for any debris or remnants of the clog. Clean the snake thoroughly before storing it, as this will prevent the buildup of residue and ensure it’s ready for future use. 

Step 6: Test the Water Flow 

After removing the snake and cleaning the area, it’s time to check if the clog has been fully cleared. Turn on a faucet or run a hose that connects to the cleared sewer line. Allow the water to flow through the system and observe whether it drains smoothly without any backups or slow draining. 

If the water flows normally, this indicates that the blockage has been successfully removed. However, if water is still not draining properly, there may be an additional or more severe blockage further down the line. Repeat the snaking process if necessary, or consider consulting a professional plumber if the issue persists. Once satisfied with the water flow, turn off the faucet or hose and wipe down the cleanout area. Proceed to the final steps to complete the process.   

Step 7: Flush the System 

To ensure that any remaining debris, residue, or bacteria is flushed out of the system, run hot water down the drain for a few minutes. Hot water helps to melt and dissolve any grease or oils that may be present in your pipes.

Additionally, you can pour some baking soda followed by vinegar into the drain to help break down any remaining buildup further. Flushing the system will also help eliminate any unpleasant odors caused by clogs. 

Step 8: Prevent Future Clogs

Prevention is key when it comes to maintaining clear and functional sewer lines. To prevent future clogs, try implementing these simple tips:

• Avoid pouring fats, oils, and grease down the drain, as they can solidify and cause blockages.
• Use a hair strainer in your shower or bathtub to catch loose hair before it goes down the drain.
• Regularly clean out your kitchen sink disposal by grinding ice cubes and citrus peels to help remove any buildup.
• Consider scheduling regular professional drain cleaning services for a thorough deep cleaning of your plumbing system. 

By following these steps on how to unclog main sewer line with a snake and implementing preventative measures, you can successfully unclog your main sewer line with a snake. Remember to always use caution when working with plumbing tools and materials, and don’t hesitate to seek professional assistance if needed. With proper maintenance and care, you can keep your sewer line clear and your plumbing system functioning properly for years to come. Happy snaking!

Additional Tips

• If you encounter a particularly stubborn clog that cannot be cleared with a snake, it may be a sign of a more serious issue such as tree roots invading your sewer line. In this case, it is best to consult a professional plumber for proper diagnosis and repair.
• Always wear protective gear such as gloves and safety glasses when handling plumbing tools and materials.
• Regularly inspect and maintain your sewer line to catch any potential clogs or issues before they become severe.
• If unsure about using a snake or experiencing difficulty with the process, do not hesitate to call a professional for assistance. It is better to be safe than risk causing further damage to your plumbing system. 
• In addition to using a snake, you can also try using a hydrometer or chemical drain cleaners as alternative methods for unclogging your main sewer line. However, these methods should only be used by trained professionals as they can cause damage if not used correctly.
• Consider investing in a power auger snake for tougher clogs, as it offers more power and maneuverability than manual snakes.
• Always read the instructions and safety precautions before using any plumbing tools or chemicals.

Frequently Asked Questions

Q: Can I Use a Snake to Unclog Other Drains Besides the Main Sewer Line?
