8 Step-by-step Guidelines on How to Clean Sewer Line
Step 1: Identify the Main Sewer Line

The first step in cleaning your sewer line is to locate the main sewer line in your home. This is typically a large pipe, often made of PVC or metal, that connects your home’s plumbing system to the municipal sewer or septic system. You can usually find it in your basement, crawlspace, garage, or near the perimeter of your home.
Look for a capped pipe or cleanout access point that is designed for maintenance purposes. Identifying the correct line is essential to ensure you’re addressing the source of the problem and avoiding unnecessary work on unrelated pipes. If you’re unsure, it’s best to consult a professional plumber.
Step 2: Prepare Your Work Area
Cleaning your sewer line can be a messy job, so it’s essential to prepare your work area beforehand. Put on protective gear such as gloves, face masks, and eyewear to avoid contact with any potentially harmful bacteria or chemicals.
Additionally, lay down drop cloths or old towels around the pipes and clean access points to protect your flooring from any spills or splashes. It’s also a good idea to have a bucket on hand to collect debris and water during the cleaning process.
Step 3: Clear Debris From Cleanout Access Point
Once your work area is prepared, carefully remove the cap from the cleanout access point. Use a wrench or pliers if necessary, but proceed slowly to avoid sudden releases of pressure. Once the cap is removed, you may notice a buildup of debris, such as dirt, grease, or waste, near the opening. Use a gloved hand or a small scooping tool to gently clear away any visible debris.

Place the removed material into a bucket for proper disposal. Clearing this initial blockage can help determine the severity of the clog and ensure that the cleaning tools, such as a plumber’s snake or water jetter, can be inserted without obstruction. Be cautious of any strong odors or standing water that may escape and proceed carefully to avoid creating a mess.
Step 4: Use a Plumber’s Snake or Auger
A plumber’s snake, also known as an auger, is a long, flexible metal cable with a corkscrew tip
g blockages from pipes. Insert the snake into the cleanout access point and gently feed it down the pipe until you reach the blockage.
Slowly turn the handle of the snake clockwise while pushing it further into the pipe. This action should grab onto and remove any obstructions, such as hair, grease, or tree roots. Continue to feed and turn the snake until it moves freely through the pipe.
Step 5: Utilize a High-pressure Water Jetter
If a plumber’s snake doesn’t completely clear the blockage, you may need to use a high-pressure water jetter. This tool uses a powerful stream of water to dislodge and flush away stubborn debris from your sewer line.
Attach the jetter’s hose to your cleanout access point and turn on the water supply. Slowly insert the nozzle into the pipe, allowing it to navigate through bends and turns while blasting away any remaining buildup. Once the water flows freely through the pipe, remove the jetter and stop the water supply.
Step 6: Flush Out Your Pipes with Water
After using a plumber’s snake or water jetter, it’s essential to flush your pipes out with clean water. This helps to remove any remaining debris or chemicals and ensures that your pipes are entirely clear.

Slowly pour a large bucket of clean water down the cleanout access point, allowing it to flow through the pipe and into your sewer system or septic tank. Repeat this process until there is no longer any debris or residue in the water.
Step 7: Check for Proper Wastewater Flow
Once you have completed the cleaning process and flushed out the pipes, it’s crucial to check for proper wastewater flow to ensure the blockage has been fully cleared. To do this, run water through various fixtures in your home, such as sinks, bathtubs, and toilets. Observe how quickly the water flows down the drains and listen for any unusual gurgling noises or signs of slow drainage.
If the water drains smoothly without backups or delays, your sewer line is likely clear and functioning efficiently. However, if you still notice issues, there may be a more significant obstruction or damage deeper within the line, in which case you should contact a professional plumber for further assessment. Regularly monitoring wastewater flow after cleaning can also help detect potential problems early and maintain a fully operational plumbing system.
Step 8: Schedule Regular Maintenance
Regular maintenance is key to keeping your sewer line clean and preventing future clogs and backups. It’s recommended to have a professional plumber inspect and clean your sewer line at least once every two years or more frequently if you have older pipes or are experiencing frequent blockages.
Additionally, be mindful of what you flush down your drains and toilets, as certain items like grease, wipes, and feminine hygiene products can cause clogs and damage to your sewer line over time. By following these guidelines on how to clean sewer line and scheduling regular maintenance, you can keep your sewer line in optimal condition and avoid costly repairs in the long run.

Frequently Asked Questions

Q: How Can I Prevent Future Sewer Line Clogs?
A: To prevent future clogs, avoid flushing anything other than toilet paper down your toilets and properly dispose of grease and food scraps in the trash instead of down the drain.

Overall, being mindful of what goes into your plumbing system can save you time and money in the long run.
Q: Should I Attempt to Clean My Sewer Line Myself or Hire a Professional?
