Dealing with a clogged sewer line is more than just an inconvenience—it can lead to backups, foul odors, and costly water damage. The good news is that you may be able to tackle the issue yourself. Whether you reside in a house in Philadelphia or a duplex in Kansas City, there are steps you can take to address mild to moderate clogs on your own. In this Redfin blog post, you’ll discover how to safely and efficiently unclog a sewer line without the need to call a professional.
Signs of a Clogged Sewer Line
Recognizing the early warning signs of a sewer line clog can help you address the issue before it escalates. Common indicators include:
- Multiple drains backing up: If more than one drain in your home is overflowing or draining slowly, the main sewer line may be blocked.
- Gurgling noises: Hearing gurgling or bubbling sounds when using water fixtures can indicate a clog in the sewer line.
- Foul odors: A strong, unpleasant smell coming from drains could signal improper wastewater flow through the sewer line.
- Water backup in lower fixtures: Water backup in lower-level plumbing fixtures may indicate a clog in the main line.
Safety Precautions and Preparations
Before attempting any DIY sewer line unclogging project, make sure to take proper safety measures:
- Wear protective gear: Use heavy-duty gloves, protective eyewear, and rubber boots to avoid contact with sewage and bacteria.
- Shut off water: Turn off the main water supply if possible to reduce the risk of water damage and sewage overflow.
- Ventilate the area: Open windows or use fans to disperse fumes and odors.
- Gather proper tools: Have the necessary equipment on hand to streamline the unclogging process and minimize health risks.
Essential Tools and Materials
To effectively unclog your sewer line, you will likely need the following tools and supplies:
- Pipe wrench or adjustable wrench: For opening and closing the main sewer cleanout cap.
- Plumbing auger (drain snake): A tool designed to break through or retrieve blockages in the sewer pipe.
- Garden hose: For flushing out loosened debris.
- Bucket or plastic sheeting: To contain any water or sewage that overflows during the unclogging process.
- Protective gear: Including heavy-duty gloves, rubber boots, goggles, and a face mask.
- Flashlight: For inspecting inside the cleanout for obstructions.
Pro Tip: For extensive tree root intrusion or severely damaged pipes, specialized tools like a mechanical root cutter or hydro jetting equipment may be necessary and best handled by a professional.
Step-by-Step Guide to Unclog a Sewer Line
1. Locate the Sewer Cleanout
Most homes have a main sewer cleanout that provides direct access to the sewer line. The cleanout is typically located:
- Just outside the home’s foundation, often near the bathroom or kitchen
- In the basement of older homes
- Near the street or sidewalk based on local codes
Tip: Look for a round or square cap labeled “cleanout” or “sewer” to identify the cleanout.
2. Open the Cleanout Carefully
- Place a bucket or plastic sheeting around the cleanout cap to catch any spillage.
- Use a pipe wrench or adjustable wrench to slowly loosen the cleanout cap.
- Stand to the side to avoid potential sewage overflow. If fluid under pressure is observed when the cap is loosened, tighten it back and wait for the pressure to subside.
3. Use a Plumbing Auger or Drain Snake
- Insert the auger: Push the drain snake into the cleanout until resistance is encountered.
- Engage the auger: Rotate the handle or activate the motor to break through or latch onto the clog.
- Work through the clog: Move the auger back and forth to dislodge debris. Periodically remove waste caught on the cable.
- Re-insert if needed: Repeat the process until no resistance is felt in the line.
Pro Tip: Avoid forcefully pushing the cable, as it can damage the piping if the blockage is solid or the pipe is weakened.
4. Flush the Line
After breaking up or removing the obstruction:
- Attach a garden hose to a water source and run water through the line to flush out remaining debris.
- Observe the flow: If water flows smoothly through the cleanout, the clog is likely cleared.
5. Test Your Drains
- Secure the cleanout cap back in place.
- Turn on water in multiple fixtures to ensure proper drainage.
- Check for gurgling noises, sluggish drainage, or water backup.
When to Seek Professional Help
If DIY efforts fail or you suspect severe damage, it’s best to call a licensed plumber. Professionals can offer services such as:
- Video camera inspections to locate hard-to-reach clogs or pipe damage.
- Hydro jetting for clearing stubborn or extensive clogs.
- Pipe repair or replacement for severely damaged pipes.

- Avoid flushing problematic items like paper towels or sanitary items.
- Use enzyme-based treatments to keep drains clear.
- Monitor tree roots near the sewer line for intrusion.
