A step-by-step guide to obstructing sewer systems
1. Find a clean out of your sewer system
Most homes have a main sewer cleanout with direct access to the sewer line. Typically, this cleanout is:
- Just outside the foundation of your home, often near the bathroom or kitchen
- Basement (in some old houses)
- Near the street or sidewalk, depending on the local code
Tip: Cleanouts are usually identified by round or square caps labeled “cleanout” or “sewer.”
2. Carefully open the clean out
- Place a bucket or sheet of plastic around the clean-out cap to catch any spills.
- Use a pipe wrench or an adjustable wrench slowly Loosen the clean-out cap.
- Stand sideways to avoid potential sewage overflows. Loosen the cap and if you want to hear or see the liquid under pressure, tighten it again and wait for it to sink before proceeding.
3. Use a plumbing auger or drainage snake
- Insert the auger: Push the end of the drain snake into the clean-out until resistance occurs.
- Working with the auger: Rotate the handle or switch the motor (for electric snakes) to the motor to break through or latch the clog.
- Work through a clog: Gently move the auger back and forth to remove any debris. Pull the auger out from time to time to remove any waste that is trapped between the cables.
- Reinsert if necessary: Repeat the process until you can no longer feel any resistance on the line.
Pro tips: Do not force the cable too aggressively as the blockage is solid or if the pipe is weakened by corrosion or tree roots this can damage the piping.
4. Wash off the lines
After disbanding or removing obstacles:
- Install the garden hose Slowly drain the line towards the source of water to wash away any remaining debris.
- Observe the flow: If water flows smoothly through the cleanout, the clog may be cleared.
5. Test the drain
- Secure the clean-out cap Return to its original position.
- Turn on the water Make sure that multiple equipment throughout your home (sinks, bathtubs, toilets) are all drained properly.

Prevents future sewer blockages
Preventive maintenance is key to avoiding backups of sewer lines and protecting property.

FAQs about sewer clogged systems
Can I use a chemical drain cleaner to interfere with the sewer line?

Hydrojets are effective and safe for most modern sewer pipes. However, if the system is very old or severely damaged, high-pressure water can exacerbate existing weaknesses. Always consult a professional first.
What happens if I can’t find a sewer clean-out?
If you are unable to find a clean-out for your property, check your home inspection report or contact your local plumber. In some municipalities, clean-outs may be located near sidewalks and streets.
