If you were to look underneath your house and property, you’d find that all of your drains run to one main sewer line.

This pipe connects your home to a municipal wastewater treatment system or your property’s septic tank.

When it gets clogged, you’ll notice several symptoms start developing in your home.

  • You might hear gurgling sounds when running water down the sink or flushing the toilet.
  • There could be more sewage odors coming from your lower-level drains.
  • Fluid might back up into other drains when you operate a washing machine, dishwasher, or shower.
  • You have multiple slow-running drains without any apparent cause.

Instead of dumping a commercial drain de-clogger into your system, these strategies are reasonable ways to clear a main sewer line.

How to Unclog the Main Sewer Line

Before you can start unclogging the main sewer line, you’ll need to locate the main line drain pipe. It will be somewhere on your property, often near your house. It is a large-diameter pipe that carries the waste from each drain to the primary dispersal method.

If you have a clean-out fitting, it’ll be much easier to remove the clog than if you must access it through your branch plumbing.

You’ll need to loosen the cap for the main line pipe before opening it entirely. A pipe wrench is your best option for this need.Once it is loose, you can follow these steps.

1. Let the clog spill out.

After quickly opening the cap, you’ll want to step back if you have a clogged main sewer line. The buildup will escape through this area. It must run off entirely before you can attempt to fix the problem.

2. Send an auger cable into the pipe.

Since each plumbing snake works a little differently, you’ll need to follow the tool’s instructions. It should get fed gently into the drain pipe until you reach the clog.

You’ll know you’ve reached it because the auger stops moving or becomes more difficult to manage.

3. Run the auger until the clog is clear.

You’ll need to run the plumbing snake until you clear the clog. Once the water level in your pipe starts to lower, you’ll know that it is gone. That doesn’t mean you should stop using the equipment. Push forward to ensure any other problems are gone.

4. Spray it down.

As you remove the plumbing snake, spray it clean with your garden hose. This prevents a smelly mess while ensuring you’ve removed the clog.

Please note that this method works for drain-related clogs only. If you have shrub or tree roots clogging your line, you’ll need to hire a professional.

How to Keep the Main Sewer Line Unclogged

Your best option to manage this resource is to prevent the main sewer line from getting clogged. That means you’ll want to avoid putting any substances that could solidify into your drain.

Items like paint, coffee grounds, and grease can solidify or clump to create blockages.

You’ll also want to watch what gets flushed. Paper towels and facial tissues don’t work the same way as toilet paper, which can increase the risk for future blockages. Even some toilet paper won’t dissolve in water.
