Dealing with a clogged main sewer line can be a nightmare for any homeowner. Not only does it cause inconvenience, but it can also lead to potential damage and health hazards if not addressed promptly. However, with the proper knowledge and tools, you can effectively tackle this issue and restore proper drainage to your home. This comprehensive blog explores various methods and techniques on how to unclog main sewer line.

Understanding the Problem:

Before diving into solutions, it’s essential to understand the common causes of main sewer line clogs. The buildup of grease, hair, soap scum, food particles, tree roots, and foreign objects is among the primary culprits. Identifying the root cause can help you choose the most appropriate method for unclogging the sewer line.

DIY Solutions:

When you’re faced with a clogged main sewer line, it’s natural to want to try and resolve the issue yourself before calling in a professional plumber. Here’s a detailed look at each method:


Plunging is often the first defence against a clogged drain, including the main sewer line. To effectively plunge a sewer line, you’ll need a heavy-duty plunger specifically designed for toilets. Ensure there’s enough water in the toilet bowl to cover the plunger. Place the plunger over the drain opening and create a tight seal. Push and pull the plunger forcefully, maintaining a consistent rhythm. Continue plunging for several minutes, periodically checking to see if the water begins to drain. If successful, plunging can dislodge minor clogs and restore unclogging main sewer line.

Homemade Drain Cleaners:

If you prefer a more natural approach, homemade drain cleaners can be effective for minor clogs. Two popular DIY drain cleaning solutions include:

Baking Soda and Vinegar: 

Start by pouring one cup of baking soda down the drain, followed by one cup of vinegar. Allow the mixture to fizz and bubble for about 30 minutes, then flush the drain with hot water.

Hot Water and Dish Soap: 

Boil a pot of water on the stove, then mix in a few tablespoons of dish soap. Carefully pour the solution down the drain and let it sit for at least 30 minutes before flushing with hot water.

It breaks down grease, soap scum, and other organic matter that contribute to clogs. While they may not be as potent as commercial drain cleaners, they’re safer for your pipes and the environment.

Plumbing Snake:

A plumbing snake, also known as a drain auger, is a versatile tool that can break up stubborn clogs deep into your sewer line. Insert the snake into the drain opening until you feel resistance. Rotate the handle clockwise to feed the snake further into the drain. Once you reach the clog, rotate the handle to break it apart.

Hydro Jetting:

While not strictly a DIY method, hydrojetting involves using high-pressure water to clear out sewer line clogs and is worth mentioning for its effectiveness. However, it’s best left to professionals due to the specialized equipment and safety considerations involved.

Hydrojetting blasts water through the sewer line at high pressure, effectively scouring away grease, debris, and tree roots.
