How do I clean my main sewer line?

Main sewer line cleaning requires professional equipment and expertise - this isn't a DIY job for homeowners. The main sewer line runs from your house to the city connection and requires specialized tools like sewer cameras, hydro jetters, and heavy-duty drain snakes that only licensed plumbers have access to.

Professional sewer cleaning typically starts with a camera inspection to identify the exact problem - whether it's tree roots, grease buildup, collapsed sections, or foreign objects. In Ottawa's older neighborhoods, tree roots are a common culprit, especially with mature maples and willows whose roots seek out the moisture in sewer lines. The camera inspection costs $200-$350 but saves money by pinpointing the issue instead of guessing.

The actual cleaning method depends on what's found during inspection. For minor blockages, professional drain snakes can clear the line ($300-$500). For stubborn root intrusions or heavy buildup, hydro jetting uses high-pressure water to scour the pipe walls clean ($350-$600). Tree roots may require cutting tools followed by chemical root treatment to prevent quick regrowth.

Ottawa's clay and cast iron sewer lines, common in older homes, are particularly susceptible to root intrusion and may need annual maintenance. Signs you need main sewer cleaning include multiple drains backing up simultaneously, gurgling sounds from toilets when other drains are used, or sewage odors in your basement. If you're experiencing sewer backup, stop using water immediately to prevent contamination.

The best prevention is having your main sewer line inspected and cleaned every 2-3 years, especially if you have mature trees on your property.
