Sewer Cleaning questions, answered by experts

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

Yes. Sewer cameras are invaluable tools that can help pros safely diagnose problems with your septic system. Without a camera to look into your system, septic issue diagnoses would be a combination of guessing and past experience. However, a camera can help confirm ideas that your pro may already have about what’s wrong.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

Even with a high-resolution camera, what you're looking at on the screen may not be recognizable to the untrained eye. Your plumber should be willing to walk you through the video and explain what they found. With high-res images, bright lighting, and self-leveling technology, you should get clear, steady views of the pipes that make up your plumbing system.

One way to save money on sewer lines is to install a sewer cleanout since it makes sewer line maintenance easier. Keeping up with maintenance is key to reducing the cost of repairs, so be sure to schedule annual plumbing inspections, install drain guards to stop objects from accidentally falling down drains, and only flush human waste and toilet paper to protect your pipes.
