Sewer Cleaning FAQs, answered by experts

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

The type of clog in your sewer main determines the required cleaning method. Different types or methods of sewer main cleaning require various tools like chemicals, mechanical removal, or a combination of both. Some of the most common types of sewer main line cleaning include:

  • Minor debris removal: $100–$600

  • Tree root removal: $100–$1,000

  • Trenchless pipe repair: $60–$250 per linear foot

  • General line repairs: $1,000–$4,000

  • Full pipe replacement: $3,000–$25,000
