Sewer Cleaning FAQs, answered by experts

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).

The best practice is to clean the sewer drain lines in your home once a year or every two years. Older homes could require more frequent maintenance. Keeping up on cleaning your sewer lines can prevent severe clogs, help ensure your system is working properly, and prevent expensive repairs.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.
