Sewer Cleaning FAQs, answered by experts

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

In most states, companies that perform sewer cleaning services don’t need specific licensing, but you should always ensure you hire a licensed and certified plumber to get the work done. You can use our state licensing tool to check whether the potential sewer cleaning company holds a plumber’s certification and license. Hiring a certified sewer cleaning services guarantees that the work will be done safely, there won’t be additional damage done to your home, and the problem will be fixed.

A sewer cleanout typically looks like a white or gray PVC pipe with a removable cap. It's often located either in your yard or basement, depending on your home's plumbing configuration. The cleanout pipe is designed to provide easy access to your sewer system for maintenance and inspections. It may be flush with the ground or slightly elevated, making it distinguishable from other pipes. When you remove the cap, you can access the sewer line directly or determine its direction, which can be helpful when you need to locate your sewer line from your house to the street.

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.
