"We could not be happier with the service we were provided with and their pricing was VERY affordable. Finding an honest, family owned business is hard these days, well you have found it. Not only was the owner very, very friendly and informative over the phone, he came to our house during the service call and was one of the NICEST people we have ever met. His workers arrived at the stroke of 7:30am, the exact time we were told, they were super nice, knowledgeable, clean and even texted us beforehand to let us know they were on their way. WE HIGHLY, HIGHLY RECOMMEND THIS COMPANY. They really gave us a great price for emptying our two cesspools and the service was done in a timely manner and our lawn was not left a mess. TWO BIG THUMBS UP! We would definitely use them again in a minute."

"He expertly troubleshooted the low pressure kitchen faucet issue and avoided the need to replace the faucet itself. He neatly replaced the check valve from the sump pump to the sewer drain in a very narrow utility closet. I highly recommend him for your plumbing issues and will use his services in the future."

"I had a water main break at my house. It needed to be taken care of immediately. I found 8995 Sewer Drain through the Angi service. Carl came to the house the same day, looked the work over and gave me an excellent price. He was there the next morning working the job at 7:30am. Knocked it out in no time. Very happy with his workmanship, promptness and pricing. Would definitely use Carl and 8995 again!!!!"

Sewer Cleaning questions, answered by experts

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 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.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

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.

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.
