"I called Rescue Rooter to come out and clear out a blockage in my sewer line. Chad and Albert came out quickly and got to work. They also put a camera down into the sewer line and had me watch as they went through the line. I saw the various problems in our one hundred year old sewer line. They spent a good deal of time examining the sewer line and also identifying the spot where it becomes a shared line with our neighbor. They presented a number of options of how to repair the deteriorating sewer line along with the different prices for that work. Chad and Albert both explained the different options clearly to my wife and I. They were very friendly and professional."

"Our downstairs toilet, shower and sinks were backing up. We called Drain Pro and they arrived shortly after to look at the problem. They scoped the sewer line with a camera and found a big blockage that was caused by roots. They were able to clear the blockage. Everything is now working great. We will have them back in the future to re pipe the area where the roots have started coming thru. This company is great!!!"

"I payed $4k for them to start connecting my sewer on about Aug. 22. When I called them on Sept 1 to see if they had ordered a needed part to get started, they said they had not got my check yet. The next day they said, *oh we just got it in the mail*. Really? Now it is Sept 8 and they still have not contacted me to say they are ready to start. Their sewer guy is very knowledgeable, but I think their office is confused."

Sewer Cleaning FAQs, 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 cases, drain cleaners will not clear a clogged sewer line, and they’re likely to damage your plumbing. Sewer lines are several inches wide, meaning any material that clogs it will need to be large. Drain cleaner can work on small clogs, but it usually won’t clear a larger one in a sewer main. Drain cleaners can also easily damage and corrode your plumbing with prolonged contact, and a clog will keep the cleaner in contact with the pipes for an extended period. Hire a professional sewer cleaner instead for a safe fix.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

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.

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.
