"I worked with Jesse to help with a clogged bathtub drain after I tried plunging it myself. I explained over the phone that I was dealing with backflow problems and each time I used the bathroom sink the water would end up back in the tub. Unlike another plumber who said they would need to charge me to snake both the tub and the bathroom sink, Jesse explained it would likely just need to be the sink and there is an issue in the shared drainage pipe. Jesse communicated clearly when he'd arrive and on his availabilites, and helped resolve the issue quickly and cleaned up after himself. He also gave me additional advice on how to manage my drainage issues in the future, and another toilet problem I had. Good guy to work with, and got the job done. Would hire again."

"We have an old house (100+ years old). I called Atomic Rooter to fix a bad clog and reconnect drain pipes. They responded quickly, came the next day (as agreed), on time, professional, clean and upfront price. For plumbing services, I think they were very reasonable. Larry and his assistant were great. I will use them again."

"Luke was a great help. Despite not being a typical install, Luke went the extra mile to clean our wood burning stove setup and gave us valuable knowledge for the future. Highly recommend, will be using him again for sure."

Drain Cleaning FAQs, answered by experts

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

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).

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.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.
