"Patrick came the same day we called him, worked hard to open up our clogged sewer and when snaking didn't fix it explained our options in a clear and professional manner. He and his crew were punctual, cleaned up after themselves and did good work. We enjoyed working with Patrick and feel we got a good deal considering everything that needed to be done. When it became clear that we had a serious problem, he quoted us one price for the digging and new clean-out installation and didn't charge us for the initial snake and scope services. He also got the inspector to recommend fixing the sewer under the street, and that was accomplished in a timely manner since a new water main had just been installed on our street and the paving hadn't been completed. We can now feel confident our AirBnB guests will no longer have any plumbing issues!"

"I had a really bad shower and toilet clog so I decided to contact flo-maxx and they sent 2 professionals, Garret and Raymond to do the job but I wasn’t sure if they would be able to clear the drain, they definitely cleared it super quick and also cleaned my floor afterwards. They finally left but there was a small leak from the toilet water line and I called them and they came back again to check it and fix it, no big deal they did great! 10/10"

"The job was done properly, which is of utmost importance. Howver, I had to call because no one arrived or called when the time of the appointment came and went. Apparently, the appointment mistakenly didn't get saved in their schedule. The guys showed up 30 minutes after the scheduled appointment time, which wouldn't be a big deal if it hadn't been before work for me. However, the job was done correctly and with consideration of not wanting me to be late. They offered to come back tomorrow, but I declined. I would hope that more clean-up post work would be done, but, again, I believe the lack of this service was due to the fact that they knew I had to get to work. I would definitely hire them again, but I would request that cleaning be done post as well as confirmation prior to arrival."

"I highly recommend Drain Pros. They’re a family-owned and operated business that truly takes pride in their work. I’ve personally used them and have also recommended them to my 80+ year-old mother, who has used them several times as well. They’ve always been professional, dependable, and most importantly—honest. They never try to upsell her or push unnecessary work. They simply provide exactly what’s needed and do the job right. It’s rare to find a company with this kind of integrity and work ethic these days. I’m always happy with their service and will continue recommending them to friends and family!"

"My situation was particularly difficult, with my drain clean out being in my crawlspace in a cramped spot. Bob really impressed me with his ingenuity, and more importantly his confidence in how to best do the job. Bob and Kevin got my main sewer line cleared and everything cleaned up in 2 hours. I highly recommend R.A. Mechanical."

"Excellent work and fast service. The replacement parts are high quality, but on the pricey side. The service call and labor was great pricing. The employees are very respectful. I will recommend them to others and in the future I will call them for other plumbing issues."

Sewer Cleaning FAQs, answered by experts

If you’re wondering whether rats can come up the toilet, the unfortunate answer is yes, it’s possible, though it’s extremely rare. These rodents are excellent swimmers and can travel through sewer pipes in search of food, and they may follow plumbing lines leading to your home if they’re drawn by the scent of scraps and waste. The toilet’s U-bend holds a small pocket of air, which can help a rat catch its breath before making its final push into your bathroom. While more common in cities with larger rat populations, this can happen anywhere with connected sewer systems; sealing entry points and keeping drains clean can help reduce the risk.

A sewer line should be cleaned at least once every 18 to 22 months. The process takes about 30 minutes or up to 5 hours, depending on the size of the line, how easy it is to access, and how long it’s been since the previous cleaning. If your sewer line hasn’t been cleaned in a couple of years or you don’t even know the last time it’s been cleaned, it’s time to call a pro.

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.

There is conflicting advice on whether to leave a baking soda and vinegar mixture in a drain overnight. Some sources suggest it can be effective for tough clogs, recommending that you flush the drain with warm water in the morning as part of a monthly cleaning routine. However, other experts advise against leaving the mixture in for extended periods, as its caustic nature could corrode drainpipes if used too often or left in for too long.
