"Jack did an excellent job with replacing the sewer pump. He offered helpful advice in diagnosing the issue and selecting the pump. After the job was done, he even sent his guys over again to install a second valve with no charge to fix a minor issue. Thank you, Jack, for a wonderful job!!!!"

"Edgar and Bill, and their assistant did an outstanding job. The complete replacement of the sewer line at the home I just bought was a day-long job. The technicians were thorough, careful, professional, respectful, and friendly. I will definitely know who to call if (God forbid) I ever need a big job done! Definitely an A+ from me."

"I needed my outdoor shower/bath plumbing redirected due to a collapsed pipe. Zach diagnosed the problem and offered two options depending on what he found. He arrived on time and got the job done in a day and cleaned up well. Overall a really good experience."

"Was unable to establish blockage of sewer route from inside. Come to find out that the coduit of both home/city piping, 30yo pvc from yard was shattered to pieces from a local contractor that hanitually parked his truck on the burial site at the side of the drive. Thanked these reps for their best service allowable at the time. Took hiring an outside- literally- contractor to dig up and replace my sewer from house to street and reroute pipes of both meeting points so this was less of a future issue."

"Zoom Drain is a company that I would use again. I needed a gas line removed and a duct vent relocated in my laundry room, zoom drain came, assessed the job and gave me a reasonable price to fit the job. Jonathan was very professional and polite, he explained in detail what he would have to do how long the job would take and made sure he addressed all of my questions. I didn’t feel pressured to hire them on the spot, he allowed me time to speak to my husband and set a date for the job. Upon walking me through the job Jonathan pointed out to me plumbing problems that I had from work that another company had just done and I told him my concerns with the work that was done and with no questions asked he told me he would fix it for me. I really appreciate when I get workers who are honest and really want to do the job and do it correctly and this company has shown me that I can trust and count on them to do the job."

"Bradley went above and beyond in helping me updating the plumbing in my old home. He very quickly identified many issues with little information from me and provided recommended next steps after just one walkthrough. He also went out of his way to explain everything he was doing in a simple and easy to understand way that really put me at ease. All of that at extremely fair pricing. I would highly recommend Bradley and I will be referring him to my friends and family if/when they need plumbing work."

Sewer Cleaning FAQs, answered by experts

A professional drain cleaner is a plumber or specialized drain cleaner with the necessary tools to unclog drains and tiles to keep waste water flowing out to the septic tank or city sewer for processing. Keeping wastewater from backing up into your home helps keep you and your family safe from potential contamination and sickness. These pros can help resolve nearly any drain situation in a safe and efficient manner.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

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 one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

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.
