"Great! John, the owner was super helpful and nice on the phone. Eased all our concerns. The crew, Phil and Tim, showed up right on time and were able to locate the service caps in the lawn in 10 minutes. They showed me clearly how full the tanks were and clearly explained the problem and the solution. The prices quoted were very fair and there were no surprises. It took around 90 minutes. The job was all done outdoors and when they left you would never know it was done. Very neat and professional. The odors, etc we had were gone and we noticed the drains all flowing more freely. Exactly as they said. So glad we had this done before it became a serious and ugly problem inside the house. We highly recommend Priority Cesspool Sewer and Drain. Thank you!"

"We returned from an out-of state Thanksgiving celebration only to find a flooded basement due to a heavily clogged sewer line. We were panicking but Louie responded to our emergency promptly. We found him to be extremely knowledgeable and very professional. He took time to explain the problem and what was needed to solve it and answered all of our questions clearly. It required extreme physical effort for him to clear the sewer drain and it wasn't a pleasant job. But he never gave up until it was done. In doing this he avoided bringing in additional equipment which would add to our cost. His price was fair and he gave us helpful suggestions on how to proceed to the next step in restoring our basement. We are very grateful that we came across him during this emergency and wouldn't hesitate to recommend him to others."

"I thought I only needed a washing machine drain pipe cleared. It turned out to be more extensive than that. They stayed and cleaned out the pipe all the way through my basement. Everything running well now. Reasonable price and they cleaned up completely before they left."

"We had John do our plumbing job. He was excellent. We had a hose that was attached to the outside of our house, that would not come off. We had several people try to take it off, no use. He was able to take it off without breaking the pipe. If i need a plumber again would definitely ask for him."

Sewer Cleaning FAQs, answered by experts

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

Your sewer pro will take about an hour to complete your sewer line camera inspection. However, if your home does not have cleanout access and the pro needs to remove the toilet to access the sewer line, the time to completion will take longer. Note that this estimated time does not include the time for repair, drain cleaning, or any other services you may need. 

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).

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.
