"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!"

"Okay. So there was a problem with the sewage pump, water in tub and toilet would not go down. The first person to show up after contacting Home Advisor was Mikey from BestFlo. Panicked, I said okay, you can do the job. Awhile later he said it was fixed, and walked away following the repair leaving the area a watery mess with the burnt out equipment, and all the lights on. (I?m not going to even mention the dirt tracked into my house from his shoes.) Honestly I was so angry and distraught about the situation (btw - strictly forbidden disposable wipes were the cause of this $1K expensive repair job) that shortly afterward I went to bed, leaving the cleanup to others in the home. The next morning after taking a shower the toilet would not flush properly, and there was overflowing water [AGAIN] from the replaced sewage pump. I called Sunday 4/19 and was told that someone would appear Monday 4/20 btwn 9:30 - 10:30.am. At 10:40 Mikey reappeared, went to examine the area, quickly adjusted something with the plugs, the system restarted, the toilet automatically flushed, and everything appeared fine. No charge for the revisit. The replaced equipment is guaranteed for only a year. :-( In summary, you can use this company if you wish; just read my review once or twice again before making your choice. Needless to say, my review is quite less than enthusiastic."

"He expertly troubleshooted the low pressure kitchen faucet issue and avoided the need to replace the faucet itself. He neatly replaced the check valve from the sump pump to the sewer drain in a very narrow utility closet. I highly recommend him for your plumbing issues and will use his services in the future."

"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 had a water main break at my house. It needed to be taken care of immediately. I found 8995 Sewer Drain through the Angi service. Carl came to the house the same day, looked the work over and gave me an excellent price. He was there the next morning working the job at 7:30am. Knocked it out in no time. Very happy with his workmanship, promptness and pricing. Would definitely use Carl and 8995 again!!!!"

"The two gentlemen from All Island Sewer and Drain arrived promptly, assessed the condition of my sewer main and methodically cleared out the pipe. They provided excellent craftsmanship and service by integrating modern technology (high quality video imaging) with state of the art “electric snake” to clear the blockage. They also identified the source of the problem (a partially ruptured sewer pipe under my lawn) which will be addressed at a later date. Their fees were also very reasonable. The work area was left in pristine condition and I will definitely be calling them back, to make the permanent repairs when I’m ready…truly a first class organization. Thank you also to Dominic for the quick response…my family is grateful 🙏🏽."

Sewer Cleaning FAQs, answered by experts

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary. 

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.

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.

It is generally safe to stay in a house that smells like sewage for a short time, but you should get the problem fixed as soon as possible. While the level of sewer gas is usually low enough to only cause minor symptoms, prolonged inhalation can lead to headaches, nausea, or respiratory irritation. High levels of gas exposure can be more dangerous, and high concentrations of methane—a component of sewer gas—can pose an explosion risk in enclosed spaces. If you smell sewer gas in your home, ventilate the area and call a professional to locate, assess, and fix the problem, as it will not go away on its own.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.
