"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."

"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

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

Some of the most common plumbing problems in mobile homes are frozen pipes, leaking pipes, clogged drains, and low pressure. Since the pipes in a mobile home aren’t as insulated as those in a standard build, they’re more susceptible to fluctuating temperatures and damage. 

In most cases, drain cleaners will not clear a clogged sewer line, and they’re likely to damage your plumbing. Sewer lines are several inches wide, meaning any material that clogs it will need to be large. Drain cleaner can work on small clogs, but it usually won’t clear a larger one in a sewer main. Drain cleaners can also easily damage and corrode your plumbing with prolonged contact, and a clog will keep the cleaner in contact with the pipes for an extended period. Hire a professional sewer cleaner instead for a safe fix.

A sewer cleanout typically looks like a white or gray PVC pipe with a removable cap. It's often located either in your yard or basement, depending on your home's plumbing configuration. The cleanout pipe is designed to provide easy access to your sewer system for maintenance and inspections. It may be flush with the ground or slightly elevated, making it distinguishable from other pipes. When you remove the cap, you can access the sewer line directly or determine its direction, which can be helpful when you need to locate your sewer line from your house to the street.
