"We could not be happier with the service we were provided with and their pricing was VERY affordable. Finding an honest, family owned business is hard these days, well you have found it. Not only was the owner very, very friendly and informative over the phone, he came to our house during the service call and was one of the NICEST people we have ever met. His workers arrived at the stroke of 7:30am, the exact time we were told, they were super nice, knowledgeable, clean and even texted us beforehand to let us know they were on their way. WE HIGHLY, HIGHLY RECOMMEND THIS COMPANY. They really gave us a great price for emptying our two cesspools and the service was done in a timely manner and our lawn was not left a mess. TWO BIG THUMBS UP! We would definitely use them again in a minute."

"The owner gave me a price over the phone. The technician that came out charged me less. In my experience, in this industry, it's not often that a company is this honest. Usually, you get a price, and suddenly there are a bunch of "absolutely necessary" add-ons. They are the only septic/sewer company I will ever call again!"

"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."

"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 🙏🏽."

"Called this afternoon, got called back within 10 minutes, appointment this evening. Jason literally pulled up to my house seconds after I got home from work. Total elapsed time from arrival to my heat being on was less than 30 minutes. There was a clogged line in the heater, which Jason just cleared out and got it working. No trying to get me to purchase stuff I don't need, no upcharge for same day. Polite, cleaned up after himself, nice to my dog. Awesome. Highly recommended."

Sewer Cleaning FAQs, answered by experts

Yes, rats can come up through drains. They can crawl through basement floor drains, lateral house drains, and roof drains. Installing rat blockers in your drains is the best way to repel rats and prevent them from entering your pipes. These are one-way valves that allow water and waste to flow out but keep rats from getting in.

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.

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

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.

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.
