"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!"

"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."

"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

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

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.

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.

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.
