"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!"

"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."

"People listen to me. If you want great service at affordable prices call this company. Carl who owns this business is absolutely phenomenal. Carl cares about his customers. There are plumbing services that are just looking to make as much money off the customer as possible. Often not providing the right type of service. NOT this business!! Carl is more concerned about the customer being satisfied while providing accurate and great service. Carl came while it was pouring down raining. He had to work inside and at times go outside in the rain. He unclogged multiple drains while also clearing the pipes leading to the sewer. Carl even installed my washer and dryer. He also cleaned all my gutters. Absolutely Phenomenal!!! And all this at an affordable price. People do yourself a favor and call Affordable Sewer if you ever need plumbing service. I guarantee you will not be disappointed."

"Just had this done in Feb 2019. Turns out vendor who I used then didn't clean any of the solid waste from cesspool . He only drained fluids. Had same overflow problem again this weekend and was pretty mad. Call Mid Suffolk and was greeted very professionally and kindly on phone by Christine on Saturday night Sept 14th 2019. Was told her husband Bob would show up Sunday morning. He did at 11am and provided much need excellent service and advice. Completely serviced both pools for a reasonable price. Was neat and would call again without any second thought."

Sewer Cleaning FAQs, answered by experts

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

Toilet paper is the only material that you should flush down toilets. Other items like wipes, paper towels, feminine hygiene products, dental floss, and medications should be disposed of in the trash. Flushing these items can lead to plumbing issues and damage to sewage systems. Grease and cooking oils should also be avoided as they can solidify in pipes, causing blockages. Proper disposal helps prevent clogs and ensures the efficient operation of wastewater treatment systems while protecting the environment.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.
