"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!"

"We called Drain RX, on a Sunday, after noticing our basement was flooded and seemed to be coming from the toilet bowl (thank you toddlers lol). Victor called us back, came soon after, and diagnosed the problem. He had us fixed up and back on track in no time!! Super professional and we can not thank him enough!!"

"These people responded almost immediately to my request to clear a drain blockage. When the drain clogged again two days later, they came back immediately and snaked another part of the system successfully curing the problem. The revisit and work was free of charge. They even apologized for not permanently clearing the drain the first time. They were extremely nice and courteous and I would recommend them highly for any plumbing or sewage problem."

"Mario of Mario’s Faucet and Toilet Repairs in Bayshore NY was courteous and efficient. He cleared the clogged pipe and got the plumbing back in working order. He’s been doing this for 10 years so he’s very experienced. I think the price was very fair for the work done. I would highly recommend him for plumbing and drain issues. Thank you Mario!"

"I had an issue with a clogged drain that was causing a blockage and preventing the water from draining properly. The service was excellent from start to finish! Joe was very professional, arrived on time, and quickly identified and resolved the problem. Joe made sure everything was flowing properly before finishing the job. I truly appreciate his fast response, great customer service, and quality work. I highly recommend them to anyone experiencing drain clogs or blockages. Thank you for the outstanding service!"

Customers say: Terrific value

"Jack is a straight shooter and goes over the problems he sees and only positive solutions. Jack is personable and tried to save you money versus over sell unnecessary improvements. We need our foundation patched for leaks and his crew went over and beyond the work we thought we needed. Waterproofed our outside issues and then waterproofed the inside with paint. They cleaned up our crawl spaces as well as under the basement stairs. Jack even threw in a fire extinguisher and 2 water detectors. Great man, proud of what he does and loves to please his customers. HIghly recommend. Oh, his crew keep everything clean and when they left you would never have known they dug into our driveway and backyard to install leader drains from our gutters."

French Drains FAQs, answered by experts

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

There are several signs that can indicate your leach lines are broken, failing, or in need of repair, including puddles of water or a marshy consistency to the ground above or around the pipes, slow drainage or plumbing backups inside your home, and noticeable odors or gurgling sounds coming from your leach field. Keeping your septic system properly maintained, including having your septic tank pumped at regular intervals, can help ensure your leach lines stay in good working order for a long time.

Clogs in a sprinkler valve can be caused by various factors, including debris in the water supply, sediment buildup inside the valve, or damage to the diaphragm. Debris and sediment can accumulate over time, obstructing the valve's passages and impeding water flow. Damaged diaphragms may develop tears or holes, leading to blockages and affecting the valve's ability to open or close properly. Regular maintenance and cleaning can help prevent and address these issues, ensuring your sprinkler valve operates smoothly.

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.

If you drop jewelry down your sink, it can cause a clog, especially if it accumulates other debris on its way down. However, that is the least of your worries if you drop your favorite jewelry down your drain. If your gold band goes tumbling down the sink drain, don’t panic—refrain from running more water down the sink, and follow the steps above.
