"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!"

"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 found Cesspool Kings and John answered my call to fix/replace a kitchen faucet. He was able to accommodate us on the same day. After sending him pictures of our problem he immediately responded and went out to buy a new faucet and replace it with no problem. He was very nice and knowledgeable about the work. Pricing was very reasonable and would highly recommend Cesspool Kings. We will definitely use their services again for all our plumbing and cesspool needs. Five Stars ⭐️⭐️⭐️⭐️⭐️"

"Our shower suddenly stopped draining. We contacted ANGI and were given this company’s information. They called and said they could come right out. The repair tech was there soon and fixed the issue quickly and completely. He even cleaned the area when he finished. We were very happy with this company and will probably call them again for future repairs."

French Drains FAQs, answered by experts

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

If your kitchen is flooding, first turn off the water supply and electricity before entering the room. Next, focus on immediate flood control by cleaning up any standing water with a sump pump or wet-dry vacuum to prevent long-term water damage to your home. Open your windows and run any dehumidifiers you have handy. Finally, call a professional plumber to help find the source of the flood and repair it.

To unclog the drain pipe, remove the machine's drain hose from the pipe or sink drain, being careful to contain any water in it. Next, use a plunger for sink drains or a plumbing snake for a wall drain. Test the repair by pouring a small amount of water into the pipe before trying it with a laundry load.
