"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!"

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."

"Jason called immediately after I posted my request. He came to give an estimate to replace some baseboard, and I told him of issues with two of my toilets. He looked at them and fixed the problems right then! They were prompt to the appointment, neat, and professional. When I had an issue with the oil burner (due to draining of the system) he came back and fixed the problem. Definitely recommend!"

French Drains FAQs, answered by experts

No, it is not advisable to spray pesticides down the drain in your home. Most drinking water and wastewater treatment systems are not properly equipped to remove pesticides. Should pesticides infiltrate waterways, they can cause harm to plants, fish, or other living things. In most areas, pouring pesticides down the drain is illegal due to the potential harm it causes. 

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

The cost varies from $150 to $600, depending on the severity of the clog, pipe access, and required equipment.

Yes, you can use vinegar to unclog a dishwasher. To do so, combine 4 tablespoons of white vinegar with 4 tablespoons of baking soda and pour the mixture down your dishwasher’s drain. Let it sit for 15 minutes, then pour a cup of hot water down the drain to flush everything out. Finally, run a rinse cycle on your dishwasher to see if the clog is gone.
