"Thank goodness for Mastero Edgar, his family and Crew! It was a dark and stormy night in Feb 2021, icy yard and flooded basement. We had cleared our septic tank 3 months prior and the basement flooded with clean water! We had hired a plumbing company 2 nights in a row...no clear answers despite hours of work!! Then I reached Angie.. Mr. Edgars daughter , Mr. Edgar overheard me, and spoke to me at 8:45 pm... on a Saturday night !!!! He did not have to... but he did. He found the problem....the following day I watched the most synchronized orchestra by the team ! Still mesmerized by the way the work was carried out! I work in health care, I am a business woman and I love classical music! Let me tell you all, their work is innovative! My husband and I live in peace after those 3 agonizing days... knowing that there are angles out there and then there is Mastero Edgar, his family and crew! Clean, professional, affordable. Mr. Edgar, thanks again for the reminder to “go an extra mile” when I care for my clients! Regards, Grace Paul. Rockville, MD"

"We were in the process of selling our home and the septic inspection revlealed that our drainage field had failed. Legacy septic was very responsive to our closing/reloaction dates and had the drainage field replaced within 7 days of calling. Highly recommend."

"After bathroom remodel, it was determined the new tile was raised beyond the limit of the existing flange and the new toilet could not be installed as is. Called Heil plumbing and they sent Dave on short notice. Dave arrived on time, courteous, and knowledgeable. He quickly assessed the issue and provided an inexpensive solution that did not require cutting into drywall. Dave quickly made the repair and installed the toilet. I highly recommend Dave and will request his services for any future work."

"Definitive Plumbing did a great job Installing a tankless electric water heater in my house and it works beautifully! They were extremely responsive and came back to make an adjustment to ensure the water temperature and flow were maximized. They also removed the existing water heater, and although we had a miscommunication about how that would happen, they came back and did some additional work to rectify the issue—which is really the type of customer service you want from a vendor. Keon and DJ are very honorable and they want to make sure the customer is satisfied."

"I had Tri-County Pumps come and install my water treatment system that I bought. I also needed a new pressure tank for my system. They came and gave me a quote for the installation of the water treatment system (that I already owned) and for the new pressure tank. They came and gave a free estimate. Their prices were exactly what I was looking for in terms of cost. When they arrived to do the install, they were really professional and clean. They did the job quickly and wow did they do a great job. They kept it tight and compact and the location where they installed it was clean. I would highly recommend using this company."

Septic Tanks FAQs, answered by experts

Talking with a septic pro before planting trees near your tank is best to ensure the roots won’t interfere with your septic system. However, there is an easy way to figure out where to plant a tree—but you’ll need to know how tall it can get when it’s fully grown. For instance, if the tree can reach 50 feet, plant it at least 50 feet from your septic system.

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

If your septic tank is still within its expected lifespan and you need to relocate it on your property, it's possible to do so. However, because the task is so labor-intensive and costly, most homeowners simply choose to abandon the old tank if possible and install a new system in the new location. In either case, hiring a professional installation company will be necessary for the job.
