"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."

"As a landlord I have had my fair share of plumbing issues.  I am particularly pleased with the service I receive from John owner of Knock You Plumb Out Plumbing.  John has replaced sewer lines for me along with other plumbing problems.  I have even referred John to friends, something I normally am hesitant to do because I don?t want to be involved if there are problems with the quality of the work.  But with Knock You Plumb Out Plumbing I am confident of quality work and service.  I highly recommend John.

"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

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too. 

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.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
