"Andrew did a great job fixed my upstairs toilet, had other plumbers try to figure out why the toilet wouldn't drain, Andrew used a camera in the main drain and found the problem. Awesome job, we are all set with the toilet and he checked the whole house for any other issues. We will use Andrew in the future, we highly recommend his services."

"By Andrew v. Engineer Dave Schofield of Capstone displayed professionalism by turning a flawed design for our Sudbury septic system into one highly adaptive and functional. He was purposeful about doing the right thing even when not winning installation contract, execution of which he in in fact supervised. In a business which includes its share of uneven performers, Schofield’s competence is a stand-out."

"Hayden first came because my septic overflowed a little--he found the blockage, fixed it, took a video of it so I could see it, and charged me very reasonably--on the weekend! Then he came back, did my Title V inspection and pumped me out. Again very prompt, thorough, meticulous. I highly recommend him. Easy to work with, reliable, *very* responsive."

"Sorry, looks like this review got stuck in draft mode for quite a while. But the good thing about that is everyone gets to read a review with an update 1.5 years later on the quality of the work completed! In late 2020 I had recently moved into my new home and the gas water heater wasn't working properly. It was leaky and at least needed the pressure relief valve replaced, but the tank was well past it's expected lifetime. The techs were very helpful, kind and knowledgeable. The valve replacement wasn't going to work because repairing the tank could damage it further, so the tank was replaced instead. The price was very reasonable and installation was done really well. They did a great job with cleanup too! One and a half years later and the tank has had zero issues! I would definitely recommend them for heavy jobs like this or more simple ones around the house. Thank you very much!"

Septic Tanks FAQs, answered by experts

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

With regular servicing and general upkeep, both a well pump and pressure tank can last for years. The average lifespan of a well pump is around eight to 15 years. A well pressure tank can last from seven to 10 years. How long a well pump and pressure tank lasts also depends on a variety of factors such as type, size, material, and brand.

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house’s wastewater—from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

Neither system is necessarily better or worse than the other, but one of the two might be better for your needs. For example, anaerobic systems are less expensive than aerobic ones and don’t use power to run. On the other hand, aerobic septic systems don’t take up as much space and are typically more efficient than their anaerobic counterparts.
