"Chase gave us a good estimate on the tankless system and recommended a new, larger pressure tank, which we knew we needed. He provided information on the options and checked to make sure that our choices would maintain the proper value of our house. The team did a good job of installing the new equipment, keeping us informed through the process. It was reliable and painless. Of note: we sent requests to 3 plumbing companies through Home Advisor, and Benjamin Franklin was the only company to respond at all. The office contacted me the same day."

"Stephen handled the septic tank and leach field installation from start to finish. 1000 gallon tank and 4 50' leach lines. Very considerate and responsive. Explained the whole process. Closely worked with the Environmental Health inspectors. Worked me in earlier than scheduled and completed the project in one day. Would highly recommend Stephen for your septic project."

"Preston went out of his way to make sure our septic tank was properly inspected. With very little information from the home owners he went above and beyond to find the tank and properly inspect it! This is the second time we have hired him and both times he has been exemplary! The first time he saved us from purchasing a home with a disaster of a septic situation. I would highly recommend hiring him for your septic needs!"

Septic Tanks FAQs, answered by experts

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
