"I contacted Andy from Area Septic Installation Inc. because I was selling my house and the septic system did not pass the inspection. I normally contact 3 providers to get the best price. Andy was the only one to call me back and to come out to the house. Andy was very friendly, and provided me with great information and no hassle/pressure bid. Because I was selling the house there was a tight deadline on getting the work done. The time of year that I needed the work done is extremely busy and the weather did not cooperate. Andy also took time to explain to me some of the deceptive practices in this line of work and cautioned me not to become victimized. I thought that in and of itself was remarkable that he gave me this information so I would not become victimized. Andy showed up on the day he said he would be there, and got to work immediately. Andy knew that I was on a tight deadline to close and he worked long and extra hours to get the job done. His price was very reasonable for the work that needed to be done. Andy did everything to make this as easy as possible, and did a great job. When the work was completed Andy wanted me to come check the work to make sure it was up to my satisfaction before he left. Andy had the yard looking great back to its natural look. If you are in need of septic work I would strongly suggest calling Area Septic Installation Inc. for the work. Hard workers, Honest contractor, and fair pricing what more could you want. Jim Z."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

You can find your septic tank using a few different methods. For one, you can check your property records at your local municipal office. You can also inspect your yard looking for a depression, a septic tank lid, or lush septic-area vegetation which would indicate a leach field. You can also follow your pipes from the home to the yard. If you can't find your septic tank on your own, a local septic pro can help.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.
