"Had the service line from our house to the septic (under the driveway) replaced as it had pulled away from the tank (which we later found was due to the original installer not doing it right). They removed the concrete, replaced the service line and replaced the concrete after. They came out quick for a quote, used a camera to inspect the line (which was nearly half of the cost of all other quotes to run a camera) and found the damaged pipe. Was put on their schedule quick (luckily they had an opening so soon) and they performed quality work. Communication was great from start to end. I can't say enough good things about this company. A+ Service"

Septic Tanks FAQs, answered by experts

Septic tank locations are sometimes public record, although it depends on local laws and the property age. Older properties may not have the septic tank information on public record. To check, you can talk to local permitting agencies, such as your local health department, the local environmental department, or the county clerk.

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.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.
