"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 questions, answered by experts

A submersible pump should be at least 10 feet from the bottom of the well to minimize the risk of the pump drawing debris into the well water. Submersible pumps work best for wells that are 25 feet deep or less. If you have a deeper well, choose a jet pump instead of a submersible model.

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.

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.

A properly installed and maintained septic drain field (also known as a leach field) can last up to 50 years, though the average is around 20 years. However, factors like poor soil conditions, heavy usage, or improper maintenance can significantly shorten its lifespan to 15-20 years.

To extend the life of your drain field:

  • Schedule Regular Inspections: Have the entire septic system, including the drain field, inspected every two to five years to catch problems early.

  • Protect the Area: Avoid driving heavy vehicles or placing heavy structures over the drain field. Plant only grass or other lightweight vegetation with shallow roots over the area.

  • Maintain the Septic Tank: Proper care of the septic tank, including regular pumping and avoiding harmful chemicals, prevents strain on the drain field.

Be aware of signs of failure, such as strange odors, standing water, or unusually lush grass over the field, which indicate your system may need professional attention.

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.
