"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks questions, answered by experts

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.

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.

A shallow-well pump can pull water up to 25 feet deep. A deep-well pump can pull water up to 90 feet deep. A deep-well submersible pump can pull water up to 300 feet deep. Make sure to consult a pro to find out how deep your well is and get the right pump for your needs.

Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area’s reservoir and create aquifers, which then help to replenish your well.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.
