"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 FAQs, answered by experts

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.

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

The average lifespan of a deep well pump is between 15 and 25 years, after which you’ll have to replace it. Several factors can affect the lifespan of a well pump, such as the quality of the unit. Proper maintenance and repair can also help extend your well pump’s lifespan as well as keep adequate water flow and pressure throughout your home.

A well pressure tank is located between the well and the well pump, and it stores your water under pressure so that the well pump can eventually do its job. The well pump is activated whenever you turn a faucet on—it pulls the water from the tank into your home. Both are vital parts of a complete well water system.

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.
