Septic system repairs FAQs

A septic tank lasts 20 to 30 years and can extend its life up to 40 years with disciplined maintenance. Regular pumping, annual inspections, and careful use of the system ensure long-lasting performance. Proper care—including flushing only approved materials and scheduling professional cleanings—protects your septic system and maximizes its lifespan.

Leach field failure can often occur due to a lack of proper maintenance, hydraulic overload, or environmental factors. When too much water enters the septic system—like running multiple large laundry loads back-to-back—it can overwhelm the leach field. Regular professional inspections, ongoing maintenance, and spacing out high-water-use activities help prevent failure.

A septic tank shows repair needs when noticeable symptoms arise around your home. Noticeable signs include strong sewage odors at fixtures, recurring pipe blockages, pooling water or damp patches near the leach field, and areas of unusually bright green or spongy grass. These indicators confirm that deteriorating components or clogs exist. Monitoring such signs and scheduling timely professional inspections prevents further costly damage.

Adhering to a strict, scheduled maintenance plan prevents septic system repairs. An annual inspection and a pump-out every three to five years safeguard your system’s performance. Additionally, only flushing waste and toilet paper, installing drain filters, keeping nonapproved items out of the system, and avoiding excessive water use help maintain your septic system’s health and efficiency.
