Most residential septic tanks need pumping every 3-5 years, but Jefferson Park’s clay soil can change that timeline. Clay doesn’t drain as quickly as sandy soil, which means your system works harder and may fill up faster.
The real answer depends on your household size, water usage, and tank capacity. A family of four with a 1,000-gallon tank typically needs pumping every 3-4 years. But if you have a garbage disposal, do lots of laundry, or your tank is smaller, you might need service every 2-3 years.
Signs it’s time include slow drains throughout the house, sewage odors near the tank area, or wet spots in your drain field. Don’t wait for backups – they’re expensive and unsanitary to clean up.
