What Happens When You Do Not Pump Your Septic Tank?

If you don’t pump your septic tank regularly, solid waste builds up inside the tank. Over time, this can cause blockages, sewage backups, foul odors, and even damage to your drain field. Neglecting septic pumping can lead to costly repairs or a full system replacement. Most homeowners should pump their septic tank every 3–5 years, depending on household size and usage.
