Skipping regular pumping leads to sludge buildup that eventually clogs your drain field, the most expensive component of your septic system to repair or replace. Drain field replacement can cost $10,000-$20,000 or more, compared to $300-$600 for regular pumping.
An overloaded system will eventually back up into your home, creating health hazards and property damage. Sewage backup cleanup and restoration costs often exceed $10,000, not including the disruption to your daily life.
You’ll also face potential environmental violations and health department issues if your system fails and contaminates groundwater or neighboring properties. Regular maintenance prevents these expensive, stressful situations entirely.
