What is Septic Tank Maintenance?

Septic tank maintenance encompasses regular checks, minor adjustments, component inspections, and preventive care tasks that help your septic system function efficiently. These tasks go beyond occasional pumping, giving you peace of mind that small issues are caught early and your system is running optimally.

Our maintenance services typically include:

  • Checking liquid levels and scum/sludge layers
  • Inspecting inlet and outlet baffles or tees
  • Verifying the drain-field / soil-absorption area is functioning
  • Testing for leaks, cracks, or defects in the tank shell
  • Assessing compaction or soil settlement around the drain field
  • Checking effluent filters (if installed) and cleaning/replacing them
  • Verifying pump operation (for effluent or dosing pumps)
  • Reviewing usage patterns (water volume, household changes)
  • Advising on safe practices to minimize strain on the system

By taking these steps, we help you avoid surprises like backups, soggy drain fields, or costly repairs down the road.
