Hearing that loud septic alarm? Don’t panic — it doesn’t always mean disaster. In this guide, Fresh N Clean Septic walks you through the five most common septic alarms, what each one means, and the first steps you should take before calling for service.

We’ll explain:

  • High-Level Alarm — when your tank or pump chamber is over capacity
  • Low-Level Alarm — why your tank might be running too low
  • Compressor / Aerator Alarm — aeration issues in alternative septic systems
  • UV Light System Alarm — how to protect your wastewater treatment process
  • Effluent Filter Alarm — when solids are blocking your system’s outflow

💡 Pro Tip: Always silence the audible alarm first using the button or toggle switch — the light will stay on until the issue is resolved.
