Buyer’s Guide: Why Is My Aerobic Septic Alarm Going Off?
- High Water Level: Most alarms mean the water in your spray tank is too high, usually because the pump isn’t working or can’t keep up.
- Low Air Pressure: Aerobic systems need air for proper treatment. If your air pump fails or a filter clogs, an alarm may sound.
- Float Switch Stuck: If the float that detects water level is jammed or broken, it can send a false alarm.
- Power Issues: Power loss, tripped breakers, or GFCI outlets can stop pumps and air compressors, triggering an alert.
- Pump Failure: Over time, septic pumps can wear out, overheat, or get blocked, causing backups and alarms.
- Sprinkler Head or Line Blockage: If your spray system can’t disperse water, the tank fills up and alarms sound.
The alarm is there to protect your property—don’t ignore it. Start troubleshooting right away.
