Comprehensive Septic Repair Services

Whether you have a standard gravity-flow tank or a complex commercial aerobic setup, we have the parts, heavy equipment, and expertise to handle the job.

Aerator Repair & Replacement

If your Aerobic Treatment Unit (ATU) has a foul odor or the system alarm is going off, your aerator may have failed. The aerator pumps vital oxygen into the tank, allowing bacteria to break down waste quickly. We diagnose motor failures and install complete new aerator units to restore proper operation and keep your system working efficiently.

Control Panel Troubleshooting

The control panel is the brain of your advanced wastewater treatment system, managing pump cycles and alarms. If your system is tripping breakers, failing to pump, or constantly alarming, we can help. We repair and replace faulty wiring, broken timers, and bad switches in your control box to ensure your system operates on its correct schedule.

Spray Pump Repair

For ATUs that utilize spray irrigation, a broken pump means treated wastewater has nowhere to go—eventually leading to a backup. We repair and replace spray pumps, troubleshoot bad float switches, and fix clogged or broken sprinkler heads to keep your dispersal field operating safely and efficiently.
