Signs Your Septic System Needs Repair
Don’t wait until you have a full backup. These are the warning signs that something is wrong and it’s time to call us:
- Sewage smell inside your home or in the yard
- Drains gurgling or draining slowly throughout the house
- Wet or soggy ground around your septic tank or drain field

- Toilets flushing slowly or backing up
- Unusually green or lush grass over the drain field area
- System has not been inspected in over 4 months (required by TCEQ for aerobic systems)
What We Repair
Aerator & Air Pump Repair
The aerator is the heart of an aerobic system. If it fails, your system stops treating waste properly. We replace aerators, diaphragms, and air pumps quickly to keep your system TCEQ-compliant.
Pump Repair & Replacement
A failing pump means waste isn’t moving where it needs to go. We diagnose submersible pump failures and replace them with the correct unit for your system.
Spray Heads & Drip Lines
Clogged or broken spray heads cause uneven distribution and can lead to system failure. We clean, adjust, and replace spray heads and drip irrigation lines.
Electrical & Control Panel Repairs
Faulty wiring, bad floats, or a malfunctioning control panel can trigger alarms and shut your system down. We troubleshoot and repair all electrical components
Float Replacement
Floats control water levels inside your tanks. A stuck or failed float can cause overflows or alarms. We test and replace floats on all system types.
Drain Field Repair
A failing drain field is one of the most serious septic problems. We assess your drain field, identify the cause of failure, and provide honest options, repair or replacement, with no pressure. If your system needs a full rebuild, our septic installation team can handle that too.

Frequently Asked Questions
How do I know if my septic system needs repair?
