What are you seeing right now?
Common Septic System Failures
Overloaded fields, failed pumps, stuck floats, cracked tanks, damaged baffles, clogged lines and electrical faults cause most failures. Flushing wipes and grease, heavy laundry loads and skipped maintenance make them worse.
Conventional and Aerobic Systems
Conventional systems rely on gravity and soil. Aerobic systems add air, a pump and a spray or drip field, so they have more parts that can fail and need regular service. We tell you which type you have and what it needs.
Tank, Pump and Alarm Repairs
Typical repairs include float switches, control panels, air pumps, sprinkler heads, baffles, lids and risers. Many alarms are fixed without major work.
- Alarm and panel diagnosis
- Float and pump replacement
- Baffle and riser repair
- Lid and access repair
Drainfield Issues
Drainfield problems range from clogged distribution to total failure. Early action can save the field, while late action may require replacement. We explain what we see and what each option means.
Diagnosis and Qualified Repairs
Some repairs require authorized onsite sewage contractors and local approval. We separate plumbing work from regulated septic work and tell you before you commit.
Please don’t DIY this
- Do not ignore an alarm: silencing it does not fix the cause.
- Do not open or enter the tank: toxic gas is deadly.
- Do not add additives as a repair: they do not fix mechanical failures.
- Do not drive or build over the drainfield.
