Skipping ATU maintenance Southwest Florida isn't just a risk to your system — it's a legal and financial liability. Here's what can go wrong:
Operating an ATU without a valid maintenance agreement or current annual inspection can result in citations and fines from your county health department.
Without regular aerator and pump checks, small mechanical issues escalate into full system failures — often at the worst possible time.
A neglected filter sends untreated sewage toward your drain field, causing premature drain field failure and costly replacement.
Improperly treated effluent reaching groundwater is an environmental violation under Florida onsite sewage regulations.
Most ATU manufacturers require documented aerobic treatment unit maintenance by a licensed contractor to keep equipment warranties valid.
