Problems We Solve
Common ATU Service Problems We Fix
Here are the issues our team commonly finds and resolves during atu service calls across Central Florida.
ATU Alarm Going Off
A flashing light or audible alarm on your ATU panel signals a system fault — often a failed pump, air compressor issue, or high water level. It needs attention quickly to avoid backups and potential code violations.
Spray Heads Not Working Properly
Clogged, broken, or misdirected spray heads can cause effluent to pool in the wrong areas, creating odors, wet spots, and potential health hazards on your property.
Air Compressor or Aerator Failure
The aerator is the heart of your ATU — it keeps the treatment process working. When it fails, the system stops treating wastewater effectively and can quickly fall out of compliance.
Missed Maintenance Contract Inspections
Florida requires ATU owners to maintain an active service contract with a licensed provider. Lapsed or missed inspections can result in county notices, fines, and system problems that went undetected.
Foul Odors or Wet Areas Near the System
Sewage smells or soggy ground near your ATU or spray field are warning signs that something isn't working correctly — from a clogged filter to a failing drainfield component.
When to Call
Signs Your Septic System Needs Professional Attention
If you notice any of these warning signs, schedule atu service before the problem becomes more disruptive or expensive.
Your ATU Alarm Panel Is Flashing or Beeping
Any alarm indicator — light, sound, or both — means the system has detected a fault. Don't silence it and wait. Call a licensed technician to diagnose the issue before it worsens.
You Haven't Had a Service Visit in Over a Year
ATUs require regular inspections under Florida law — typically every four months. If your last service visit was more than a year ago, your system and your compliance are both at risk.
Spray Heads Are Clogged, Missing, or Misdirected
Walk your property and inspect the spray heads. Blockages, broken heads, or heads spraying toward structures, water features, or property lines signal a problem that needs prompt correction.
You Notice Sewage Smells Indoors or Outside
A properly functioning ATU should produce little to no odor. Persistent sewage smells — anywhere on or near your property — indicate the treatment process isn't working as it should.
Your Service Contract Has Lapsed or Is Up for Renewal
Florida mandates an active service contract for all ATU owners. If yours has expired or you're unsure of its status, it's time to call. Lapin handles contract setup, maintenance visits, and county reporting.

FAQs
ATU Service FAQs
What is an ATU (aerobic treatment unit)?
An aerobic treatment unit (ATU) is an advanced type of septic system that uses oxygen and bacteria to treat wastewater to a higher standard than conventional septic tanks. Because they treat effluent more thoroughly, ATUs can be used on smaller lots or in areas where a standard septic system isn’t permitted. They require regular maintenance and an active service contract under Florida state law.
How often does my ATU need to be serviced?
Florida requires ATU owners to have an active maintenance contract with a licensed service provider. Most contracts include inspections every four months — three visits per year. During each visit, a technician checks the system components, refills chlorine tablets, inspects spray heads, reviews the control panel, and submits a report to the county. Annual pump-outs may also be required depending on your system and usage.
What happens if my ATU alarm goes off?
Don’t ignore it. An ATU alarm signals that something in the system has triggered a fault — this could be a high water level, a failed pump, a malfunctioning aerator, or a float switch issue. Call Lapin Services right away at (407) 326-3367. We’re available 24/7 and can dispatch a technician to diagnose and resolve the problem before it leads to a backup or compliance issue.
Do I need a maintenance contract for my ATU in Florida?
Yes. Florida state law requires all ATU owners to maintain an active service contract with a licensed septic contractor. The contract ensures your system is regularly inspected, serviced, and documented. Operating without a valid contract can result in county notices and fines. Lapin Services offers maintenance contracts that cover all required visits, county reporting, and documentation.
How do I know if my ATU spray heads are working correctly?
Walk your yard when the spray cycle is active and observe each head. Signs of a problem include heads that don’t pop up, spray with low pressure, are clogged with debris, spin incorrectly, or are aimed toward structures, driveways, water features, or neighboring property. If you notice any of these issues, call Lapin Services — misdirected or non-functioning spray heads can create health hazards and code violations.
Can Lapin Services handle county compliance and reporting for my ATU?
Absolutely. We handle all required documentation and submit inspection reports to the county on your behalf after each service visit. If your system has received a non-compliance notice, we can assess the issues, perform necessary repairs, and represent you through the resolution process. Compliance paperwork is included as part of our ATU service contracts.
My ATU is old — should I repair it or replace it?
That depends on the system’s age, condition, and what’s failing. Minor component repairs — pumps, aerators, spray heads — are often cost-effective even on older systems. If major structural components are failing or the system has a history of repeated problems, a full replacement may be the smarter long-term investment. Our technicians will give you an honest assessment so you can make the right decision for your home and budget.
How much does ATU service cost in Orlando?
ATU service costs vary based on what the system needs — a routine maintenance visit under a service contract is typically straightforward and predictable, while repairs depend on which components need attention. Lapin Services provides transparent pricing before any work begins. Call us at (407) 326-3367 for a quote, or schedule a visit and we’ll give you a full assessment with no obligation.
