Service Overview
ATU Pump Repair With Clear Answers Before Work Begins
Your aerobic treatment unit (ATU) depends on a working pump to aerate, treat, and distribute wastewater properly. When that pump fails — or starts showing signs of trouble — your entire system can back up, trigger alarms, and put your property out of compliance. It's stressful, and it can escalate quickly. That's where Lapin Services comes in. We diagnose ATU pump problems fast, repair or replace what's needed, and get your system back to working order — the right way, the first time.
With 65+ years of septic experience, a 4.9-star Google rating from over 1,000 Central Florida homeowners, and a licensed Master Septic Contractor on our team, we're the company your neighbors call when their ATU stops working. Whether your pump has seized, lost power, burned out, or simply worn down over time, we have the expertise and parts to fix it — and the honest communication to walk you through every step.
Problems We Solve
Common ATU Pump Repair Problems We Fix
You do not have to diagnose the problem yourself. These are common issues we help confirm, explain, and repair.
Burned-Out or Seized Pump Motor
Over time, ATU pump motors wear down from continuous cycling. A seized or burned-out motor is one of the most common ATU failures we see in Central Florida. The pump simply stops turning, aeration stops, and your system loses its ability to treat wastewater effectively. We inspect the motor, confirm the cause, and replace the unit with the correct pump for your system.
Clogged or Air-Locked Pump
Debris, grease buildup, or air locks can prevent your ATU pump from moving water even when the motor is intact. This often triggers a false "working" state where the pump runs but nothing moves. Left alone, it causes treatment failure and potential odors or overflow. A proper cleaning, inspection, and restart procedure resolves most clogs without a full replacement.
Alarm Triggered but Cause Unknown
ATU systems are designed to alert you when something is wrong — but the alarm doesn't tell you what. A triggered alarm could point to a pump failure, a float switch malfunction, high water levels, or an electrical issue. Our technicians trace the alarm to its source, so you get a real fix instead of just resetting a light that comes back on tomorrow.
Float Switch or Electrical Failure
The pump doesn't run on its own — it depends on float switches and electrical controls to know when to activate. A failed float switch can leave your pump off when it should be running, or running when it shouldn't. Wiring issues and control panel faults are also common culprits. We inspect the full electrical and control system, not just the pump itself.
Pump Running but Not Aerating Properly
Sometimes the pump runs fine mechanically but isn't delivering adequate aeration — often due to a cracked diffuser, a broken air line, or wear on internal components. Your system won't treat wastewater effectively, and the problem may not be obvious until an inspection. We test aeration output during every ATU pump service call to catch these issues early.
When to Call
Signs Your Septic System Needs Professional Attention
If you notice any of these signs, call Lapin. We will find the cause and explain what needs to happen next.
Your ATU Alarm Is Sounding
An active alarm is your system's way of telling you something is wrong. Don't silence it and hope it clears — that alarm exists to protect you. Call us to diagnose what's triggering it before a fixable pump issue becomes a costly system failure.
Foul Odors Near Your Septic Area
When an ATU pump stops aerating properly, untreated wastewater builds up and creates strong odors near your tank, drainfield, or spray heads. If you're noticing smells that weren't there before, a pump issue is a likely cause and should be inspected promptly.
Slow Drains or Backups Inside the Home
A pump failure can cause wastewater to back up through your entire system. If drains throughout your home are running slow or backing up — especially paired with an odor — your ATU may not be processing and dispersing wastewater the way it should.
Spray Heads That Are No Longer Working
ATU systems with spray irrigation rely on the pump to distribute treated effluent. If your spray heads have stopped operating, lost pressure, or are running dry, the pump system may have failed or lost prime. This is a sign that needs immediate attention to stay compliant with county requirements.
You Haven't Had Your ATU Serviced in Over a Year
ATU pumps work hard — they run in cycles every day. Regular inspections catch worn components before they fail completely. If it's been more than 12 months since your last ATU service, a maintenance check is the most cost-effective way to avoid an unexpected breakdown.

FAQs
ATU Pump Repair FAQs
How do I know if my ATU pump has failed?
The most common signs are a sounding alarm, foul odors near your septic system, slow or backed-up drains inside the house, or spray heads that have stopped working. If you’re seeing any of these, don’t wait — call Lapin Services at (407) 326-3367. ATU pump problems tend to get worse and more expensive the longer they go unaddressed.
Can my ATU pump be repaired, or does it always need to be replaced?
It depends on the failure. Some issues — like a clogged pump, a failed float switch, or a wiring problem — can be repaired without replacing the pump itself. If the motor has burned out or the pump has seized beyond repair, a replacement is the right call. We’ll diagnose the actual cause and give you an honest recommendation before any work begins.
How long does an ATU pump repair take?
Most ATU pump repairs are completed in a single visit, typically within a few hours. The timeline depends on the complexity of the issue and whether replacement parts are needed on-site. Our technicians carry common pump models and components, which helps us resolve most repairs the same day we diagnose them.
My ATU alarm went off but then stopped. Do I still need to call?
Yes. An alarm that stops on its own doesn’t mean the problem is resolved — it often means water levels dropped temporarily or a float reset by chance. The underlying cause is still there. Ignoring a cleared alarm is one of the most common reasons homeowners end up with bigger, costlier failures down the road. It’s worth a call to get it properly checked out.
Is ATU pump repair something I can do myself?
We strongly advise against it. ATU systems involve electrical components, wastewater, and county compliance requirements. Incorrect repairs can void warranties, cause additional damage, or leave your system out of compliance — which can result in fines. Licensed septic contractors like Lapin Services have the certifications and tools to do this safely and correctly.
How often should my ATU pump be inspected?
Most ATU systems should be inspected at least once a year — and in Florida, many counties require routine ATU maintenance contracts. Annual inspections catch worn pump components, clogged diffusers, and electrical issues before they cause a full failure. If you’re not sure about your current maintenance schedule, we’re happy to review your system and set you up on a plan.
Do you service all ATU brands and models?
Yes. Lapin Services services all major ATU brands and models common in Central Florida, including Norweco, Jet, Advantex, BioMicrobics, and others. Our technicians are experienced across system types and carry a wide range of replacement pumps and components to handle most repairs in a single visit.
What areas do you serve for ATU pump repair?
We serve all of Central Florida, including Orlando, Orange County, Seminole County, Osceola County, Lake County, and surrounding areas. If you’re unsure whether we cover your location, give us a call at (407) 326-3367 and we’ll confirm availability for your address.
