Service Overview
ATU Pump Repair Backed by 65+ Years of Local Experience
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
Here are the issues our team commonly finds and resolves during atu pump repair calls across Central Florida.
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 warning signs, schedule atu pump repair before the problem becomes more disruptive or expensive.
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.
Our Process
What to Expect From Your ATU Pump Repair Visit
Lapin keeps the process straightforward from the first call through final documentation, so you know what is happening at every step.
Step 1
Call or Schedule Online
Reach us at (407) 326-3367 or schedule online anytime — including nights and weekends. Tell us what you're experiencing (alarm, odor, backup, or no spraying) and we'll dispatch a technician to your Central Florida home as quickly as possible.
Step 2
On-Site Diagnosis
Our technician arrives, inspects your ATU system, and identifies the root cause of the pump failure. We check the pump motor, float switches, air lines, diffusers, electrical controls, and water levels — not just the obvious symptoms. No guessing, no unnecessary parts.
Step 3
Honest Assessment and Upfront Pricing
We walk you through exactly what we found and what it takes to fix it — in plain language, not technical jargon. You'll know the cost before any work begins. If a repair will do the job, we'll say so. If a replacement makes more sense long-term, we'll tell you why.
Step 4
Pump Repair or Replacement
With your approval, we complete the repair or install the correct replacement pump for your ATU system. We test the unit under operating conditions before we leave — aeration output, float response, and full system cycling — so you know it's working, not just assumed to be.
Step 5
Post-Service Documentation and Follow-Up
We provide documentation of the work completed, including any parts replaced and the condition of the broader system. If we spotted anything else during the visit that warrants attention, we'll let you know — proactively, not in the middle of a future emergency.

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.
