Problems We Solve
Common ATU Float Switch Repair Problems We Fix
Here are the issues our team commonly finds and resolves during atu float switch repair calls across Central Florida.
Float Switch Stuck in the On or Off Position
A float switch that gets stuck — whether held up by debris or tangled in position — causes your ATU pump to run continuously or not at all. Either situation stresses your system and can lead to premature pump failure or effluent backup. We clear obstructions and replace worn switches that can no longer move freely.
Corroded or Damaged Float Switch Wiring
Float switches live in a wet, corrosive environment. Over time, the wiring connecting the switch to your control panel can degrade, short out, or break entirely — triggering false alarms or causing the pump to lose signal. Our technicians inspect the full wiring path and repair or replace damaged connections to restore reliable communication between your float and your system.
Incorrect Float Switch Calibration
A float switch set to the wrong depth activates at the wrong water level — either allowing wastewater to build up too high before pumping or cycling the pump too frequently. This shortens component life and reduces treatment efficiency. We calibrate your float to manufacturer specs so your ATU pumps at exactly the right intervals.
Float Switch Triggering the ATU Alarm
If your ATU alarm light or buzzer has activated, a malfunctioning float switch is one of the most common culprits. High-water floats are designed to alert you when levels exceed safe limits — but a faulty switch can trigger that alarm even when levels are normal. We diagnose whether the alarm reflects a true high-water condition or a failed switch, and we fix the root cause.
Float Switch Failure After a Storm or Flood Event
Heavy rainfall and flooding in Central Florida can submerge ATU components beyond their operating range, overwhelming float switches or forcing debris into the tank that jams the mechanism. After a major rain event, it's worth having your float switch inspected — problems that develop slowly after flooding often cause bigger failures down the road.
When to Call
Signs Your Septic System Needs Professional Attention
If you notice any of these warning signs, schedule atu float switch repair before the problem becomes more disruptive or expensive.
Your ATU Alarm Is Going Off
An active alarm on your aerobic treatment unit is one of the clearest indicators that something is wrong — and a failed or stuck float switch is a frequent cause. Don't silence the alarm and wait. Call Lapin Services so we can determine whether you have a genuine high-water situation or a faulty switch triggering a false alert.
Your ATU Pump Runs Constantly or Not at All
Normal ATU pumps cycle on and off based on water levels detected by the float switch. If your pump never seems to shut off, or if it hasn't kicked on in a long time, the float switch may be sending the wrong signal — or no signal at all. Both patterns put unnecessary wear on your system and compromise treatment performance.
You Notice Odors Near Your Drainfield or Tank Area
Foul smells around your yard, drainfield, or septic tank area can indicate that wastewater isn't being pumped or treated properly — a situation a malfunctioning float switch can cause. If you're catching odors outside your home and your ATU hasn't been serviced recently, it's time to have a technician take a look.
Your ATU Is Overdue for Inspection
Florida requires regular ATU inspections, and float switches are a key component checked during those visits. If your system hasn't been inspected in over a year — or if you're preparing for a property sale or transfer — having your float switch evaluated now can prevent costly surprises and keep you on the right side of county compliance requirements.
You See Standing Water or Wet Spots Near Your Septic Area
Unusually wet ground above your drainfield or near your tank, especially when it hasn't rained recently, can be a sign that your ATU isn't pumping correctly. A float switch that fails to trigger the pump allows liquid levels to rise and eventually overflow into areas they shouldn't reach. Get it checked before the problem spreads.
Our Process
What to Expect From Your ATU Float Switch 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 Us — Day or Night
Reach our team at (407) 326-3367 any time, 24 hours a day. Describe what you're seeing — an active alarm, a pump that won't cycle, unusual odors — and we'll dispatch a licensed technician to your Central Florida home or property as quickly as possible.
Step 2
On-Site ATU Diagnosis
Our technician inspects your aerobic treatment unit from top to bottom — checking the float switch position, wiring, connections, and control panel signals. We don't guess. We confirm exactly what's wrong before recommending any repair so you have a clear picture of the issue and what it will take to fix it.
Step 3
Upfront Repair Assessment
Once we've identified the problem, we walk you through our findings in plain language and provide an honest, transparent cost estimate before any work begins. No surprises on your invoice. If a simple float switch replacement is all that's needed, we'll tell you. If we find a deeper issue, we'll explain that too.
Step 4
Float Switch Repair or Replacement
We repair or replace your ATU float switch using quality components suited to your system's make and model. Our technicians also inspect adjacent components — wiring, control panel connections, and pump function — to confirm the repair resolves the issue completely and your ATU is operating as it should.
Step 5
System Test and Documentation
Before we leave, we run a full operational check to verify the float switch is cycling correctly at the right water levels, the alarm has cleared, and the pump is responding properly. We provide documentation of the work completed — useful for your records, county inspections, and any future service visits.

FAQs
ATU Float Switch Repair FAQs
What does a float switch do in an ATU?
A float switch monitors the water level inside your aerobic treatment unit. When the liquid rises to a set point, the float triggers the pump to activate and move treated effluent to the drainfield or spray heads. It also controls the high-water alarm — alerting you if levels climb beyond a safe threshold. Without a properly functioning float switch, your ATU can’t regulate pumping cycles, which puts the entire system at risk.
How do I know if my ATU float switch is the cause of the alarm?
A high-water alarm can be triggered by a genuinely elevated water level in the tank — or by a float switch that’s stuck, miscalibrated, or sending a false signal. Without opening the tank and inspecting the switch directly, it’s difficult to tell from the outside. Our technicians diagnose the root cause on-site so you know exactly what you’re dealing with before any repair begins.
Can I reset my ATU alarm myself?
Most ATU control panels have a manual alarm silence or reset button, and pressing it may temporarily stop the noise. However, silencing the alarm doesn’t fix the underlying problem. If a float switch failure, high water level, or pump issue triggered the alarm in the first place, the condition will persist — and can worsen. We recommend calling for a professional inspection rather than relying on a reset alone.
How long does a float switch replacement take?
In most cases, replacing an ATU float switch is a straightforward repair that our technicians can complete during a single visit. The actual replacement typically takes under an hour, though the full appointment time includes diagnosis, inspection of surrounding components, and a post-repair system test to confirm everything is working correctly before we leave.
How much does ATU float switch repair cost in Orlando?
The cost depends on the type of float switch your system requires, the extent of any related wiring or component issues, and the condition of your ATU overall. We provide a transparent, upfront estimate after the on-site diagnosis — so you know exactly what you’ll pay before work begins. Call (407) 326-3367 to schedule an assessment.
Is float switch repair covered under any warranty?
Lapin Services stands behind our work. We offer warranties on labor and components for the repairs we perform — your technician will detail the specific warranty terms when reviewing your repair estimate. If a concern arises after we’ve completed the job, contact us and we’ll make it right.
Does Florida require ATU inspections, and does the float switch get checked?
Yes. Florida requires aerobic treatment units to be inspected on a regular schedule — typically every six months to annually depending on your county. During inspections, technicians check the float switch, alarm function, spray heads, pump operation, and overall treatment performance. Lapin Services handles ATU inspections and can ensure your system remains compliant with Orange, Osceola, Seminole, Lake, and surrounding county requirements.
Do you service all ATU brands in the Orlando area?
Yes. Our technicians work on aerobic treatment units from all major manufacturers commonly found in Central Florida, including Norweco, Jet, Bio-Microbics, Infiltrator, and others. If you’re unsure of your unit’s make or model, that’s fine — we’ll identify it on-site and source the correct replacement float switch for your specific system.
