Service Overview
Low Pressure Dosing System With Clear Answers Before Work Begins
A low pressure dosing (LPD) system is one of the most effective septic solutions for Central Florida properties where conventional drainfields struggle with sandy soils, high water tables, or limited yard space. Instead of releasing wastewater all at once, an LPD system doses small, controlled amounts of effluent evenly across the drainfield — giving the soil time to treat it properly and extending the life of your system significantly. When your LPD system is working right, you won't even know it's there. When it isn't, Lapin Services is the team to call.
Lapin Services has been Central Florida's go-to septic expert since 1958. Our licensed master septic contractors understand the unique soil conditions, county regulations, and site challenges that come with Orlando-area properties. Whether you need a new LPD system installed, a failing pump replaced, or routine maintenance to keep things running, we handle it all — with the experience, honesty, and fast response your home deserves.
Problems We Solve
Common Low Pressure Dosing System Problems We Fix
You do not have to diagnose the problem yourself. These are common issues we help confirm, explain, and repair.
Pump Failure or Malfunction
The dosing pump is the heart of your LPD system — it delivers effluent in precise, timed doses to the drainfield. When the pump fails, effluent backs up in the dosing chamber and can quickly create a health hazard. Pump failures are one of the most common LPD service calls we respond to, and our team carries the parts and expertise to diagnose and resolve them fast.
Clogged or Saturated Drainfield Lines
Even with a dosing system managing distribution, drainfield lines can become clogged over time with biomat buildup or debris. When lines are blocked, effluent can't absorb properly, leading to wet spots, odors, or surface ponding in your yard. Left untreated, a saturated drainfield can fail entirely — a much costlier fix than early intervention.
Timer or Control Panel Problems
Your LPD system relies on a timed control panel to schedule dosing intervals throughout the day. If the timer malfunctions or the panel loses power, the system either stops dosing altogether or doses continuously — both of which stress the drainfield. We troubleshoot and repair control panels and timers to restore proper cycling and protect your drainfield's long-term health.
Float Switch Failure
Float switches monitor the liquid level in your dosing chamber and trigger the pump to activate at the right time. A stuck or failed float switch can cause the pump to run dry (burning it out) or allow the chamber to overflow. Float switch issues are often subtle until they cause bigger problems — regular inspections catch them before they escalate.
Uneven Dosing Across the Drainfield
LPD systems are designed to distribute effluent evenly through a network of small-diameter pipes. If a lateral line cracks, a nozzle clogs, or a fitting fails, some zones receive too much effluent while others receive none. This uneven distribution overloads part of the drainfield and underuses the rest, shortening the life of the entire system.
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.
Alarm Light or Buzzer Is Activated
Most LPD systems include a control panel with an alarm that triggers when the dosing chamber fills too high or the pump fails to activate. If your alarm light is on or you hear the alert tone, don't ignore it — call us right away. An active alarm almost always means something in the system needs immediate attention.
Wet or Soggy Spots in Your Yard
Pooling water or consistently soggy areas above your drainfield are a sign that effluent isn't being absorbed properly. This could point to a drainfield overload, clogged laterals, or a pump dosing too frequently. Surface saturation can also create a health risk for your family and pets — don't wait to have it evaluated.
Slow Drains or Sewage Odors Indoors
When a low pressure dosing system backs up, the first signs are often inside the house — toilets that flush slowly, drains that gurgle, or the unmistakable smell of sewage near fixtures. These symptoms mean wastewater has nowhere to go and the system needs attention before you have a full backup on your hands.
It's Been More Than a Year Since Your Last Inspection
LPD systems have more mechanical components than conventional septic systems — the pump, floats, timer, and distribution network all need periodic inspection. Annual service visits catch small issues before they become expensive failures and keep your system operating within county compliance requirements.
Your System Is 10+ Years Old Without Service
Dosing pumps and floats have a finite lifespan. A system that's never been serviced — or hasn't been inspected in many years — is overdue for a professional evaluation. Proactive maintenance is far less expensive than an emergency repair or drainfield replacement, and it gives you peace of mind that the system is sound.

FAQs
Low Pressure Dosing System FAQs
What is a low pressure dosing septic system?
A low pressure dosing (LPD) system is a type of septic system that uses a pump to deliver small, timed doses of effluent to the drainfield through a network of small-diameter pipes with evenly spaced holes. Unlike conventional gravity-fed systems that release a large volume of wastewater at once, LPD systems distribute effluent slowly and evenly, giving the soil adequate time to treat it between doses. This makes LPD systems well-suited for Florida’s sandy soils, high water table areas, and properties where a standard drainfield wouldn’t perform well.
How often does a low pressure dosing system need to be serviced?
We recommend having your LPD system professionally inspected at least once a year. Because these systems have mechanical components — a pump, float switches, a timer, and a control panel — they require more attention than a conventional gravity septic system. Annual service visits allow us to check pump performance, inspect the dosing chamber, verify float operation, and clear any debris from the lateral lines before small issues become expensive ones. Your county may also have specific inspection requirements — we’ll make sure you’re in compliance.
How long does a low pressure dosing pump last?
Most LPD dosing pumps last between 5 and 10 years with proper maintenance. The actual lifespan depends on usage, the quality of the pump, and how well the system has been maintained over time. Keeping the septic tank pumped on schedule (every 3–5 years for most households) reduces solids that can damage the pump. If your pump is approaching or past the 7-year mark, it’s worth having it evaluated — replacing a pump proactively is far less disruptive than dealing with an emergency failure.
What does the alarm on my LPD system mean?
The alarm on your LPD system — typically a light, buzzer, or both on the control panel — activates when the liquid level in the dosing chamber rises above the high-water float. This usually means the pump isn’t activating when it should, the pump has failed, or the system is receiving more water than it can process. When your alarm goes off, reduce water use in the home immediately and call us. Most alarm situations can be resolved quickly, but ignoring them can lead to backups or drainfield damage.
Can a low pressure dosing system be repaired, or does it need to be replaced?
In most cases, LPD system issues can be repaired rather than requiring full replacement. Common repairs include replacing the dosing pump, fixing or replacing float switches, repairing the control panel or timer, and clearing clogged lateral lines. Full system replacement is typically only necessary when the drainfield itself has failed beyond recovery or the overall system design no longer meets current county code requirements. We’ll always tell you honestly what your system needs — repair when repair is the right call, replacement only when it’s truly necessary.
Is a low pressure dosing system required in Florida?
Florida doesn’t require LPD systems on every property, but they are required — or the preferred solution — when site conditions rule out a conventional drainfield. Common triggers include high seasonal water tables, limited lot size, marginal soil percolation rates, or proximity to bodies of water. Many Central Florida properties fall into one of these categories. If your county health department requires an LPD system for your lot, Lapin will handle permitting, installation, and the inspection process on your behalf.
