Service Overview
Irrigation System Plumbing Backed by 65+ Years of Local Experience
Irrigation systems depend on more than just heads and timers — the plumbing connection to your home or building's water supply is what determines how reliably and efficiently your system performs. A poorly installed supply connection, an aging or leaking irrigation water line, a missing or failed backflow preventer, or a cracked pipe running underground can waste thousands of gallons, spike your water bill, undermine your landscaping, and put your drinking water at risk. In Florida, where lawn irrigation accounts for a significant share of residential water use, the plumbing infrastructure behind your irrigation system needs to be installed and maintained to the same standard as any other part of your home's plumbing.
Lapin Services is a licensed plumbing contractor (CFC1428594) with deep experience in irrigation system plumbing across Orlando and Central Florida. We handle connections to the main water supply, installation and repair of dedicated irrigation lines, backflow preventer installation and compliance, and troubleshooting and repair of leaks, pressure problems, and damaged underground pipe. Our licensed plumbers ensure every irrigation plumbing connection meets Florida building code and local utility requirements — protecting your property, your water supply, and your investment. With 65+ years in the business and a 4.9★ rating from over 1,000 customers, Lapin delivers the expertise and accountability your irrigation system needs.
Problems We Solve
Common Irrigation System Plumbing Problems We Fix
Here are the issues our team commonly finds and resolves during irrigation system plumbing calls across Central Florida.
Leaking or Broken Irrigation Supply Line
Underground irrigation supply lines crack, shift, and corrode over time — especially in Florida's sandy soil and under the stress of freeze-thaw fluctuations and tree root intrusion. A leaking irrigation line can saturate the soil, cause soggy spots in your yard, or quietly drive your water bill up for months before you notice. Lapin locates the break, excavates precisely, and repairs or replaces the damaged section with code-compliant materials.
Missing or Failed Backflow Preventer
Florida law requires a properly functioning backflow preventer on every irrigation system connected to a potable water supply. When the preventer is missing, incorrectly installed, or has worn internal components, contaminated irrigation water can flow backward into your drinking water supply — a serious health hazard and a code violation. Lapin installs, repairs, and certifies backflow prevention assemblies to bring your system into full compliance.
Low Water Pressure Affecting Irrigation Performance
Weak coverage, zones that won't activate, or heads that barely pop up are often symptoms of a plumbing problem — not just a timer or controller issue. A partially closed isolation valve, undersized supply line, or leak upstream of the manifold can starve your irrigation system of the pressure it needs. Lapin diagnoses the plumbing root cause and restores proper pressure so every zone performs as designed.
New Irrigation System Requiring Water Supply Connection
Installing a new irrigation system means tying into your home's water supply — and that connection must be made by a licensed plumber to meet Florida building code. Improper taps, unprotected connections, or incorrectly sized supply lines can void permits, fail inspections, and create long-term reliability problems. Lapin handles the plumbing portion of new irrigation installations correctly from the start, including the meter tap, supply line, isolation valve, and backflow preventer.
Irrigation Valve or Manifold Leaks
Valve boxes and manifolds are common failure points — solenoid valves develop internal leaks, fittings crack under UV exposure or soil pressure, and manifold pipes split over time. Visible puddles near valve boxes, constant running water sounds, or zones that won't shut off are all signs of a valve or manifold plumbing issue. Lapin inspects the full manifold assembly, replaces failed components, and ensures the repair holds.
When to Call
Signs Your Plumbing System Needs Professional Attention
If you notice any of these warning signs, schedule irrigation system plumbing before the problem becomes more disruptive or expensive.
Your Water Bill Has Spiked Without Explanation
An unexplained increase in your water bill — especially during months when you haven't changed your irrigation schedule — is one of the most common indicators of a hidden irrigation plumbing leak. Cracked underground supply lines can release hundreds of gallons per day without any visible surface sign. Lapin locates the source and stops the waste before it compounds further.
You Have Wet or Soggy Spots in Your Yard
Persistently saturated ground between irrigation cycles, especially in a specific area of your yard, often points to a subsurface pipe leak or a valve that's not seating properly. Left unaddressed, standing water can damage your foundation, breed pests, and kill grass and plant roots. Lapin pinpoints the irrigation plumbing issue and restores proper drainage.
Your Irrigation System Has No Backflow Preventer
If your irrigation system was installed without a backflow preventer — or if you're not certain one is in place — it's a code violation and a health risk. Florida's water utilities actively enforce this requirement, and a violation notice can result in service interruption. Lapin inspects your system, installs the appropriate backflow prevention assembly, and ensures you're compliant and on record.
You're Installing a New Irrigation System
New irrigation system installations require a licensed plumber to make the water supply connection under Florida law. If a landscaping or irrigation contractor has quoted you a full installation but is not a licensed plumber, the water supply tap, supply line, and backflow preventer installation must be handled by a licensed plumbing contractor separately. Lapin coordinates directly with your irrigation contractor to complete the plumbing portion efficiently and on schedule.
Your Irrigation Zones Have Uneven or Weak Coverage
If some zones cover their area well while others are weak or erratic, the problem may lie in the plumbing — an undersized line, a partially failed valve, or a leak reducing pressure to specific zones. Before replacing heads or reprogramming a controller, have a licensed plumber rule out supply and manifold issues to avoid unnecessary expense.

FAQs
Irrigation System Plumbing FAQs
Do I need a licensed plumber to connect my irrigation system to the water supply?
Yes. In Florida, any connection to a potable water supply line — including irrigation system tie-ins — must be performed by a licensed plumbing contractor. This includes the supply tap, isolation valve, and backflow preventer installation. Many irrigation and landscaping companies are not licensed plumbers and cannot legally perform this work. Lapin holds plumbing license CFC1428594 and handles irrigation water supply connections for new and existing systems throughout Central Florida.
What is a backflow preventer and why does my irrigation system need one?
A backflow preventer is a device installed on your irrigation supply line that stops contaminated water from flowing backward into your potable water supply. Irrigation water can pick up fertilizers, pesticides, and soil bacteria — if water pressure drops or reverses for any reason, that water can flow back into your home’s drinking water without a preventer in place. Florida law requires a properly functioning backflow preventer on all irrigation systems connected to a potable supply, and annual testing is required in most jurisdictions.
How do I know if my irrigation system has a water line leak?
Common signs of an irrigation water line leak include unexplained increases in your water bill, wet or soggy patches in your yard that persist between watering cycles, visible erosion or sinkhole-like depressions in the lawn, or noticeably reduced pressure in your irrigation zones. Some leaks occur deep underground with no visible surface sign — if your water usage has increased without a clear explanation, it’s worth having a plumber inspect your irrigation supply line.
Can Lapin help if a landscaping company installed my irrigation system without a proper plumbing connection?
Yes. This is a common situation in Central Florida. If your irrigation system was installed without a permitted plumbing connection, a missing or improperly installed backflow preventer, or with an unpermitted tap on the water main, Lapin can assess the existing installation, perform any required corrections, and bring the system into compliance with Florida building code and local utility requirements. We can also coordinate with your municipality or utility if permits need to be pulled retroactively.
What types of backflow preventers are used on irrigation systems?
The most common backflow prevention assemblies used on residential and commercial irrigation systems in Central Florida include pressure vacuum breakers (PVB), reduced pressure zone (RPZ) assemblies, and double check valve assemblies. The correct type depends on your system’s hazard classification, the local utility’s requirements, and the installation location. Lapin’s licensed plumbers select and install the appropriate assembly for your specific situation and ensure it meets all applicable code requirements.
Will Lapin work alongside my existing irrigation contractor?
Absolutely. Lapin regularly coordinates with irrigation contractors, landscaping companies, and general contractors who need a licensed plumber to handle the water supply connection portion of an irrigation project. We handle our scope — the supply line, isolation valve, backflow preventer, and any required permits — and coordinate timing with your contractor so the project stays on schedule.
How long does it take to repair an irrigation water line?
Most irrigation water line repairs are completed in a single visit. Simple valve or fitting repairs typically take one to two hours. Underground pipe repairs require locating the break, targeted excavation, and repair or replacement of the damaged section — these generally take a few hours depending on depth, access, and pipe length involved. Lapin minimizes excavation and restores the area as cleanly as possible once the repair is complete.
Does Lapin serve areas outside of Orlando?
Yes. Lapin Services serves all of Central Florida, including Orange, Osceola, Seminole, Lake, and surrounding counties. Whether you’re in the Orlando metro, a surrounding suburb, or a more rural part of Central Florida, our licensed plumbers are available for irrigation system plumbing installations, repairs, and backflow compliance.
