Irrigation System Inspection: A Florida Home Buyer's Guide

Florida's year-round sunshine is great for your lawn—and most homes in the Orlando area come with an irrigation system that runs year-round to keep it that way. But when you're buying a home in Central Florida, that irrigation system deserves a closer look before you close. A poorly maintained or failing system can quietly run up your water bill, cause root damage, and cost thousands in repairs. Here's what a proper irrigation inspection covers and why it matters.

What an Irrigation Inspection Covers

A thorough irrigation inspection goes zone by zone through the entire system. An inspector or licensed irrigation specialist runs each zone manually to check for proper coverage and function. Key things they look for:

• Sprinkler head coverage and condition — broken, misaligned, or clogged heads leave dry spots and can overspray onto structures or driveways
• Controller and timer settings — outdated or misconfigured controllers often waste water and may not comply with local watering restrictions
• Backflow preventer — required by Florida law, this device protects the drinking water supply from contamination; a faulty or missing unit is a code violation
• Water pressure across zones — low pressure typically signals a leak or a broken line somewhere underground
• Leaks and wet spots — soggy areas in the yard, especially when the system hasn't recently run, often indicate a cracked or broken line

Not every home inspector includes a detailed irrigation check in a standard inspection. If you're buying in Central Florida, ask your Simplispect inspector whether irrigation is part of their scope—or consider requesting a separate review on homes with large or aging systems.

Common Irrigation Problems in Central Florida Homes

After thousands of inspections across the Orlando metro area, these are the irrigation issues that come up most often:

• Broken or missing sprinkler heads — common in older systems, frequently damaged by lawn mowers or vehicle traffic. Usually an inexpensive fix per head, but widespread damage adds up fast.
• Leaking main or zone valves — valve seals wear out over time. A single dripping valve can waste hundreds of gallons per month while staying invisible above ground.
• Outdated controllers — older analog timers can't be programmed for water restriction schedules. Most Central Florida counties have mandatory watering days, and non-compliance can result in fines.
• Poor coverage design — systems installed without professional design often leave dead zones or overlapping coverage that wastes water. This is common in homes where landscaping changed after the original install.
• Backflow preventer failure — these corrode over time. Repair runs $100–$300; replacement can run higher depending on type and size. A missing backflow preventer is a code violation that must be corrected.

What Irrigation Repairs Actually Cost

Minor issues—a broken sprinkler head, a loose fitting—are usually inexpensive to fix, often under $100 each. The bigger concerns are underground leaks, failed zone valves, and controller replacements.

A full irrigation system overhaul on a typical Central Florida home runs $1,500–$5,000 or more depending on the number of zones and the extent of the damage. If an inspection turns up major issues before you close, that's legitimate negotiating leverage—or at minimum, a heads-up so the repair cost doesn't blindside you three months into ownership.

Water bills in Orange, Osceola, and Seminole counties can run $150–$300+ per month for homes with active irrigation needs. A faulty system running inefficiently can push that significantly higher. Catching problems early matters.

When to Request a Separate Irrigation Inspection

For most standard homes, a basic check during the home inspection is enough to flag obvious issues. But a dedicated irrigation review is worth the extra investment if:

• The home has a large lot (half-acre or more)
• The system is 10+ years old
• You notice visible wet spots or dry patches in the yard
• The seller's water bill seems unusually high for the area
• The property is in a new development where irrigation was added by the builder

Properties in communities like Lake Nona, Dr. Phillips, Horizon West, and Celebration often have full multi-zone systems that benefit from a specialist's eye. A licensed irrigation contractor typically charges $75–$150 for a zone-by-zone inspection and report.

Protecting Your Investment Before You Close

An irrigation system is easy to overlook when you're focused on the roof, the HVAC, and the foundation. But in Florida's climate, a functioning irrigation system is part of the home's infrastructure. A code-compliant, properly maintained system keeps your lawn healthy, your water bill manageable, and your home in good standing with local water management authorities.

Make sure you know what you're inheriting before you close—not after the first $400 water bill arrives.
