Your irrigation system works hard in Southwest Florida’s heat, running hundreds of cycles per year to keep your lawn and landscape alive. But when something goes wrong, the signs aren’t always obvious — a slow leak underground or a misaligned head can waste thousands of gallons before you notice. Here are seven signs your irrigation system needs professional repair before a small issue becomes a big problem.
1. Brown or Yellow Patches in an Otherwise Green Lawn
If you have dry, brown patches surrounded by healthy green grass, one or more sprinkler heads likely aren’t reaching that area. Common causes include a clogged nozzle, a head that’s sunk below grade, or a head that’s been knocked out of alignment by a mower. This is one of the easiest problems to fix — but if ignored, you’ll lose turf in those spots.
2. Unusually High Water Bills
A sudden spike in your water bill — without a change in your watering schedule — often points to a leak in your irrigation system. Underground line breaks are especially common in Southwest Florida due to root intrusion, shifting sandy soils, and damage from lawn equipment. Even a small crack in a mainline or lateral pipe can waste hundreds of gallons per day.
3. Water Pooling or Soggy Areas
If you see water pooling on the surface, a persistently soggy spot in the yard, or areas that stay wet long after the system runs, there’s likely a broken pipe, a stuck valve, or a head that’s spraying too much water in one spot. Pooling water also creates a breeding ground for mosquitoes — a major concern in Florida — and can drown plant roots.
4. Sprinkler Heads That Don’t Pop Up or Retract
Pop-up sprinkler heads should rise when the zone activates and retract flush with the ground when it stops. If heads are stuck up (creating a mowing hazard and getting damaged) or stuck down (not watering), the riser, spring, or seal is likely worn out. In our sandy soil, grit can infiltrate the head casing and cause premature wear.
5. Sputtering or Low-Pressure Spray Patterns
When your sprinklers sputter, mist instead of spray, or have noticeably reduced range, the system is losing pressure somewhere. Potential causes include:
- A cracked or leaking mainline
- A partially closed backflow preventer valve
- Too many heads on a single zone (overloaded)
- A failing pump (if your system uses a well or lake pump)
- Clogged filters on drip irrigation zones
Low pressure means your lawn isn’t getting the water it needs, even though the system is running — you’re paying for water that’s not reaching the grass. If you’re unsure whether sprinklers or drip irrigation would better suit certain zones, consider the differences before upgrading.
6. The System Runs During or After Rain
Florida law requires all automatic irrigation systems to have a functioning rain sensor. If your system is running during a rainstorm or within 24 hours of heavy rain, your rain sensor is likely faulty, disconnected, or overridden. This wastes water, violates SWFWMD regulations, and can lead to fines. A working rain sensor can save you 15–30% on irrigation water use annually.
7. Zones That Won’t Turn On or Off
If a zone won’t activate when you run it manually from the controller, the solenoid valve for that zone may be stuck closed, the wiring may be damaged, or the controller itself may have a bad terminal. Conversely, if a zone won’t shut off, the valve diaphragm is likely stuck open — this causes constant water flow and can flood a section of your yard.
Electrical issues in irrigation wiring are common in our climate. Heat, moisture, and ant colonies (fire ants love to nest in valve boxes) all contribute to wire corrosion and connection failures.
Don’t Wait — Small Problems Get Expensive Fast
Most irrigation repairs are straightforward and affordable when caught early. A leaking head or a stuck valve is a quick fix. But a leak that runs for weeks can erode your yard, kill sections of lawn, and add hundreds to your water bill. If your system is showing any of these signs, our team can diagnose and repair the issue quickly.
