Common Sprinkler Problems We Fix
In seven-plus years servicing South Florida irrigation systems, we've seen every failure mode. Here are the most common issues we diagnose and repair:
- Broken or clogged sprinkler heads — cracked bodies, stuck pop-ups, misaligned arcs, clogged nozzles
- Valve failures — zones not turning on, zones running continuously, failed solenoids
- Controller malfunctions — zones not activating, error codes, wiring faults, surge damage
- Main line and lateral line leaks — wet spots between heads, pressure loss across zones
- Backflow preventer failures — leaking relief valves, failed check assemblies, missed annual certification
- Pump problems — loss of prime, cavitation, motor failures on well-fed systems
- Pressure issues — low pressure causing poor coverage, high pressure causing head blow-outs
- Wiring faults — cut wires from landscaping crews, rodent damage, corroded wire nuts
Our Diagnostic Process
Sprinkler problems often have one root cause affecting multiple symptoms. We run a full system audit on every repair visit — not just the zone you called about. We manually activate every zone, check each head for proper arc and radius, measure pressure at the controller and at individual heads, and inspect the backflow preventer and main shutoff.
This approach finds issues before they cause further damage and gives you a complete picture of your system's health. You'll know exactly what was fixed, what's in good shape, and what to watch in coming months.
Sprinkler Maintenance Programs
The best repair is prevention. We offer quarterly and bi-annual maintenance visits that keep South Florida irrigation systems running at peak efficiency year-round. Each visit includes:
- Full zone activation and head-by-head inspection
- Arc and radius adjustment on all rotors
- Nozzle cleaning and replacement as needed
- Controller schedule review and seasonal adjustment for SFWMD compliance
- Backflow preventer visual inspection
- Valve box check and clearing
- Written service report with photos
Backflow Preventer Testing & Certification
Florida law requires annual testing and certification of irrigation backflow preventers. GroundLogic is certified to test, repair, and certify Febco, Wilkins, Watts, and Apollo backflow preventers. We file the certification directly with your water utility — you don't have to do anything.
Same-Brand or Better Replacements
When heads, nozzles, or valves need replacement, we use original Rain Bird or Hunter parts — not off-brand substitutes. This ensures your system maintains consistent precipitation rates and doesn't develop coverage gaps over time.
