Sprinkler Repair & Maintenance
Broken heads, leaking valves, wiring issues — we diagnose and fix it fast.
Fast Diagnosis, Lasting Repairs
When a sprinkler zone stops working or a head is spraying sideways into your driveway, you need it fixed — not next month, but this week. EMI Irrigation provides same-week repair service for most issues in the greater Billerica area. We start every repair call with a systematic zone-by-zone diagnosis. We check water pressure at the source, inspect valve operation, test wiring continuity from controller to valves, and visually inspect every head in the affected zone. Once we identify the problem, we explain what needs to be done and give you a clear price before starting any work.
Common Issues We Fix
Sprinkler systems in Massachusetts take a beating from freeze-thaw cycles, lawn mower strikes, root intrusion, and simple wear over time. The most common repairs we handle include broken or tilted spray heads, leaking zone valves, cracked PVC lateral lines, faulty solenoids, corroded wire splices, and controller malfunctions. We also repair backflow preventer leaks, replace worn diaphragms, and fix low-pressure problems caused by partially closed valves or municipal supply changes. If your system is producing dry spots, flooding, or uneven coverage, there is almost always a specific, fixable cause.
Preventive Maintenance
The best way to avoid emergency repairs is regular seasonal maintenance. Our membership plans include annual spring activation with a full system check, a mid-season inspection, and fall winterization. During each visit, we test every zone, adjust head positions for seasonal growth, check for leaks, and verify controller programming. Catching a hairline crack or a slow-leaking valve early saves hundreds in emergency repair costs later. Homeowners in Lexington, Concord, Arlington, and Waltham rely on our maintenance programs to keep their systems running trouble-free season after season.
