Irrigation Valve / Sprinkler Head repair in Orlando, FL

Verified against official sources · Updated 2026-07-06

Thinking about an irrigation valve / sprinkler head repair in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.

Do you need a permit?

It depends on the exact scope. Orange County and the City of Orlando require permits for more than most homeowners expect — and the rules change. Check the county's official "Do I Need a Permit?" page or call your local building department before starting work.

Key facts before you start

Rain Bird head swap: apply thread tape, screw new head on HAND-TIGHT only (no wrench), then flush before finishing — pull up the stem, remove the nozzle, run water 2-5 min to purge soil from the line, THEN install the nozzle. Skipping the flush clogs the new nozzle immediately.
Never mix rotors and spray heads on the same zone/valve — spray heads precipitate ~3x faster, so one area floods while the other stays dry (Rain Bird: avoid mixing components with different precipitation rates on one valve). Replace like-for-like, or use matched-precipitation (MPR) nozzles.
Stuck solenoid swap needs NO digging or valve removal: shut water+controller power, twist old solenoid counterclockwise off the valve bonnet, screw new one in, splice with waterproof grease caps. It's 24VAC — no polarity, either solenoid wire to either field wire (Hunter official procedure).
Zone valve that won't shut off or weeps usually is NOT a bad valve — it's debris caught between the diaphragm and seat (Hunter). Shut off the MAIN water first (never open a pressurized valve), remove bonnet, rinse diaphragm, check for tears/wrinkles, and clear the exhaust port with a paperclip-size wire before buying anything. Buy a diaphragm kit only if torn.
Orlando watering days are legally restricted and district-dependent — Orange County spans BOTH St. Johns (SJRWMD: 2 days/wk during daylight saving, 1 day/wk in winter, odd addresses vs even get different days) and South Florida (SFWMD: 2-3 days/wk) districts; both ban 10am-4pm watering and drought orders can tighten to 1 day/wk. Have the user verify their address's current schedule with their district/utility after any repair before reprogramming the controller.
Permits (Orange County): repairing/servicing existing heads and valves needs no permit, but a NEW or replacement underground irrigation system requires an irrigation (plumbing) permit, and installing/replacing the required backflow preventer (PVB, double-check, or RP per hazard level) is also permitted work — route those to a licensed contractor, not DIY.
