Two lifespans
A stuck valve or broken head can run for days unnoticed, spiking the bill and undermining the foundation and driveway.
Overview
An irrigation system is a lot of small parts that fail one at a time. A yearly audit finds broken heads, misaimed nozzles, and stuck valves before they cost you water and a brown lawn.

Repair or replace
Heads, valves, and controllers all replace one at a time. A poorly designed system that never covered the yard should be redesigned, not just repaired.
The facts
Florida requires a working rain sensor on residential irrigation. Local watering restrictions apply in most St. Johns County utilities, so set the controller to match the allowed days.
