One irrigation zone won't turn on even though others work fine — Chicago, Illinois
When every other sprinkler zone fires on schedule but one stays dead, the problem is isolated to that zone's valve, wiring, or solenoid — not the controller or water supply. A stuck diaphragm, severed low-voltage wire, burnt solenoid coil, or a debris-clogged valve are the usual culprits. A landscaper or irrigation technician traces the circuit from the controller to the valve box, tests solenoid resistance with a multimeter, inspects the diaphragm for tears or mineral buildup, and either repairs or replaces the faulty component to restore full coverage.

Chicago's short growing season and harsh winters mean intensive spring cleanup and fall winterization are essential. Snow removal is a major service, and many properties need drainage solutions to prevent the basement flooding common in the clay-soil flatlands.
