One irrigation zone won't turn on even though others work fine — Barcelona, Catalonia
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.
Waarom dit veel voorkomt in Barcelona
Barcelona's private gardens concentrate in the upper districts (Sarrià, Pedralbes) and the hillside Tibidabo belt, where terraced plots and Mediterranean planting require specialist care. Rooftop terraces (terrats) and balcony greening are common in the dense Eixample, and water-efficiency rules increasingly govern irrigation under Catalan drought planning.
