Irrigation Valve Replacement

What This Service Involves

A bad valve is the most common reason a zone runs constantly, won't turn on, or floods a corner of the yard. In Western Washington, mineral buildup and winter freeze cycles wear out valve diaphragms and solenoids faster than many homeowners expect. We diagnose whether the fault is the diaphragm, solenoid, or wiring, then replace the valve with a durable, serviceable unit sized to your flow. After swapping the valve we verify clean actuation and check that no water hammer or weeping remains.

Benefits

Our Process

1) Isolate and test the malfunctioning zone; 2) Excavate and inspect the valve box; 3) Diagnose diaphragm, solenoid, or wiring fault; 4) Replace valve and reconnect wiring; 5) Actuate and verify clean open-close cycles

What Affects the Cost

Number of valves needing replacement; Valve size and quality tier; Depth and accessibility of the valve box; Solenoid and wiring repairs required; Emergency versus scheduled service

Best Time of Year

Address failing valves in spring before peak watering, or in fall before winterization to avoid a stuck-open zone freezing.
