Dead zone diagnosis
A non-working zone can come from the controller, valve, wiring, pressure, or a leak
Homeowners often describe the problem as “one sprinkler zone not working,” but the repair path depends on what the zone is doing. A zone that never starts is different from a zone that stays on, runs weak, floods one area, or only works manually.
- One zone will not turn on while other zones run
- Zone starts manually but not on the programmed schedule
- Zone stays on after the controller shuts off
- Weak spray or dry spots are limited to one zone
- Valve box is wet, buzzing, buried, or hard to access
- Recent digging, startup, winter damage, or controller changes happened
Start with the pattern
If only one zone is affected, mention whether it is the front yard, back yard, side yard, beds, or drip area. If several zones fail, include that too — it may point toward the controller, water supply, common wire, or rain sensor instead of one valve.
Common causes when one zone is not working
Valve or solenoid
A stuck, clogged, leaking, or failed valve/solenoid can keep one zone from opening or closing.
Wiring or controller output
Bad splices, cut field wires, common-wire issues, or a controller terminal can interrupt one or more zones.
Leak, clog, or pressure loss
A broken pipe, clogged head, partly closed valve, or supply issue can make one zone spray weakly or leave dry spots.
