What to check first
Check whether the controller activates the valve and whether the source can maintain flow.
What usually helps
Target the specific failed component, then retest all affected sprinklers.
Safety and important limitations
Unnecessary digging can damage healthy pipework and planting.
When to get site-specific help
Water system problems often involve more than one component. A site visit can confirm flow, pressure, electrical condition and installation layout before suggesting repairs or replacement parts.
