Interactive troubleshooting
Sprinkler Diagnostic Tool
Answer a short sequence of questions. The tool does not declare a failed part. It narrows the most useful troubleshooting path and explains why that path fits the symptom.
Guided diagnostic
Start with what you can observe.
No model number is required for the first pass.
How the result is chosen
The tool uses symptom scope and system behavior to route you toward the most relevant hub or guide. It does not infer a specific failed part from one answer.
When brand or model matters
After the generic path is clear, use a brand page if controller behavior, terminals, adjustment, parts, or service steps differ by model.
