Quick answer: It is often useful to identify and document sprinkler problems before winter shutdown while the system can still be operated. Whether a repair should be completed immediately depends on the problem, weather, system condition and the risk of leaving the defect until spring.
Why testing before shutdown helps
Running the system can reveal broken heads, leaking pipe, valves that will not close, weak zones and controller or wiring problems. Once the system is winterized, some symptoms cannot be reproduced until it is activated again.
Some problems should not be ignored
Active leaks, components that prevent proper shutdown, or damage that interferes with winterization may need attention before the system is put away for the season.
Other repairs may be planned for spring
Non-urgent coverage adjustments or landscape-related changes can sometimes be documented and addressed during spring activation.
