Controller & Timer Repair FAQs
Can you move my controller to a better location?
Often yes, if wiring length and access allow. We discuss routing and enclosure options before relocating.
Will you program for water restrictions?
We set schedules to match your utility or HOA rules and plant needs. Bring any restriction notices when we arrive.
