Common Questions
What is the most reliable sprinkler head brand?
Rain Bird carries the stronger reputation among irrigation professionals for rotor-head durability and arc stability — one contractor's summary on a sprinkler trade forum was simply "Rain Bird stuff just works." Orbit's real strength isn't a head-to-head rotor competitor — it's the B-hyve smart controller line, a genuinely strong value pick. Detailed comparison →
How do I choose a sprinkler system for my USDA zone?
Zones 1–5 need freeze-rated systems with blowout ports for mandatory winterization before first frost. Zones 6–9 suit most residential in-ground and oscillating systems. Zones 10–13 perform best with drip irrigation and a smart controller that adapts to soil moisture conditions. Use our Zone Calculator → for a tailored recommendation.
Are smart sprinkler controllers worth the investment?
For zones 5–10, generally yes. EPA WaterSense certification requires at least 20% savings over a conventional controller, and EPA's own case-study data shows real-world households saving up to 15,000 gallons per year after switching. At $170–230 retail, most owners see the hardware cost paid back within one to two seasons, faster in tiered-water-pricing areas. Savings are smallest in zones 1–4 where irrigation seasons are short.

Do robotic lawn mowers work with irrigation systems?
Yes — Husqvarna Automower 430X integrates with Rachio 3 via IFTTT to pause mowing automatically during watering cycles. Gardena SILENO models sync with the Gardena smart hub. This integration category is new and growing rapidly. We track all supported combinations in our Robotic Systems hub →
What separates Rain Bird and Orbit?
Rain Bird is built for longevity and consistent pressure — the contractor default. Orbit is 30–40% cheaper with good performance for typical suburban lawns. Full zone-by-zone suitability and warranty comparison: Rain Bird vs Orbit →
