Larger yards need more zones (groups of sprinkler heads that run together), with each zone adding a valve, pipe runs, and heads.
Rotary heads cover more area per head but cost more ($5–$15 each). Pop-up spray heads are cheaper ($3–$8) but cover less area, requiring more heads.
A backflow prevention device is code-required in most areas to protect your drinking water supply — it adds $100–$300 to the project.
Wi-Fi smart controllers ($100–$300) adjust watering based on weather data, saving 20–50% on water usage compared to basic timers.
Rocky soil, tree roots, existing landscaping, and underground utilities make trenching more difficult and time-consuming.
