Plan for Adequate Spray Coverage Odd shaped areas can be effectively covered using adjustable pattern nozzles that adjust from 0 to 360 degrees. Head-to-head coverage
Use Watering Zones Water supply capacity = 17 GPM (gallons per minute) Landscape requires 28 pop-up sprinkler heads Each head delivers 1.5 GPM 28 x 1.5 = 42 GPM (total water volume needed) Break landscape into manageable sections or “zones” → 42 ÷ 17 = 2.47 → Need 2.47 or 3.00 water zones for proper coverage
