Try to choose a sprinkler nozzle based on the spray pattern, distance, and flow rate your zone needs. Start by matching the nozzle to the area you’re watering, such as quarter, half, or full-circle coverage, and choose a radius that reaches the next sprinkler head without overspraying sidewalks or buildings. Also check the nozzle’s gallons-per-minute rating to keep the zone balanced and within your system’s pressure and flow limits.
