Proper installation depth and adequate trajectory are important for efficient sprinkler head performance. Sprinkler heads with 3" risers cannot function properly if set or positioned 4"-5" below grade. Factory specified performance (trajectory, radius, distribution uniformity) when applying water will be negatively impacted. In addition, the existence of considerably below grade sprinkler canisters can pose hazards for golfers and workers alike. With a large portion of our turf dormant in the cool season months we have ramped up our focus on raising and leveling priority sprinklers.
