• UP TO 40 GPM CONTROLLED WATER DISCHARGE Supports stormwater release up to 40 gallons per minute. Provides a designated yard drainage outlet to redirect runoff away from foundations, low yard areas, and erosion-prone sections.
• AUTOMATIC POP-UP CAP WITH FLUSH LAWN PROFILE Cap rises up to 1 inch under internal water pressure and closes automatically as flow decreases. Closed position remains flush with ground level to help reduce trip hazards and minimize mower interference.
• DESIGNED FOR PEDESTRIAN & LAWN EQUIPMENT USE When installed at proper grade, supports pedestrian traffic and light lawn tractor use. Exterior flange helps reduce grass overgrowth around the emitter for consistent cap operation.
