Additional Information:

• The co-molded, pressure-activated, Triple-Blade Wiper Seal assures a positive seal without excess “flow-by” which enables more heads to be installed on the same valve. A base seal provides a positive seal during operation and a Triple-Blade Wiper Seal serves to precisely balance flushing, flow-by, and debris protection to optimize performance and durability during the pop-up. Precision-controlled flush at pop-down clears debris from the unit, ensuring positive stem retraction in all soil types.
• The reinforced ratchet mechanism on all models allows easy nozzle pattern alignment without tools, withstands chemicals in recycled water, and prevents pattern misalignment over time.
• Debris pockets in the base of the spray body collect debris and prevent recirculation in the body during operation reducing wear.
• Parts developed to be resistant to corrosion in treated recycled water containing chlorine and other chemicals.
• A strong stainless steel spring provides reliable stem retraction and withstands corrosion.
• Pre-installed 1800 Pop-Top™ flush plug blocks debris from entering after flushing and allows for easy nozzle installation.
• All sprinkler components are removable from the top without special tools, providing for quick and easy flushing and maintenance of the sprinkler.
