4" NDS Pop-Up Emitter with Elbow & Universal Adapter (Green) (Each)

Also Available: Contractor Pack of 20 emitters NDS430_BX 

Opened by the hydrostatic pressure of water flowing through the drain pipe. As flow diminishes the Emitter closes again. The special patented design allows the Emitter to open with a negligible amount of pressure. Since the Emitter is closed during dry weather, debris and rodents cannot enter the drain pipes.
