The NDS 4" Pop-Up Drainage Emitter with 4" elbow fits sewer and drain pipe. NDS Pop-Up drainage emitters act as the discharge point of a drainage system, opening easily when needed to allow water to flow freely from the pipe and away from structural foundations. The patented spring-loaded cap opens with the hydrostatic pressure of water flowing through the drain pipe, then closes as the flow diminishes. It allows water to be diverted and released to water-safe areas away from structures, erosion-prone landscapes, and poor drainage areas. The NDS pop-up drainage emitter with elbow is an easy, safe, and efficient solution to any drainage needs.

Additional Features:

  • Manufactured from 100% recycled HDPE
  •  Reduces trip hazard posed by open drain
  •  Pop-up top keeps rodents and debris out of system
  •  Low-rise to avoid interfering with mowers
