The NDS 4" Pop-Up drainage emitter with 4" S&D Elbow acts 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.

  • 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
  • Color can be matched to surrounding landscape
  • Spring automatically retracts
  • Ideal for discharging excess water from storm water management system.

Just what I needed

After Hurricane Milton I noticed the grate to my French drain was missing. Looked all over the Internet for one and finally found one at Master Landscape Supply which was priced reasonably. Got it two days later! Thank you for your prompt response.
