6" NDS Pop-Up Emitter (part 624) with elbow and corrugated pipe adapter provides a reliable, low-profile discharge point for landscape and foundation drainage systems. The spring-loaded cap opens under hydrostatic pressure to release water, then closes to keep debris and pests out. Designed for long-term outdoor use, the flanged cover resists turf overgrowth and the internal ribs and crossbar geometry improve flow while supporting pedestrian traffic.

  • Fits 6" drain pipe; includes elbow and corrugated pipe adapter.
  • Cap and cover: high-density polyethylene (HDPE); elbow: PVC.
  • Spring-loaded cap automatically opens and closes; flange prevents mower interference.
  • Weep hole in elbow drains residual water to reduce freezing risk; UV-resistant construction.

Easy to install at the lowest point of a gravity-fed system, the emitter directs discharge to safe areas away from structures and erosion-prone slopes. Routine inspection and occasional debris clearing keep the unit operating reliably. Technical documentation and spec sheets are available for professional planning and installation.

How is the pop-up cap kept clear of debris and turf?
The wide flanged cover resists turf overgrowth; the spring-loaded cap closes when inactive and internal crossbars help flush debris during discharge.
Can this emitter withstand pedestrian traffic and outdoor exposure?
Yes. HDPE cap and cover with molded-in ribs provide durability and UV resistance; the PVC elbow is corrosion-resistant when properly installed.
