NDS 430 Pop-Up Drainage Emitter with Elbow & Universal Adapter (3–4 in)

The NDS 430 Pop‑Up Drainage Emitter with Elbow and Universal Adapter provides a reliable downstream discharge point for landscape and stormwater drainage systems. Its spring‑loaded cap opens under hydrostatic pressure to release water away from foundations and closes when flow diminishes to keep debris and pests out.

• Fits multiple pipe types: Included adapter connects to 3" and 4" corrugated pipe, 3" and 4" sewer & drain pipe, 4" Sch. 40 pipe, and 3" or 4" triple‑wall pipe.
• High flow capacity: Spring‑loaded cap can discharge up to 56 GPM; cap rises approximately 1" to release flow.
• Durable construction: Cap and cover are high‑density polyethylene (HDPE); elbow is PVC for reliable performance.
• Low‑profile, mower‑safe design: Flush flange reduces trip hazard and helps prevent grass overgrowth.
• Freeze and clog protection: Elbow includes a small weep hole to drain remaining water and reduce stagnation or freezing; cap closes to block debris and rodents.
• Easy install: Elbow comes pre‑assembled for simple connection at the system's low point; place in a water‑safe discharge area away from structures.

Use the NDS 430 when you need a simple, effective outlet that balances high discharge capacity with a low profile and durable materials. Refer to the NDS installation details and spec sheet (link included in product resources) for placement and performance guidance.
