Featuring a pop-up polyethylene cover that automatically opens and closes with water pressure, it connects directly to 4-inch drain pipes without extra fittings. Built to withstand pedestrian and lawn tractor traffic, it includes a weep hole to prevent freezing and water stagnation, making it an essential upgrade for effective, low-maintenance drainage systems. ## Description Every drainage system needs a point of release to prevent back-up issues. Use the Pop-Up Drainage Emitter to safely discharge collected water away from structures, erosion-prone landscapes, and poor drainage areas. The Pop-Up Drainage Emitter with Elbow connects to 4 in. sewer and drain pipes. When water pressure builds, the cover “pops up” as high as 1 in. to release water at up to 40 GPM. Cover closes automatically once the flow diminishes. Cover is made of polyethylene and the elbow is made of polyvinyl chloride. ## Features - Works with a complete drainage system to release collected stormwater runoff and standing water to a discharge point before it causes costly property damage. Provides collected water a point of release at water-safe areas downstream and away from structures, erosion-prone landscapes, and poor drainage areas - Elbow connects to 4 in. sewer and drain pipe, no fitting necessary; connects to other pipe types using appropriate adapters. Releases collected water up to 40 GPM. Supports pedestrian traffic including lawn tractors, when properly installed - Pop-Up Drainage Emitter comes with elbow securely attached for an easier install.

I live in Wisconsin and worry the residual water may freeze. Thanks** A: I have 3 of these (similar buried systems) all running down angle underground and yes they can freeze up (residual water at/around the pop up, “Colorado clay” stops up the little relief drain hole) although just 1 of the lines seems to show drain water backup up to the downspout during melt…anyway, for winter I pull off the 4” at the bottom of the downspouts and slip on another adapter and length of 4” downhill” that is just open at the end (Maybe there’s a better way? because yes we have 4” laying on top of ground level that can trip over etc.! **Q: How does the water make its way to the discharge with a hole in the bottom ?** A: The hole in the bottom is so small that the vast majority the water will be emitted from the top. The hole only allows a small amount to drain, which is important after that heavy flow has stopped. **Q: My down spout is rectangular is there a piece to connect with that shape on one end and circular on the other?** A: Correct. There is a rectangular piece that fits on the downspout. Then you need your hose to connect to the drainage **Q: Anybody use this in cold weather climates. Does it freeze up?** A: No. Have had 2 of then for several years in NY state. Never a problem. However they are used as an overflo for a drain pipe. I have no idea what happens when they are under a foot of snow. IBut f there is running water they won't freeze. ## Frequently Bought Together - NDS 422G Pop-Up Drainage Emitter with Elbow fits 4-Inch Sewer and Drain Pipe, Works with Drainage Systems Including Catch Basins, Green - NDS 451 HDPE Corrugated Adapter, 4-Inch, for Spigot X 4 inch Corrugated Hub Connections, for use with 4 inch Drain Pipes & Fittings, Black - NDS 420C Pop-Up Drainage Emitter, fits 3-Inch and 4-Inch Sewer and Drain Fittings, Works with Drainage Systems Including Catch Basins and Channel Drains, Green --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/257364983-nds-emitter-with-elbow](https://www.desertcart.us/products/257364983-nds-emitter-with-elbow) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-28*
