It features an innovative pop-up cap that opens under water pressure to discharge excess water downstream, protecting your property from water damage and erosion. Its low-profile, flush-to-ground design reduces trip hazards, while a built-in weep hole prevents freezing and stagnation in cold weather. Trusted by professionals since 1972, this emitter is a key component in effective stormwater management systems. ## Description Every drainage system needs a point of release to prevent back-up issues. Use the Pop-Up Drainage Emitter to discharge 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 pipe, and the cover “pops up” to release water when pressure builds. Cover closes once flow diminishes and stays closed when not in use to prevent debris & rodents from entering and potentially clogging the drainage system. Weep hole at bottom of elbow drains out water left in pipes to prevent stagnation or freezing in cold weather. Flat profile design blends discreetly into the surrounding landscape. Cover is made of polyethylene; elbow is made of polyvinyl chloride.Pop-Up Drainage Emitters are a part of a complete drainage system that help with stormwater management. They work with pipes, catch basin drains, channel drains, trench drains, and drain grates to filter, capture, and convey excess water to drain pipes; the pipes carry the water downstream to discharge with a Pop-Up Emitter, or to percolate into the ground with a dry well or infiltration trench.Find the right drainage solution for your needs with our NDS Home Drainage Center tool at ndspro.com/home-drainage.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reputable product. *by J***N on September 26, 2025* Installs easily and functions as advertised.
