NDS Pop-Up Drainage Emitter with Elbow for 3 in. Drain Pipes, Green Plastic

Take water away from structures, erosion-prone landscapes, and poor drainage areas to discharge from a Pop-Up Drainage Emitter downstream. The Pop-Up Emitter with Elbow connects to 3 in. sewer and drain pipe and 3 in. triple-wall pipe. As water pressure builds, the cap "pops up" as high as 1 in., disperses water at up to 56 GPM, and closes once the flow diminishes. Cap stays closed when not in use to prevent debris and rodents from entering and potentially clogging the drainage system. The flat profile blends discreetly into the surrounding landscape. Rounded contours on interior edges reduce the potential for clogging and internal ribs provide durability and strength. Flange design prevents turf overgrowth. Weep hole at bottom of elbow drains out water left in pipes to prevent stagnation or freezing in cold weather. Cap and cover made of high-density polyethylene (HDPE); elbow made of polyvinyl chloride (PVC). Pop-Up Drainage Emitters are part of a complete drainage system used for stormwater management. They work with pipes, catch basin drains, channel drains, trench drains, and drain grates that 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. NDS offers free tools such as the Home Drainage Center, Calculators, and NDS Stormwater Drainage mobile app to help make your project a success.
