4″ Pop-Up Drainage Emitter


Use the Pop-Up Drainage Emitter downstream to discharge water captured upstream and carried 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 4 in. triple-wall pipe. As water pressure builds, cap “pops up” to release water at up to 56 GPM and closes when 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 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.
