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 cap “pops up” to release water when pressure builds. Cap closes once flow diminishes and stays closed when not in use to prevent debris and 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. Cap and cover made of polyethylene; elbow 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. Use our free drainage calculators, Home Drainage Center, and NDS Stormwater Drainage mobile app to find the best solution for your specific drainage problem. NDS, founded in 1972, is the preferred choice of professionals and offers proven products, tools, and expert support to help you get the job done right.
Provides a downstream point of release for water collected upstream
Elbow connects to 4-in sewer and drain pipe and connects to other pipe types using appropriate adapters
Releases collected water up to 40 GPM
Cap on cover pops up as high as 1-in once water pressure builds; closes as flow diminishes
Outside flange prevents grass from growing over the cover
Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather
Cover made of high-density polyethylene (HDPE) and elbow made of polyvinyl chloride (PVC); both use a combination of virgin and recycled content treated with UV inhibitors to prevent fading and cracking
Comes with 1 Pop-Up Drainage Emitter and attached elbow
Use multiple Pop-Up Drainage Emitters for larger drainage problems
