NDS 422G Pop-Up Drainage Emitter with Elbow fits 4-Inch Sewer and Drain Pipe, Works with Drainage Systems Including Catch Basins, Green

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.

• RELEASE WATER AWAY FROM PROPERTY: Capture water upstream and carry it away from structures and poor drainage areas to discharge with the pop-up emitter positioned downstream
• HOW IT WORKS: The pop-up emitter works at a low point of the drainage system to discharge water collected from upstream and help protect property from water damage
• INSTALLATION: Elbow connects to 4 in. sewer and drain pipe and 4 in. triple-wall pipe, connects to other pipe types using appropriate adapters; install with cover flush or slightly below adjacent turf to reduce potential for clipping with lawnmower
• POPS UP TO OPEN, CLOSES WHEN FLOW DIMINISHES: Cap, or cover, lifts up as high as 1 in. once water pressure builds; flat profile design reduces trip hazard and is flush to the ground when properly installed
• ALL-WEATHER SAFE: Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather
