NDS 321 - 3" Pop-up Drainage Emitter with Elbow

NDS Pop-Up drainage emitters act as the discharge point of a drainage system, opening easily when needed to allow water to flow freely from the pipe and away from structural foundations. The patented spring-loaded cap opens with the hydrostatic pressure of water flowing through the drain pipe, then closes as the flow diminishes. It allows water to be diverted and released to water-safe areas away from structures, erosion-prone landscapes, and poor drainage areas. The NDS pop-up drainage emitter with elbow is an easy, safe, and efficient solution to any drainage needs.

Features

• Pop-up emitter cover consists of a spring-loaded cap and wide flange to prevents turf overgrowth
• Engineered crossbar design underneath helps maximize flow while flushing out debris
• Molded-in crossbar geometry along with internal ribs provide exceptional durability; supports pedestrian traffic including lawn tractors when properly installed
• Use with an elbow and weephole to drain residual water and help prevent stagnation and potential freezing of residual water
• Manufactured from 100% recycled HDPE
• Reduces trip hazard posed by open drain
• Pop-up top keeps rodents and debris out of system
• Low-rise to avoid interfering with mowers
• Color can be matched to surrounding landscape
• Material: Polypropylene
• Color: Green
• Height: 6-1/4"
• Fits 3" sewer and drain pipe
• Ideal for discharging excess water from stormwater management system.

How do pop-up drainage emitters work?

Pop-up Drainage Emitters allow water captured by grates, catch basins, channel drains, Flo-Well, EZflow, downspouts and roof gutter systems to flow through drainage pipe and away from structural foundations to safe or useful areas. For example, water can be routed from a low area next to a foundation to a water-safe area in the landscape, or a curbside drainage system where allowed. The emitter opens under minimal hydrostatic pressure from water through upstream drainage pipes; the emitter closes as flow diminishes. The special patented design allows the Emitter to open with even the smallest flows. Since the Emitter is closed during dry weather, debris and rodents cannot enter the drain pipes. Spring automatically retracts – closes and prevents damage from lawn mowers. It's flat profile blends discreetly into the surrounding landscapes.
