POP-UP DRAINAGE EMITTER

Allows water to be diverted and released to water-safe areas away from structures, erosion-prone landscapes, and poor drainage
areas. The special patented design allows the emitter to open with a negligible amount of pressure.
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. Its flat profile blends discreetly into the surrounding landscapes.
