POP-UP DRAINAGE EMITTERS
3" & 4" Pop-up Drainage Emitter
The Pop-up Drainage Emitter is an easy, safe and efficient solution
that allows water to be diverted and released to water-safe areas
away from structures, erosion-prone landscapes and
poor drainage areas.
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.
