retaining walls and street curbs. Spring automatically retracts.
The Pop-up Drainage Emitter is easy, safe and an efficient solution.
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 designs include spring-loaded or flip-up caps that open with the hydrostatic pressure of water flowing through the drain pipe, then closes as the flow diminishes. They are safe, trip-free, and efficient solutions with two popular sizes to choose from.
Drainage Emitters allows water captured by grates, catch basins, channel drains, Flo-Well, downspouts and roof gutter systems to flow through the 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 such as a curbside drainage system.
The Emitter is opened by the hydrostatic pressure of water flowing through the drain pipe. As flow diminishes the Emitter closes again. The special design allows the Emitter to open with a negligible amount of pressure. Since the emitter is closed during dry weather, debris and rodents cannot enter the drain pipes.
