The Story
NDS 420 3-inch pop-up drainage emitter directs excess water away from your property. Durable polypropylene construction for reliable yard drainage
Permits 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.
Opened by the hydrostatic pressure of water flowing through the drain pipe. As flow diminishes the Emitter closes again. The special patented 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.
Specifications:
- Material: High Density Polypropylene (HDPE)
- Colors: Green
- Fits: 3” and 4” sewer and drain pipe/fittings
- Flow Rate: 40 G.P.M
- UV inhibitor
- Spring: Stainless Steel
- Spring Tension: 0.04 PSI or 1” water required to rise cap.
