Product Details: NDS 3" & 4" Pop-up Drainage Emitter

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 NDS design allows the Emitter to open with a negligible amount of pressure. The good thing about pop-up emitters is that if there’s no steady flow of water, the lid stays shut. That means no debris can make its way into the pipe. It’s a great alternative to traditional drain grates that have a tendency to collect rocks, dirt, or leaves that'll eventually clog the line. An alternative to concrete drains, this polypropylene solution is weather durable and long-lasting. Typical applications include pools, spas, patios, tennis courts, and athletic fields.
