3" drainage emitter. The emitter allows water captured by grates, catch basins, channel drain, downspouts, and roof gutter systems to flow through the drainage pipe and away from structural foundations to safe or useful areas. The emitter is opened by the hydrostatic pressure of water flowing through the drain pipe. As flow diminishes, the emitter closes again. The emitter does not rise high enough to interfere with mowers and its green color blends into the surrounding landscape. Fits smooth wall PVC sewer and drain pipe. Includes pop-up drainage emitter with either 3" or 4" PVC S & D elbow. 3" ---- 1. 海外直輸入品となりますので、新品であっても、パッケージに多少のダメージがある場合もございますが、商品本体には問題ございませんのでご安心ください。2. 日本国内でのメーカーによる製品保証等は適用されません。3. パッケージや、説明書等は、英語表記となります。
