A French drain is only as good as its outlet, and Rain Bird's pop-up emitter is the industry standard for terminating drain systems cleanly and preventing backflow. This complete kit includes 50 feet of 4-inch corrugated perforated pipe with a pre-installed filter sock, a Rain Bird 100 pop-up emitter, two NDS reducers, and all needed couplings and end caps. The pop-up emitter opens automatically when water flows and closes when dry — keeping small animals, insects, and debris out of the pipe when not in use, while eliminating the pooling that happens with open-ended pipes. Installs in under 3 hours for a typical single-downspout drainage project. Rain Bird is the most trusted name in irrigation and drainage, used by landscape professionals in more than 130 countries.
