The Pop Up Emitter is an easy, safe and effective answer to any drainage need. The Pop Up Emitter diverts and releases water away from all types of structures; landscapes where erosion is common and very poor drainage areas that you may encounter.
Fits 3" & 4" drainage pipe and corrugated downspout.
The design of this product allows the Pop Up Emitter to open with a small amount of pressure. It will close during dry weather so that debris and animals will not be able to enter the drainpipes. The pressure of water coursing through the drainpipe opens the Pop Up Emitter; it will close as the water flow decreases.
