Polylok Pop Up Emitter w/ 4 in. Elbow

The Polylok Flow Gate Polypropylene Green, White is an amazing product that can help you discharge excess water out of your drains without any hassle. When the pressure of water flowing through the drainage system exceeds the emitter’s hydrostatic capacity, it opens to let out that extra water. It also acts as a great deterrent against rats and debris to prevent clogging.
