This dripperline features 1.0 GPH pressure-compensating (PC) emitters spaced evenly 18 in. apart throughout the entire run. PC emitters maintain a steady output of water even if the water pressure were to change. The self-cleaning emitters flushes out sediments that can lead to clogging. Tubing is made of polyethylene, and emitters are made of polyethylene and silicone, all treated with UV inhibitors.
