Rainforest Sprinklers will save up to 1/3 less water than many other sprinklers. Great for low pressure systems and powerful enough for up to 6 sprinklers in sequence. Rainforest Ecological Sprinklers will not clog and have very few moving parts. Adjustable at the tap from 6-50ft. in diameter. Rainforest Ecological Sprinklers emit a rain/mist spray, allowing for maximum saturation with minimal water usage. Truly a remarkable water saving sprinkler system.
