Drip Irrigation Emitters: Drip Emitters are commonly inserted directly into a solid drip line which is placed close to the root zone of the plant. Emitters can also be installed at the end of a 1/4″ strand of tubing if the plant medium is a distance away from the distribution line. There is no right or wrong way to install an emitter as all methods will provide the same result. Drip Emitters are offered as both Pressure Compensated or Non-Pressure Compensated and are rated for different flow rates in either Gallons per Hour, or Litres per Hour.
