Drip emitter/Bubbler irrigation system


Drip/trickle irrigation with adjust flow rate with low pressure valve.

  Drip emitters flow at very low rates, most often 4 gallons per hour
  Bubbler: gallons per minutes

Combining bubblers with sprinklers: Normally bubblers are separated onto a valve circuit of their own so that the watering time can be fine-tuned for exactly how long it takes to flood the desired areas with water. However, a small number of bubblers with adjustable flows can usually be installed on the same valve zone with spray-type sprinklers that are watering adjacent shrubs or groundcovers. Installing bubblers on the same zone wtih spray -type sprinklers is not the most efficient way to go, but as long as it is only 2 or 3 bubblers and they are watering a very small area (not more than 3′ square per bubbler) you can generally play with the bubbler’s flow adjustments and get a reasonably workable watering balance. When watering a larger area using many bubblers or when using non-adjustable flow bubblers you should place the bubblers on a separate valve zone/circuit consisting only of bubblers. Placing bubblers on the same valve zone with rotors or drip irrigation seldom works out well. Do not combine bubblers on the same zone with lawn sprinklers.
