When using this type of adjustable drip emitter be aware that as you adjust the flow, the total flow rate of the system may be affected and this may lower the system uniformity.  In other words, increasing the flow from each adjustable drip emitter on your system may limit the efficiency of the system.

Retrofitting a conventional spray head into a low flow, water saving drip irrigation system requires a few simple steps:

Step 1: Evaluate the areas to be watered. While large areas such as lawns are best watered by sprinklers, other areas, such as shrubs, roses, or individual plants, can be irrigated more efficiently by using an adjustable drip emitter on ½” FNPT.

Step 2: Remove the spray head from the ½” riser.

Step 3: Turn the water on and flush the line.

Step 4: Screw the adjustable drip emitter on ½” FNPT onto the riser.

Step 5: Turn the water on and adjust the flow and diameter as needed
