how to use

R750 Adjustable Micro Sprayer Kit


The R750 Adjustable Micro Sprayer Kit with six micro sprayers with adjustable stakes and two vortex umbrella-pattern sprayers can be used in a wide range of layouts for watering shrubs, groundcovers, flowerbeds and under trees canopy. The kit uses adjustable stakes with micro sprayers with a full circle pattern or 360°, 180° and 90° to provide full flexibility within the installation. The micro sprayers used in this kit have no moving parts and distribute the water in a very similar manner to conventional spray heads but with very low flow or with very low application rate. This kit is a complete kit containing all the parts required to install a complete system. This kit can be connected into a 3/4” hose garden or faucet/spigot and we highly recommend installing the 25 PSI pressure regulator (included in this box) after the backflow preventer. The pressure regulator is used to lower the incoming pressure of the system to the suggested operating pressure of 25 PSI, which is within the range of recommended pressures for drip irrigation or micro sprinkler systems. Please make sure to add this device after the backflow preventer. The instruction manual for this kit can found in the kit package

Installation Steps


Connect to your water source using the backflow preventer, pressure regulator and swivel tubing adapter.


Lay the poly tubing in and around plants using compression elbows and tees as needed. Leave the poly tubing out in the sun for a few minutes to make it easier to work with.


Assemble your adjustable micro sprays.


Where you would like to place a micro spray, punch a hole in the poly tubing using the hole punch.


Connect micro sprayers to the 1/2” poly tubing using the included precut lengths of micro tubing.


Flush the line and close the end of the poly tubing using a figure “8” hose end.

Example layout:


Start the kit from a faucet or garden hose

  1. The basic installation recommendation for this type of kit is first to review the area and then to make a drawing of the garden or site with your preferred layout.
  2. In the installation stage, to the faucet, first connect the backflow device, then the 25 PSI pressure regulator and then the 3/4" swivel adapter with screen. If water quality is a concern, we highly recommend using our fine mesh 3/4" filter with 155-mesh (model D57A not included with this kit).
  3. Connect the 1/2" drip tubing to the swivel adapter by forcing and wiggling the drip tubing into the compression side of the adapter. Lay the 1/2" drip tubing per your drawing and secure the drip tubing to the ground using the stakes provided.
  4. Add fittings such as tees per your drawing layout, leaving the end of the drip tubing open.
  5. Turn the faucet on to flush the line. Then shut off the faucet and close the end of the drip tubing using the hose end included with the kit.
  6. Install the adjustable stakes every five to seven feet for full coverage, or as needed, and about two to six inches from the path of the drip tubing. a. Near each adjustable stake, punch a hole into the side of the 1/2" drip tubing and insert the barb at the end of the micro tubing assembly into the drip tubing. b. Insert the other end of the micro tubing into the adjustable stake. c. Thread the poly riser into the adjustable stake. d. Thread the micro sprayer into the poly riser.
  7. Turn the water on and adjust the flow on each stake as needed.
  8. To automate the system, install one of our hose-end timers after the backflow device.

Note: To expand the kit we highly recommend continuing with the same model micro sprayers and the same components.
Review the instruction manual included with the kit for complete details.

Drip Fitting Installation Recommendations:

Our drip fittings are compression type which hold the drip tubing with a sharp edge over the outside diameter of the tubing. While it may seem hard to install, we assure you that after you install it you will not have any problems of drip tubing and fittings separating in hot weather. To connect the 1/2" compression fittings, cut the drip tubing with a hand pruner, being careful to keep dirt from entering the drip tubing. Hold the compression fitting in one hand and the drip tubing in the other and force the drip tubing into the fitting by wiggling it from side to side. Make sure that the drip tubing is pushed into the compression fitting for about 1/2" to 5/8" for a very tight fit. No glue or clamps are required.

About the soil and suggested watering time:
* Sandy soil or light textured soil: Water percolates straight through before it can spread far enough horizontally, so apply water at close intervals such as every other day for 20 to 90 minutes depending on plant size and type, daylight conditions (full sun, partial sun or shaded) and weather pattern (cold to hot) with the plants under full sun in hot conditions getting the longer period.

  • Loamy soil or medium textured soil: This is the ideal soil condition with water moving slowly and spreading evenly, so apply water at wider intervals such as every two to four days for 15 to 90 minutes depending on plant size, type, daylight conditions (full sun, partial sun or shaded) and weather pattern (cold to hot) with the plants under full sun in hot conditions getting the longer period.

  • Clay soil or heavy textured soil: Water is absorbed very slowly, so apply water at longer intervals such as every three to five days for 30 to 60 minutes depending on flow rate, plant size and type, daylight conditions (full sun, partial sun or shaded) and weather pattern (cold to hot) with the plants under full sun in hot condition getting the longer period.
