EF55AS Micro Sprinkler Watering Kit

DIG's Micro Sprinkler Kit is a complete kit that includes all the parts needed to install a micro sprinkler system to water flowerbeds, ground covers and under fruit tree canopies. The kit covers up to up to 250 sq ft and can be expanded to cover more than 750 sq ft using additional drip tubing, micro sprinklers, and stakes or additional kits. This full circle micro sprinkler's flow rate is 21-GPH using a "G" bridge with a spinner to cover up to a 26' diameter @ 25 PSI. The micro sprinkler has additional inserts that allow for 90°, 180° and strip patterns with up to a 12' diameter. The kit also includes two small-diameter spray jets on 10/32 thread with inserts for 90° and 180°, used for small diameter areas. This kit contains all the parts needed to install a system from a faucet or a garden hose including a 3/4" backflow preventer, 3/4" 25 PSI pressure regulator, 3/4" swivel adapter, 50' of our premium 1/2" drip tubing with .700 OD, five large diameter micro sprinklers, three small diameter micro sprayers, and all the necessary parts to complete the installation.

Features

About

The EF55AS Micro Sprinkler Kit includes five completely assembled 21-GPH micro sprinklers and two micro sprayers with threads that can be used in a wide range of layouts for watering shrubs, groundcovers, vegetables, flowerbeds and under tree canopies.

The kit uses micro sprinklers with a full circle pattern, or 360°, and interchangeable sprayer inserts to replace the spinner. This bridge type micro sprinkler operates using a spinner, which is seated on top of the nozzle or orifice and secured by the bridge design. When water passes through the green nozzle it spins the spinner, which throws the water in a full circle to the diameter determined by the spinner design, the flow rate and the pressure. The micro sprinkler spinner is mounted within the "G" type bridge and it is secured by the nozzle. The spinner can be replaced by removing the nozzle, first turning the nozzle assembly clockwise and then removing the spinner. The spreader is used by inserting the pin side of the spreader into the G-shaped Bridge. The 180°, 90° and strip pattern spreader inserts provide full flexibility within the installation. The kit also includes three small-diameter 360° jet sprayers that can cover up to a 5' diameter with a deflector tip for 90°, and 180°.

This is a complete kit containing all the parts required to install a complete system from a 3/4" hose garden or faucet/spigot. 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.

Installation Steps

EF55AS-step-1

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

EF55AS-step-2

Lay the poly tubing in and around plants. Leave the poly tubing out in the sun for a few minutes to make it easier to work with.

EF55AS-step-3

Connect compression elbows and tees as needed.

EF55AS-step-4

Secure the line using tubing stakes.

EF55AS-step-5

Where you would like to place a micro spray, punch a hole in the poly tubing using the hole punch, insert the barbed end of the micro tubing and secure the micro spray into the ground.

EF55AS-step-6

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


Example layout:

EF55AS-example-layout

Start the kit from a faucet or garden hose

  1. First review the area to be irrigated and then make a drawing of the garden or site with your preferred layout.
  2. To automate the system, install one of our hose-end timers (not included) after the backflow device.
  3. In the installation stage, to the faucet, first connect the backflow device, then the pressure regulator and then the 3/4" swivel adapter with the 60 mesh 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.
  4. Lay the drip tubing per your drawing and secure the drip tubing to the ground using the stakes provided.
  5. Add fittings such as elbows and tees per your drawing layout, leaving the end of the drip tubing open.

    a. To install the 1/2" compression fittings, cut the drip tubing with a hand pruner, being careful to keep dirt from entering the line. 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
    b. Near each micro sprinkler, 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.

  6. Install the micro sprinklers on spikes every 12 to 16 feet for full coverage, or as needed, and about two to six inches from the path of the drip tubing. Make sure that the micro sprinkler assembly on a stake is mounted seven to eight inches above ground.

  7. The spray jet can be threaded directly into the drip tubing by punching a hole on the upper side of the drip tubing.

  8. Turn the faucet on and flush the line for a few minutes to clean all debris that may be trapped inside the drip tubing. Then shut off the faucet and close the end of the 1/2” drip tubing using the 1/2” hose end included with the kit.

  9. Pressurize the system again, adjust the micro sprinklers assembly height if needed and make sure that the system is working correctly and no leak appears.

Note: To expand the kit we highly recommend continuing with the same model micro sprinklers 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 that hold the drip tubing with a sharp edge over the outside diameter of the tubing. While they may seem hard to install, we assure you that after you install them 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.
