  • Demonstration Connecting a Micro Sprayer to .700 Poly Tubing


The model 9802-2 (pack of two) Spray Stick is available with a 160° circle spray pattern and a flow rate of 5.4 to 7.2 GPH at 15 to 25 PSI. It has spray coverage of about 10″ to 12″ and can fit small planter boxes, pots, baskets or containers. The water flow is controlled at the stick’s outlet, where it matters most. Each assembly includes a 5” long spray stick, 24” of 1/8” micro tubing and an 1/8” x 1/4” barb to connect the micro tubing to the drip tubing. Use the spray stick where overhead watering is suggested, including vegetation that requires higher moisture content. Made from premium UV-resistant resins, which resist tip damage, the stick provides years of trouble-free operation in both indoor and outdoor applications.

For complete coverage of an area, the recommended spacing is one spray stick per plant to a maximum distance of 52′ to 84’ in length using 1/2” drip tubing as the main lateral. Like micro sprayers, the spray stick operates at low pressure and requires a filter to protect the water passages of the sprayer. The main advantages of using the spray stick are that a relatively large number can operate simultaneously with a small sized pipe, and the assembly has no moving parts.

Installation suggestions

Basic installation recommendations for this product include first reviewing the area and then making a drawing of the garden or site with your preferred layout.
If automation is required, use one of DIG’s hose end timers or battery operated controllers. The ideal controller should have flexible scheduling and two to four start times per day for added flexibility.

Product installation

  1. Using the drip tubing as the main lateral or as a sub lateral, lay out the drip tubing per your layout drawing. Secure the drip tubing to the ground using stakes (model R60) in key areas and add more stakes as you unroll the drip tubing. Add stakes every 20′-30’ and at the end of each section, or as needed. An extra 1% of drip tubing length should be added to each lateral to compensate for contraction at low temperature.
  2. Throughout the installation and per your drawing layout, add, if needed, 1/2” fittings, such as tees (model C35) and elbows (model C36), leaving the end of the drip tubing open. To install the 1/2″ compression drip fittings, cut the drip tubing with a hand pruner, being careful to keep dirt from entering the line. Hold the fitting in one hand and the drip tubing in the other and force the drip tubing into the compression fitting by wiggling it from side to side.
  3. The spray sticks are installed along the drip tubing at varying or at specific intervals, or one per pot or basket. The distribution uniformity of water from the spray sticks along the line depends on the incoming pressure, number of spray sticks used per lateral and the length of the laterals. Special care should be taken to ensure high uniformity of water along the laterals by not exceeding the product recommendations (see chart).
  4. To install the spray stick, punch a hole into the drip tubing using the small punch (model D44) or the gun punch (model 16-035) and snap the 1/4” barb at the end of the micro tubing into the drip tubing.
  5. Insert the spray stick into the pot or basket, six to eight inches from the plant.
  6. Turn the water on and flush the line.
  7. Close the end of the drip tubing using the hose end (model Q58) or figure “8” (model F68B).
  8. Pressure-test the system to identify leaks in the drip tubing laterals, fittings and micro tubing, and then program the hose end timer or battery operated controller.
