A quick guide to deploying your sprayers.

Step 1: Connect to Micro Tubing
Push the barbed end of the Teco Down Spray Assembly directly into a length of 1/4" micro tubing. The tubing will seat securely over the barb without the need for glue.

Step 2: Mount on a Stake
To keep the sprayer elevated and prevent it from dragging in the dirt, clip the assembly onto a rigid plastic or metal drip irrigation stake positioned near the base of your plant.

Step 3: Connect to Mainline
Use a punch tool to create a hole in your 1/2" or 3/4" poly mainline. Insert a 1/4" transfer barb into the hole, and attach the other end of your micro tubing to the barb.

Step 4: Operate the Shut-Off Clip
If you need to stop watering a specific plant, simply slide the small plastic shut-off clip down over the micro tubing just below the sprayer to securely pinch off the water flow.

How does the downward spray pattern of the Teco Down Spray 45° PC help during hot summer days?
The targeted 45-degree downward angle keeps the water stream low to the ground. This drastically reduces wind drift and mid-air evaporation during summer heat waves, ensuring more water reaches your plant's root zone.

Traditional micro-sprinklers that spray upward can lose a significant amount of water to the hot summer air before it even hits the soil. Downward sprayers maximize watering efficiency.

What is the purpose of the shut-off clip on the Teco Down Spray 45° PC?
The built-in shut-off clip allows you to instantly stop water flow to an individual emitter without removing it from the line. This is ideal when rotating crops, harvesting early, or removing a dead plant.

Instead of plugging the mainline hole or removing the 1/4" tubing entirely, you can just pinch the line shut until you are ready to put a new plant in that location.

Are the Teco Down Spray 45° PC emitters pressure compensating?
Yes, these emitters feature a pressure-compensating diaphragm. This ensures that every Teco Down Spray on your line delivers the exact same amount of water, regardless of elevation changes or distance from the water source.

Pressure compensation is highly recommended if your garden is planted on a hillside or if you are running exceptionally long lateral lines, as it prevents the plants at the end of the line from being underwatered.

How do I connect the Teco Down Spray 45° PC to my irrigation system?
This assembly is designed to push directly into standard 1/4-inch micro tubing. You can then route that micro tubing back to a 1/2-inch poly mainline, securing the spray jet near your plant using a stake.

Because these output higher flow rates (10.5 to 20.5 GPH), be sure to calculate your total zone flow to ensure your mainline can supply enough water to run all of your sprayers simultaneously.
