Drip Irrigation - Part 4: Using Emitterline in the Garden

Welcome to part 4 of our series on assembling a drip irrigation system. We're sharing tips on how to install emitterline. Before getting started, we recommend watching Part 1: How to Assemble a Drip Irrigation System. You can also watch our video on installing emitterline, where Tricia demonstrates its use in the garden.

Facts About Emitterline

Best operating pressure is between 6 psi and 15 psi.
Emitterline is ideal for meandering lines in garden beds or landscaping areas.
Perfect for moderate water coverage for shrubs, perennials, trees, and garden beds.
It is available in 1/4" and 1/2" sizes.
1/2" emitterline has 1.0 GPH emitters spaced every 12" with a maximum run length of 216 feet at 25 psi and 357 feet at 55 psi.
1/4" emitterline has 0.5 GPH emitters spaced every 6" with a maximum run length of 18 feet.

Installing 1/2" Emitterline in Straight Lines

Extend your 1/2" poly tubing along one full edge of the garden.
At desired branching points, cut the poly tubing and insert a Power-Loc 1/2" Tee. Reconnect the tubing and ensure the third end faces the direction of the emitterline.
At the end of the emitterline, install an End Cap or fold over the end using a 1/2" Figure 8 Closure.
Use elbows to make sharp turns and prevent kinks.
Ensure emitterline holes face up when laying it down.
Secure the emitterline with ground staples.
