Facts About Emitterline
- Best operating pressure is between 60 psi and 15 psi.
- The emitter line is great for areas that you want to water with a meandering line.
- It's good for moderate water coverage in landscaping areas such as shrubs, perennials, trees and it can also be used for garden beds.
- Emitterline is sometimes confused at first glance with poly tubing.
- It comes in 1/4" and 1/2".
- 1/2" emitterline has 1.0 GPH emitters spaced every 12". At 25 psi the maximum run length is 216 feet, at 55 psi, the maximum run length is 357 feet.
- 1/4" emitterline has 0.5 GPH emitters spaced every 6". The maximum run length is 18 feet.
Installing 1/2" Emitterline In Straight Lines
- Extend your 1/2" poly tubing (supply line) along one full edge of the garden.
- At the spots where you want to branch off an emitterline, cut the poly tubing and insert a Power-Loc 1/2"Tee, reconnect the poly tubing and the third end is facing in the direction of your emitterline.
- At the end of the emitterline install an End Cap, an End Cap with a Flushable Valve or just fold over the end and use a 1/2" Figure 8 Closure.
- If you need to make any sharp turns, use an elbow, to prevent kinking.
- Make sure the holes are facing up when laying the emitterline down.
- Secure it with ground staples.
