Installing a Drip Irrigation System

 
Drip irrigation is an efficient, easy to design and install permanent irrigation system. Drip irrigation works by applying water slowly, directly to the soil and plants. Kits for drip irrigation are inexpensive and assembly is straightforward. You can install one in as little as one day's time, and few tools are required.

WHAT YOU NEED FOR THIS JOB:

TOOLS:

MATERIALS:


Step 1: Lay out a grid with hoses and emitters showing the plants you want to water and how far apart they are Planning the irrigation system

 Planning the Irrigation System

• Each plant will get an emitter, a tiny sprinkler for its own watering needs and each 
  will be attached to the water source with a network of drip irrigation lines, 1/4 and 
  1/8-inch plastic tubing that runs from the main hose to your plants.For continuous 
  coverage, place emitters every 12-inches apart in sandy soil, 18-inches in loamy 
  soil and 24-inches in clay soil.

  

Step 2: Assembling the hoses

Assembling the Hoses

• Install a backflow preventer valve to the outdoor faucet to keep groundwater from 
  backing up into your drinking water.
 

• Attach a hose adaptor to fit the diameter of the system's main line.
 

• Connect the system's main line to the backflow preventer and run it to the garden. 

  

Step 3: Install T’s for branch lines

Install T’s for Branch Lines

 • Place a T in the line for each branch line and secure with band clamps.
 

 • Cut lengths of line long enough to extend through the garden to each T.

  

Step 4: Install emitters and feeder lines

Install Emitters and Feeder Lines

• Punch holes in the line for each emitter with emitter tool and place emitters in the 
  desired location.
 

• If plants to be irrigated are more than 1-foot away from the line, cut an appropriate 
  length of 1/8-inch emitter tubing and attach the feeder line to the emitter on the 
  branch line and then attach an emitter to the end of the feeder line.
 

• Plug the ends of the individual lines with caps and secure with band clamps.
 

• Flush the system every 4 to 6 months by removing the end caps and turning on 
  the water, allowing it to run until the water flows clear.
