How to Install Simple Drip Irrigation
A basic drip irrigation system is easier to install than it looks.
For a small garden, you can build one with a few simple parts.
What You Need
A basic system may include:
- Hose faucet
- Backflow preventer
- Filter
- Pressure regulator
- Mainline tubing
- Drip tubing or emitters
- Connectors
- End caps
- Timer
Step 1: Plan the Layout
Sketch:
- Faucet location
- Beds
- Rows
- Fruit trees
- Mainline path
Keep the system as simple as possible.
Step 2: Connect to the Faucet
A typical order is:
- Faucet
- Backflow preventer
- Filter
- Pressure regulator
- Timer, depending on setup
- Mainline tubing
Follow the manufacturer’s instructions.
Step 3: Run the Mainline
Run larger tubing along:
- Bed edges
- Paths
- Fence lines
Avoid placing it where it will be stepped on or hit by equipment.
Step 4: Add Drip Lines
Run drip tubing through each bed.
For raised beds, parallel lines often work well.
Spacing depends on:
- Soil type
- Plant spacing
- Emitter spacing
Step 5: Secure the Tubing
Use landscape stakes to hold tubing in place.
Step 6: Flush the System
Before closing the ends:
- Turn on the water.
- Flush dirt and debris.
- Close the line.
Step 7: Test
Check for:
- Leaks
- Clogged emitters
- Uneven pressure
- Dry areas
Step 8: Add a Timer
Timers make regular watering much easier.
But do not set it once and forget it.
Adjust for:
- Rain
- Temperature
- Season
- Crop size
How Long Should It Run?
That depends on emitter flow rate and soil.
Measure actual output rather than guessing.
Mulch Over Drip Lines
Drip tubing can usually sit under mulch.
This reduces evaporation and protects tubing from sun exposure.
GardenGrowz Tip
Install irrigation before the garden is full of mature plants.
It is much easier to lay tubing when you can still see the soil.
