Parts and How It Works
Main System Parts
Take a look at your garden layout as we break down the essential components and their functions.
A drip irrigation system uses several parts to ensure water reaches your plants efficiently:
- Backflow preventer: Keeps your drinking water supply safe from contamination.
- Filter: Removes debris and particles that could clog the system.
- Pressure regulator: Adjusts the water pressure for proper drip system operation.
- Mainline tubing: Transports water throughout the system.
- Emitters or microtubing: Delivers water directly to the root zone of each plant.
System Operation
Here’s how it works: water flows through the backflow preventer, then passes through the filter and pressure regulator before entering the mainline tubing. From there, the water moves to the emitters, which release it at a steady, controlled rate right at the plant roots. The system operates at a lower pressure than standard garden hoses, reducing overspray and evaporation. Running it during the cooler early morning hours helps conserve even more water.
Once you understand these components, you’re ready to plan your layout and choose the right parts in the next section.
Planning Your System
Garden Requirements
Start by sketching out your garden. Include the beds, pathways, and water connections. Here’s what you need to note:
- Garden size: Measure the total length and width.
- Water source distance: Determine how far the water source is for tubing placement.
- Water pressure: Measure the pressure at your faucet.
- Soil type: Identify if it’s sandy, loamy, or clay.
Group your plants based on their water needs. For example, place plants that need more water in one area and drought-tolerant ones in another. This will help you select the right emitters and flow rates.
Selecting Parts
With your garden map and plant groupings ready, pick components that fit your layout and watering needs:
- Mainline tubing: Use UV-resistant polyethylene tubing, sized for your longest runs.
- Emitters: Match flow rates to plant groups. For sloped areas, use pressure-compensating emitters.
- Fittings: Stock up on tees, couplers, end caps, goof plugs, and stakes. It’s smart to have around 10% extra tubing and fittings for adjustments or repairs.
Once you’ve gathered everything, follow the step-by-step setup instructions to install your system.

- Test water pressure and flow: Every 2–3 months, check these to ensure water is being delivered evenly.
- Update timer settings: Adjust seasonally based on your plants’ watering needs.
Preparing for Weather Changes
- Winterize before freezing temperatures: Drain and disconnect the system when frost is expected (below 32°F). Use insulation covers on exposed parts.
- Spring cleaning: Flush the system thoroughly before starting regular use.
- Adapt to weather conditions: Adjust the watering schedule based on rainfall and temperature forecasts.
Troubleshooting Common Issues
- Clogged emitters: Remove them and soak in a vinegar solution, or replace if necessary.
- Low water pressure:
- Look for kinked tubing.
- Clean the system’s filter.
- Check the pressure regulator settings.
- Uneven watering:
- Make sure emitters aren’t blocked by mulch or soil.
- Verify proper spacing between emitters.
- Replace any damaged tubing sections.
