Drip Irrigation Tape Buyer’s Guide

Drip irrigation tape is one of the most efficient and precise irrigation solutions for crops of all sizes. It delivers water directly to plant roots, reduces waste, and allows controlled application of fertilizers. This guide helps growers understand how to choose, install, and maintain drip tape for optimal performance.

1. What is Drip Irrigation Tape?

Drip tape is a thin-walled polyethylene tubing with built-in emitters that release water at a controlled rate directly to the root zone. Unlike traditional hoses or sprinklers, drip tape provides steady, slow irrigation, reducing water loss from evaporation and runoff.

Key characteristics:

Lightweight and easy to handle

• Can be used above-ground, buried (subsurface), or under mulch

• Operates at low pressure (usually ≤15 PSI)

• Compatible with fertigation systems to apply nutrients

Applications: Row crops, orchards, vineyards, vegetables, strawberries, lettuce, onions, garlic, and more.

2. Key Factors When Selecting Drip Tape

Choosing the right drip tape involves four major considerations: diameter, wall thickness, emitter spacing, and flow rate. Each factor impacts water efficiency, crop health, and tape longevity.

2.1 Diameter

Drip tape diameters typically range from:

• 5/8" – Best for gardens and small farms (short rows ≤600 ft)

• 7/8" – Medium-scale farms with moderate row length

• 1 1/8" & 1 3/8" – Large-scale commercial farms with long rows

Tip: For most small-to-medium farms, 5/8" tape is sufficient, while larger farms benefit from wider diameters to maintain pressure across longer runs.

2.2 Wall Thickness

Tape wall thickness is measured in mil. Thicker walls increase durability and allow reuse:

Recommendation: Beginners and home gardeners should use 15 mil tape, as it resists damage, allows multiple seasons of use, and reduces long-term cost.

2.3 Emitter Spacing

Emitters are built into the tape at regular intervals. Common spacings include:

Tip: Choose spacing according to crop type, soil, and row layout.

2.4 Flow Rate Selection

Emitter flow rate affects water distribution and system capacity.

Considerations:

1. Run Length: Longer rows require lower-flow emitters to avoid overwatering and maintain pressure. For rows over 500 ft, low-flow emitters are recommended.

2. Soil Type:

3. Filtration: Low-flow emitters are prone to clogging. Always use a 200-mesh or finer filter. Hard water or mineral-rich water may require higher-flow emitters.

3. Design Considerations

Before purchasing drip tape, consider:

• Row length and width – Measure accurately to calculate total tape required.

• Field slope and drainage – Avoid excessive elevation changes; tape works best on gentle slopes.

• Crop water requirements – Know the daily water needs for your crop type.

• Soil texture and chemistry – Clay, loam, and sand require different emitter flow rates.

• Water source – Verify quality, availability, and pressure.

• Future expansion – Design layout for modularity so you can add rows or crops later.

4. Installation Guidelines

Proper installation ensures uniform water delivery and long tape life:

1. Pressure Regulation: Use a pressure regulator to maintain operating pressure below the maximum recommended for your tape thickness.

2. Emitter Orientation: Emitters should face upwards to reduce clogging and maximize water delivery.

3. Connection: Use adapters to connect tape to the mainline or supply tubing.

4. Flush Valves: Install at the end of each line to remove debris and winterize the system.

5. Burying Tape: Subsurface installation is optional; it protects tape from UV and reduces evaporation.

6. Mulching: Mulch can improve water retention and protect tape from sunlight and mechanical damage.

Tip: Maintain consistent row spacing and avoid sharp bends to prevent kinking.

5. Maintenance Tips

• Regular Flushing: Flush lines periodically to prevent sediment buildup.

• Filter Cleaning: Check and clean filters weekly in high-sediment water areas.

• Check Pressure: Monitor system pressure to prevent bursts or low-flow issues.

• Tape Inspection: Look for leaks, holes, or UV damage; replace damaged sections promptly.

• Reuse Tape: Retrieve thick tape (≥8 mil) at season end for storage and reuse.

6. Benefits of Drip Tape Irrigation

• Precision watering – Water is delivered exactly where needed.

• Water savings – Up to 50% less water than traditional sprinklers.

• Reduced labor – Automation reduces manual irrigation effort.

• Fertilizer efficiency – Supports fertigation for uniform nutrient application.

• Faster crop growth – Consistent water and nutrient delivery improves quality and yield.

• Cost-effective – Low energy requirements and long-term tape reuse offset initial costs.

7. Frequently Asked Questions

Q: Can drip tape handle curves or steep slopes?
A: Drip tape performs best in straight runs and gentle slopes; sharp bends or high elevation differences can affect water distribution.

Q: How long does drip tape last?
A: Tape lifespan depends on thickness: 4–6 mil lasts 1 season, 8–10 mil lasts 2–3 seasons, 15 mil lasts up to 10 seasons.

Q: Can drip tape be used for fertigation?
A: Yes, compatible with fertilizers and other soluble chemicals.

Q: Can drip tape be buried?
A: Yes, burying (subsurface) reduces evaporation and protects the tape. Above-ground use under mulch is also effective.

Q: How do I prevent clogging?
A: Use proper filtration, maintain flow rates suitable for your soil, and flush lines regularly.

8. Summary

Drip irrigation tape is ideal for row crops, orchards, greenhouses, and high-value vegetables. By carefully selecting diameter, wall thickness, emitter spacing, and flow rate, growers can maximize efficiency, crop quality, and water savings. With proper planning, installation, and maintenance, drip tape irrigation pays for itself quickly and supports sustainable farming.Contact us for more
