They are flexible, lightweight, affordable, strong under pressure, and engineered for the rugged life of fields, pumps, and daily coil-and-uncoil cycles.
This guide brings a complete explanation of what PVC lay flat water discharge hoses are, why farmers prefer them, how to select the correct size and pressure rating, expected pricing, technical specifications, maintenance tips, and expert-level guidance for long-term performance in agricultural irrigation.
Whether you’re sourcing for a farm, a wholesale business, a local dealership, or a global B2B project, this article lays out everything needed to make a confident, well-informed purchase.
1. What Is a PVC Lay Flat Water Discharge Pump Hose?
A PVC Lay Flat Water Discharge Pump Hose is a flexible, collapsible hose made of polyvinyl chloride (PVC) reinforced with polyester yarn. When not in use, it collapses into a flat shape—hence the name “lay flat”—making it easy to store and transport. When water pressure flows through it, the hose expands into a round tube.
It is commonly used with:
• Water pumps
• Agricultural irrigation systems
• Flood control & drainage
• Construction dewatering
• Sprinkler and drip systems
• Rural water supply lines
On farms, this hose is famous for one ability above all others: moving large amounts of water quickly and reliably.
2. Why PVC Lay Flat Hose Is Perfect for Agricultural Irrigation
Agriculture is a physically demanding environment. Hoses must endure sun exposure, dragging on gravel, sudden pressure spikes from pumps, and long-term contact with soil and fertilizers. PVC lay flat hose has earned its reputation because it simply performs.
Here’s why farmers appreciate it:
2.1 Lightweight but Strong
Even long hoses—50m, 100m, and 200m rolls—are manageable by one or two people. That’s critical for field work where distance is measured in acres, not meters.
2.2 Resistant to Sun & Weather
High-quality hoses include UV stabilizers that prevent cracking or fading under harsh sunlight.
2.3 High Pressure Endurance
Different pressure ratings (2-10 bar and higher) handle everything from small irrigation pumps to industrial water transfer.
2.4 Easy to Move, Install & Store
When the workday ends, it rolls up flat and takes up very little space.
2.5 Compatible with Many Water Pump Types
Diesel pumps, electric pumps, PTO pumps, and solar-powered pumps all pair well with lay flat hoses.
2.6 Affordable and Long-Lasting
Compared with rubber hose or rigid PVC pipe, the cost-to-performance ratio is extremely attractive.
When a solution blends durability, simplicity, and affordability, farmers tend to adopt it quickly—and PVC lay flat hose has become a global favorite.
3. Key Features of PVC Lay Flat Water Discharge Pump Hose
To choose the right hose, buyers need to understand the technical features that determine its performance.
3.1 PVC Material Quality
High-grade hoses use:
• Virgin PVC (not recycled)
• Anti-aging formula
• UV resistance
• Softening agents to maintain flexibility
• Chemical-resistant additives
Better ingredients mean longer lifespan.
3.2 Reinforcement Yarn
A polyester woven jacket gives tensile strength and prevents the hose from bursting. The density and weave angle influence pressure rating and durability.
3.3 Inner & Outer Wall Thickness
Thicker walls resist abrasion from soil and pump vibration.
Typical hose wall thickness ranges from 1.3 mm to 3.5 mm, depending on pressure rating.
3.4 Burst Pressure & Working Pressure
Agricultural hoses generally offer:
• 2–4 bar for low-pressure irrigation
• 4–6 bar for pump discharge
• 8–10 bar for high-pressure applications
A safe burst pressure is three times the working pressure.
3.5 Temperature Resistance
PVC lay flat hoses usually work within:
−5°C to +65°C
Summer heat and mild frost are fine, though winter freezing must be avoided.
3.6 Hose Color
Color indicates grade:
• Blue – Standard irrigation hose
• Green – Premium reinforced irrigation hose
• Yellow/Orange – Construction-grade high-strength hose
• Red – Heavy duty, high-pressure hose
• Transparent blue – Lightweight economical hose
Color coding helps farmers sort hoses at a glance.

6. Applications in Agricultural Irrigation
PVC lay flat hoses are “multi-tool” components in irrigation. They connect pumps, distribute water, and support different irrigation styles.
6.1 Pump Discharge
This is the primary purpose. A diesel or electric pump pushes water through the hose to:
• water tanks
• canals
• drip systems
• sprinkler systems
• furrow irrigation
• overhead irrigation systems
6.2 Flood Irrigation
Still widely used in rice fields, vegetable farms, and orchards.
6.3 Drip Irrigation Lines
Mainlines often use 2"–4" lay flat hose, feeding smaller drip lines.
6.4 Traveling Sprinklers and Boom Irrigation
Large farms use lay flat hoses with big reel systems that require flexible water supply lines.
6.5 Water Transfer Between Ponds & Tanks
Pump water from reservoir → farm → fields → drainage areas.
6.6 Fertilizer and Nutrient Delivery
Most PVC hoses resist common fertilizers and diluted chemicals.
Farmers appreciate tools that endure mud, roots, rocks, and long seasons—and PVC lay flat hoses excel in this tough environment.
7. How to Choose the Right Hose for Your Farm
Choosing the wrong hose size can limit pump performance. Here’s the practical approach farmers use.
Step 1: Match Hose Diameter to Pump Outlet
If a pump has a 3" output, use a 3" hose. Undersized hoses choke pump flow.
Step 2: Select the Correct Pressure Rating
Use:
• 2–4 bar for low-pressure drip systems
• 4–6 bar for pump discharge
• 8–10 bar for industrial pumps or long-distance water transfer
Step 3: Consider Length Requirements
Longer hoses increase friction. High-power pumps need higher pressure-rated hoses.
Step 4: Check the Reinforcement Quality
Dense polyester braiding improves lifespan.
Step 5: Confirm Connection Types
Camlock connectors are the most common for farm pumps.
Step 6: Evaluate Sun Exposure
If the hose sits in open sun daily, UV-resistant grades are essential.
As irrigation systems grow more sophisticated, simple mistakes like using the wrong hose diameter can slow down an entire farm’s output.
