What is LayFlat
LayFlat (lay-flat, flat hose) is a fire-type hose made of polyethylene or PVC with textile reinforcement. Without pressure, it lies flat and coils into a compact roll. Under pressure, it straightens into a round tube.
The most common application is as a mainline hose for drip irrigation in home gardens and small farms.
LayFlat advantages over rigid HDPE pipe
- Compact storage: 100 m of hose in a roll takes up 3–5× less space than 100 m of HDPE pipe
- Quick installation: unrolls by hand; no welding like PPR or special fittings like HDPE
- Lightweight: 100 m of 20 mm LayFlat = ~6 kg; 100 m of 25 mm HDPE = ~15 kg. One person easily carries a roll
- Affordable: 1.5–2× cheaper per meter than HDPE
- Seasonal use: easy to remove for winter and store indoors
- Simple repairs: if damaged, cut out the defective section and join with a coupling in 5 min
LayFlat limitations
- Operating pressure: 4–6 bar maximum for standard models. Heavy duty — up to 10 bar, but more expensive
- Not for underground installation: thin walls are vulnerable to roots, rocks, and rodents. HDPE/PPR is better for burying
- Puncture-sensitive: sharp objects, machinery, and rodents can cause damage
- UV degradation: without stabilizers — 1–2 seasons in the sun. Look for UV-stabilized models
- Water hammer risk: suddenly closing a valve at high flow = burst. Use slow-closing valves
- Cannot be used as a portable hose: stationary mainline only. For hand watering, use PVC or rubber
LayFlat sizes and pressure
| Діаметр | Max. flow | Operating pressure | Application |
|---|---|---|---|
| 16 мм (1/2") | 0.5-1 м³/год | 6 бар | Home garden up to 300 m², 5–10 beds |
| 20 мм (3/4") | 1-2 м³/год | 6 бар | Home garden 300–600 m², 10–20 beds |
| 25 мм (1") | 2-4 м³/год | 5 бар | Property 600–1,500 m² |
| 32 мм (1 1/4") | 4-6 м³/год | 4 бар | Small farms up to 0.5 ha |
| 50 мм Heavy Duty | 8-15 м³/год | 8 бар | Commercial systems, fire use |
When to choose LayFlat vs. HDPE/PVC
LayFlat — best choice for:
- Seasonal garden irrigation
- Surface drip irrigation mainline
- Temporary water supply
- Small farms up to 0.5 ha with low pressure
- Locations requiring frequent disassembly
HDPE/PPR/PVC — better for:
- Underground installation
- Permanent stationary mainline
- Pressure > 6 bar
- Farms > 1 ha
- Residential water supply
- High-temperature systems
Usage tips
- On first unrolling, let water flow slowly — sudden pressure can deform the seam
- After the season, drain water, dry in shade (2–3 hours), coil into a roll 30–50 cm in diameter
- For connections — use dedicated LayFlat clamp fittings or fittings with rubber gaskets
- Repair punctures with a coupling or dedicated LayFlat tape (Tiger Tape)
- Store in a dry, warm space during winter, NOT in an unheated shed
