1. Punctures and Tears: Top Issue for Outdoor Layflat Hoses
Layflat hoses often get punctured or torn during irrigation use. Sharp objects like rocks, sticks, or farm equipment easily pierce the hose’s surface—especially thinner PVC layflat hoses. Dragging the layflat hose across rough terrain (instead of lifting it) makes this problem worse. Small punctures start as slow leaks but grow over time, wasting water and reducing pressure. For polyurethane or reinforced layflat hoses, tears usually happen at weak points like seams or old creases.
2. UV Degradation: Fades and Weakens Layflat Hoses
Constant sun exposure damages layflat hoses over time. UV rays break down the hose’s material—PVC layflat hoses turn brittle and fade, while polyurethane ones lose flexibility. A degraded layflat hose cracks easily when rolled or bent, even during light use. This problem speeds up in hot climates; a layflat hose left uncovered in direct sun may only last 6–12 months. Signs of UV damage include discoloration, stiff texture, and small surface cracks.
3. Kinking and Blockages: Disrupt Flow in Layflat Hoses
Layflat hoses kink when folded too tightly or stepped on, blocking water flow. Kinks are more common with lightweight PVC layflat hoses, as they lack the rigidity to bounce back. Over time, repeated kinking weakens the hose’s structure, leading to splits. Blockages also occur when dirt, debris, or algae build up inside the layflat hose—this happens if the hose is stored wet or used with dirty water. A blocked layflat hose causes low pressure or uneven irrigation.
4. Pressure Overload: Bursts Layflat Hoses
Using a layflat hose beyond its pressure rating causes bursts. For example, a standard PVC layflat hose (rated 80 PSI) will burst if connected to a high-powered pump that pushes 120 PSI. Bursts usually happen suddenly, spraying water and damaging the hose beyond repair. Reinforced layflat hoses resist this better, but they still fail if pressure spikes (e.g., from a stuck valve). Always check the layflat hose’s pressure label before connecting it to a system.
