Installation & Maintenance Tips

Unrolling: Unroll the hose from the outside of the coil, laying it flat on the ground. Never drag the coil laterally — this twists the reinforcement fabric and weakens the burst pressure over time.

Connections: Use standard camlock fittings (Type C female or Type E male) for quick connection to pumps. Ensure the gasket is seated before locking the cam arms. For aluminium irrigation pipe, Type A and Type B adaptors are available.

Pressure testing: Before each season, pressurize the hose to working pressure and check for weeping at couplings and along the hose body. Replace any section that shows signs of delamination or external scuffing deeper than 0.5 mm.

After use: Drain the hose completely before rolling. PVC will develop permanent creases if rolled tightly while wet and stored in direct sunlight for extended periods. Store coiled rolls in a shaded, cool location between uses.

Winter storage: In freezing climates, drain and dry before storage. PVC becomes temporarily stiff below −5 °C but does not crack unless under pressure. Never store a water-filled hose where it may freeze.

Construction & Materials

· The performance of a layflat hose comes entirely from how it is built. Each Sunhose layflat hose is manufactured with three distinct layers.

· Inner PVC lining. A smooth, flexible PVC compound that minimises friction loss and resists corrosion. The inner bore stays chemically inert when carrying clean water, irrigation water, or mild agricultural chemicals.

· Polyester textile reinforcement. High-tenacity polyester yarns are woven in a continuous circular pattern around the tube. This braided structure is what allows the hose to handle pressure without ballooning or twisting. The number of yarn layers determines the pressure rating — standard duty uses a single reinforcement layer, while heavy duty grades use two or more layers for working pressures up to 150 PSI.

· Outer PVC jacket. The jacket is compounded with UV stabilisers to resist sun degradation during prolonged outdoor use. It also provides abrasion resistance against concrete, gravel, and rough ground surfaces.

· This three-layer construction means the hose is significantly lighter than rubber alternatives of the same diameter while still delivering reliable pressure performance across seasons.
