Frequently Asked Questions

Products

A layflat hose is a collapsible, flexible hose designed for transporting liquids under pressure.

It lies flat when not in use for easy storage and transport, and expands when filled.

Our hoses are reinforced for high performance in heavy-duty environments.

Our hoses are made using high-tensile polyester reinforcement and are coated with thermoplastic polyurethane (TPU) or other polymer blends depending on the application.

These materials offer excellent abrasion, UV, and chemical resistance.

Yes. Our hoses are engineered for high-pressure applications and tested beyond rated limits.

Each product specification sheet includes burst pressure and working pressure ratings to help guide selection.

Absolutely. We supply a variety of diameters (1.5″ to 8″) and lengths to suit different flow rate and distance requirements.

Custom lengths and assemblies can also be provided on request.

Industry Use

Our hoses are designed for use in agriculture (irrigation, fertigation), mining (dewatering, slurry transfer), construction (site water, bypass pumping), and emergency services (municipal potable water supply).

Yes. We offer hoses with high chemical resistance specifically for slurry, liquid fertiliser, and corrosive liquid handling.

Please contact us for advice on the best hose for your application.

Yes. Our high-flow and abrasion-resistant hoses are ideal for temporary wastewater bypass and dewatering operations in municipal and construction settings.

Ordering, Shipping & Warranties

Delivery time depends on stock availability and your location. We typically dispatch within 1–3 business days for in-stock items.

Please note that delivery times are subject to third-party carriers and may vary.

Custom orders are subject to lead times, which are confirmed at the quotation stage.

Yes, we deliver to all regions across Australia using reputable carriers.

For remote or regional areas, additional delivery time may apply.

Yes, our hoses come with a 12-month warranty against defects in materials and workmanship under normal use.

This excludes fair wear and tear, misuse, accidental damage, or damage caused by external impact.

Please refer to our terms and conditions for full details.

In the rare case of failure due to a manufacturing defect, we will assess the hose and may offer a repair, replacement, or refund in line with the Australian Consumer Law.

However, improper use or environmental damage is not covered.

Returns for non-faulty items are considered on a case-by-case basis and may incur a restocking fee.

Please contact our team within 7 days of receiving your order to discuss.

Technical & Installation

Store the hose in a cool, dry place out of direct sunlight.

Avoid prolonged exposure to sharp edges or heavy loads.

When possible, keep hoses loosely coiled and clean for longevity.

Some of our hoses can handle moderate vehicle traffic when used with hose ramps or protectors.

However, repeated impact may reduce lifespan.

For frequent traffic areas, we recommend protective measures to reduce the risk of damange.

Factors such as pressure, temperature, fluid type, and distance all impact hose selection.

You can consult our technical datasheets or speak with our team for a recommendation based on your specific needs.

Yes, we offer hose assemblies with a wide range of fittings, including camlocks, Storz, Bauer, V-clamp and more.

Custom assembly configurations are also available upon request.

To ensure safe operation, always use layflat hoses within their rated working pressure, not their burst pressure. Burst pressure is a safety factor only and must never be used for hose selection.

The burst pressure is the maximum pressure the hose can withstand before failure, but it should never be used as a guide for regular operation. Always select hose based on Working Pressure (WP), not burst pressure.

To determine the pressure your hose must handle, consider:
• Vertical lift (static head) Water pressure increases by approx. 1 bar per 10 m of lift.
• Pump discharge pressure The pressure your pump produces at the operating flow rate.
• Friction loss Caused by hose length, internal diameter, fittings and flow velocity.
• Pressure surges Created when pumps start or stop suddenly or when valves are closed quickly.

For high head heights, long hose runs or aggressive pump cycles, always select a higher pressure rated hose.

Regularly inspect hoses for wear, kinks, and signs of damage, and avoid sharp bends or dragging over rough surfaces while under pressure.

Hose deformation (collapse or flattening) is usually caused by incorrect application or installation.

The common causes of this are due to:
• Using discharge hose on the suction side of a pump
• Blocked strainers or restricted inlets
• Excessive suction lift or starving the pump

To avoid this, always use a proper suction hose on pump inlets. Discharge hoses such as layflat, PVC and bore hose are designed to operate under positive pressure, not vacuum.

The common causes of kinking or sharp folding are due to:
• Tight bends or routing around corners
• Twisting during deployment
• Excessive flexing immediately behind couplings

To avoid these issues, always install hoses with smooth sweeping bends, avoid tight radii and deploy hoses straight without twist.

There is no single “best” diameter. The correct size is the one that keeps your pump operating efficiently while minimising friction loss.

 

The trade-off

Smaller diameter hoses create higher water velocity and greater friction loss, which increases pump load. However, they are lighter, easier to handle and generally lower cost.

Larger diameter hoses reduce water velocity and friction loss, which lowers pump load and improves efficiency over long distances. The trade off is increased weight and higher upfront cost.

 
How to choose

1. Identify your required flow rate.
2. Choose a diameter that keeps velocity moderate.
3. Check your pump curve and select the size that keeps the pump near its optimal operating range.
4. For long distances or high flow, always consider stepping up one diameter.
Using hose outside its recommended flow band increases energy consumption, wear and downtime.

Still unsure?
Provide AGMIN with your:
• Pump model
• Flow rate
• Hose length
• Vertical lift
• Application type
and we will recommend the correct hose type, pressure rating and diameter for your system.
