Main risks

• Rupture due to overpressure or excessive vacuum, with possible hose “whip” and water discharge.
• Leaks or disconnections at couplings and clamps that may cause flooding and property damage.
• Collapse from excessive bending or crushing, reducing the flow rate and potentially damaging the pump.
• Suction of sand, sludge or foreign objects causing blockages or premature wear.
• Deterioration due to chemical incompatibility or unsuitable temperature of the pumped liquid.
• Ageing from sun, ozone or abrasion, leading to cracks, hardening or bulging.
• Trip and fall hazard from hoses laid across walkways.
• Water spraying towards nearby equipment or electrical sockets.

Safe use

• Check the hose’s compatibility with the intended liquid, working pressure and temperature.
• Inspect before each use: do not use if there are cuts, cracks, bulges, hardening or corrosion on couplings.
• Fit couplings of the correct diameter and secure with suitable clamps; verify tightness without constricting the hose.
• Maintain generous bend radii; avoid stepping on it or crushing it with vehicles or objects.
• On suction lines, keep the line airtight; prime the pump as required and use a strainer at the intake to retain solids.
• On discharge, pressurise gradually and open/close valves slowly to avoid water hammer.
• Secure and guide the hose to prevent sudden movement; keep people away from pressurised connections.
• Disconnect the pump power and relieve pressure or vacuum before uncoupling; drain the contents in a controlled manner.
• Avoid directing the flow towards people, sockets or electrical equipment; protect sharp edges and corners.
• For submerged intakes, position the end some distance above the bottom to minimise the suction of sediments.

Storage and maintenance

• Rinse with clean water after use with dirty water; if other liquids were pumped, follow the manufacturer’s instructions for rinsing.
• Drain completely and allow to dry to prevent mould, unpleasant odours and damage from internal freezing.
• Store coiled with wide curves, without forced kinks or twists; do not hang from a single point.
• Protect from direct sunlight, ozone, heat sources, oils, solvents and sharp objects.
• Keep the ends capped to prevent the ingress of dust, insects or dirt.
• Periodically check couplings, seals and clamps; replace them if they show wear or rust.
• Replace the hose if cracks, bulges, softened areas, abnormal stiffness or leaks appear.
• Store in a dry, ventilated place, out of reach of children and rodents.

Restrictions of use

• Do not exceed the service pressure, permissible vacuum or temperature range specified by the manufacturer.
• Do not use with compressed air, gas or steam.
• Do not pump fuels, oils, solvents or other chemicals unless the hose expressly indicates suitability.
• Do not use for drinking water or food applications unless specifically indicated.
• Do not use the hose as a securing, lifting or towing element.
• Do not pierce, burn, weld or attempt repairs with tapes or adhesives that may fail under pressure.
• Do not leave the pressurised system unattended for prolonged periods.
• Do not allow use by minors; installation and handling must be performed by adults familiar with water pumps and basic plumbing.
