In the warmer months of the year, police reports often mention accidents or environmental damage caused by burst hose lines. It is not uncommon, for example, for agricultural or construction machinery to be affected by a burst hydraulic hose line, causing the emergency services to be called out. No less annoying are burst water hose lines. The colloquially known "solar hoses" are used for solar thermal energy and are often installed on roofs. If they burst there, the leaking water can cause considerable damage to the building. Similarly, an unknowingly failed hose line for irrigation can lead to considerable crop damage. There is often a common cause: an outdated or unsuitable hose line.
Damaging factors such as ozone, UV radiation (sunlight) and high temperatures can cause the hose to age prematurely and crack. If several factors come together, for example at the height of summer in strong sunlight, the hose can fail.
Particular caution is required where cheap or unsuitable products are used for temperature control. For example, black PVC hoses become so soft due to high temperatures that they can detach from the mounted fittings. Rubber hoses or plastic pipes are also affected. It should be borne in mind that in our latitudes, the water in a garden hose can quickly reach 60 °C in summer. If a hose line is not lying in the grass, but on a roof with tar paper or in a depot on dark asphalt, much higher temperatures are possible.
To be on the safe side, purchasers should not buy minimum qualities, but rather hose qualities that are stronger and more durable in the long term.
