What typically happens to a flexible hose if it hasn't been maintained correctly?

A flexible hose that has not been maintained correctly can indeed develop leaks. This can occur due to several reasons, including wear and tear on the material or the connections at either end. Over time, exposure to environmental factors such as UV radiation, extreme temperatures, or chemicals can degrade the hose material, leading to cracks or weak areas that allow fluid to escape. Regular maintenance helps to identify and mitigate these issues before they lead to leaks, ensuring the integrity of the system remains intact.

In considering the other possibilities, kinking often occurs when a hose is improperly stored or subjected to bends that exceed its capacity. A hose might burst if it is exposed to pressures beyond its rated specifications, which is typically a result of neglecting to monitor the pressure, especially in high-pressure environments. While hardening can occur due to aging or exposure to heat and other factors, this does not directly lead to an immediate failure like leaking does. Thus, developing leaks is a crucial and more immediate concern when reflecting on improper maintenance of flexible hoses.
