What could indicate improper installation of a flexible hose?

Improper installation of a flexible hose can manifest through specific indicators that threaten the functionality and safety of the system. In this context, the correct choice encompasses two key symptoms: lack of flexibility and excess slack.

Lack of flexibility in a flexible hose suggests that it may have been installed incorrectly, potentially causing stress on the hose itself or the surrounding connections. A correctly installed flexible hose should easily bend and accommodate movement without becoming rigid, which could lead to cracks or leaks over time.

Excess slack is another critical indicator of poor installation. A hose with too much slack can create unwanted movement, leading to vibration, misalignment, or increased wear at connection points. This excess slack could ultimately result in failures due to the strain on the fittings or hoses when under operational pressure.

By recognizing both a lack of flexibility and excess slack, one can diagnose improper hose installation effectively, ensuring that the entire system operates safely and reliably. Thus, identifying both these conditions in tandem serves as a comprehensive approach to verifying proper hose installation.
