Which factor must be considered when using suction hoses?

When using suction hoses, the type of strainer is a critical factor to consider. Strainers are essential components that prevent debris from entering the hose and subsequently the pump, which could impair performance or cause damage. Different types of strainers have varying capabilities in terms of water retention and the size of debris they can filter.

For instance, a strainer with larger openings might allow more water flow but also runs the risk of letting in larger particles that could obstruct the pump or cause operational issues. Conversely, a strainer designed for finer filtration might restrict water flow or become clogged more quickly. Therefore, the choice of strainer directly impacts the efficiency and effectiveness of suction operations, making it the most pertinent factor among the options.
