What is necessary for proper operation when suction hose is required?

The necessity for strainers when using suction hose is crucial for proper operation in fire service applications. Strainers are designed to prevent debris from entering the pump and causing damage or operational issues. When water is drawn from a low source, such as a pond or lake, it is essential to filter out any large particles or contaminants that could impede the pump's function. By using a strainer, firefighters can ensure a reliable flow of water while protecting the equipment from potential blockages. This is vital in maintaining an uninterrupted water supply during firefighting operations, especially in suburban settings where access to clean water sources may be varied.

While valves control the flow of water and adapters facilitate connections between different hose sizes or fittings, and pipes convey water, strainers are specifically focused on safeguarding the pump and ensuring its efficiency in suction operations.
