What is hard suction hose primarily used for?

Hard suction hose is specifically designed for drafting water from static sources, such as ponds, lakes, or reservoirs, where the water needs to be pulled up and into the fire apparatus. This type of hose has a rigid construction that allows it to withstand the negative pressure created when water is drawn from such sources. Unlike flexible hoses, hard suction hose can effectively maintain the integrity required to prevent collapse during the drafting process.

When setting up for a draft operation, fire fighters will typically connect the hard suction hose to the pump on their apparatus and lower the hose's strainer into the water source to ensure that the pump can effectively draw water. The capability to draft from these sources is essential, particularly in situations where fire hydrants are unavailable or insufficient for firefighting efforts.

Therefore, the primary use of hard suction hose is critical in ensuring that firefighters have access to water from various static sources, facilitating their readiness and effectiveness in fighting fires when needed.
