What type of hose is used to deliver water from a hydrant to an engine?

The use of supply hose is specifically designed for delivering water from a source, such as a fire hydrant, to the fire engine. This type of hose typically has a larger diameter to accommodate the higher volumes of water flow necessary for fighting fires and other emergencies. The supply hose is built to withstand the pressure of water being pumped from the hydrant without bursting or leaking, ensuring a reliable source of water for firefighting operations.

Attack hoses, on the other hand, are smaller in diameter and are used for delivering water from the fire engine to the fire or situation requiring suppression. Discharge hoses refer to hoses that direct water out of the pump and do not serve the purpose of bringing water into the engine. Hard suction hoses are used to draw water from static sources such as ponds or tanks and are not typically utilized when water is being supplied from a hydrant. Thus, supply hose is the appropriate choice for this scenario as it fulfills the function of connecting the hydrant system to the engine for efficient water delivery.
