The most effective method for resupplying foam from a tender is through transfer using a pump. This method allows for a controlled and efficient transfer of foam concentrate from the tender to the desired location or equipment where it is needed. Utilizing a pump ensures that the foam can be moved at an appropriate rate and pressure, which is essential for maintaining operational effectiveness during firefighting activities.

When foam is pumped from the tender, it can be proportioned with water effectively, allowing for the generation of the appropriate foam solution that is critical for suppressing flammable liquid fires. This method also allows for flexibility in resupply efforts, as hoses can be extended over a distance, enabling support in various scenarios, especially in larger incidents.

Other methods, such as gravity feed, provide a more limited capability, relying on the elevation of the tender to allow foam to flow. This can lead to slower resupply rates and may not effectively suit situations where speed and control are vital. The use of a hose reel, while convenient for deployment, may not be ideal for resupplying foam, as it is typically designed for the delivery of water instead of foam concentrate. Fire truck integration could be beneficial in some contexts but is generally less effective than using a dedicated pump for transferring foam
