What is the term for transferring the supply of water from the internal apparatus water tank to an external source?

The term describing the transfer of water from the internal apparatus water tank to an external source is known as a changeover operation. This process typically involves the apparatus, such as a fire engine, transitioning its water supply to receive water from an external source rather than relying solely on its onboard tank. This is often crucial in firefighting situations where maintaining adequate water supply is vital, and it allows firefighters to continue their operations without interruption.

In contrast to this concept, reverse lay refers to a technique in hose deployment where firefighters pull the hose back from an incident to the pumper, facilitating efficient connection to hydrants while maintaining a steady flow of water during firefighting. Load shedding concerns the management of electrical loads to prevent overloads, and inverters deal with converting direct current (DC) to alternating current (AC) in electrical systems.
