What is an unacceptable way to increase your available water?

The approach of opening your tank-to-pump is considered unacceptable for increasing the available water supply because it does not directly enhance the water available for firefighting operations. The tank-to-pump valve is designed to allow water to flow from the apparatus's storage tank to the pump, but this does not increase the overall quantity of water; it merely makes the water in the tank available for use. The other options focus on methods that effectively enhance the water supply for firefighting:

• Eliminating kinks in supply lines improves water flow and maximizes the volume reaching the pump.
• Connecting to all hydrant discharges can supplement an existing supply, ensuring a greater volume of water is accessible during firefighting efforts.
• Getting supply from another engine directly adds to the amount of water available for use, thus enhancing firefighting capabilities.

In summary, opening your tank-to-pump does not facilitate an increase in water availability, making it an unacceptable choice in the context of enhancing firefighting resources.
