What is the recommended practice for refilling a mobile water supply tank from a static water source?

The recommended practice for refilling a mobile water supply tank from a static water source is to use a drafting technique. This method involves creating a vacuum that allows water to be drawn from the source into the tank.

Drafting is effective because it utilizes the inherent pressure difference created by the pump in the mobile water supply apparatus. By lowering the intake hose into the static water source, the pump can then draw water up through the hose and into the tank. This method ensures a steady and reliable supply of water without relying on external forces like gravity or pressure, which might be insufficient in certain situations.

Understanding why drafting is the optimal choice in this context highlights its ability to function effectively in varied scenarios, ensuring that the mobile water supply can efficiently refill not only promptly but also safely.
