What must go on the end of the suction hose before it is placed in a portable tank for drafting?

The inclusion of a strainer on the end of the suction hose before it is placed in a portable tank for drafting is crucial for several reasons. When drafting water from a body of water or a portable tank, the strainer serves to filter out debris and prevent unwanted materials—such as leaves, twigs, or sediment—from entering the pump system. This is vital for maintaining the integrity of the pump and ensuring that it operates efficiently without becoming clogged or damaged.

Using a strainer also helps create a vacuum within the suction line, which is necessary for drawing water into the pump. It ensures that water can flow freely while maintaining the desired pressure without interruptions caused by potential blockages. Overall, the strainer is an essential component when drafting to ensure that only clean, unobstructed water reaches the pumping system and to prevent mechanical failure due to foreign materials.
