What should be done with the rope connected to the barrel strainer?

The choice to tie off the rope connected to the barrel strainer is correct because it ensures that the strainer remains in the proper position during operation. Proper positioning of the strainer is crucial for efficient water drafting, as it needs to remain submerged and stabilized in the water source to function effectively.

If the rope is left loose, it could lead to the strainer being pulled out of the optimal position, causing it to suck air instead of water, which would hinder the drafting process. Cutting the rope would eliminate its utility altogether, risking the strainer's stability. Similarly, attaching the rope to the truck may complicate the operation and doesn't provide the necessary stability to keep the strainer in place. Therefore, securing the rope by tying it off is essential for maintaining proper functionality and safety during operations.
