In which part of the system would you install an inline foot valve for drafting?

Installing an inline foot valve for drafting is most effectively done at the pump inlet. The pump inlet is where water enters the pump from the source, and incorporating a foot valve in this location is crucial for maintaining a prime in the pump system. The foot valve prevents backflow of water once the pump is shut off, ensuring that the pump remains primed and ready for operation when needed. This setup is particularly important during drafting operations, where the water is being drawn from a static source like a body of water, as it ensures a consistent supply to the pump without losing suction.

Placing the valve elsewhere, such as in the hose line, suction supply, or tank outlet, would not serve the same purpose effectively. For instance, if installed in the hose line, it may restrict water flow and create unnecessary friction loss. If positioned incorrectly, it could also lead to inefficiencies or complications in the drafting process. Installing it at the pump inlet, however, maximizes the pump's efficiency and operational reliability, making it the ideal choice for this setup.
