As a rule of thumb, suction hose diameters should be at least as large as what?

Suction hose diameters should be at least as large as the pump inlet port because this ensures that there is adequate flow and minimizes the risk of creating a vacuum that could collapse the hose or starve the pump of water. When the diameter of the suction hose matches or exceeds the size of the pump inlet, it allows for optimal water volume to be drawn in, which is crucial for the effective operation of aquatic pest management systems. A larger suction hose can also help reduce friction loss and maintain a steady flow of water, leading to improved efficiency in the pumping process. This principle is essential in managing water-based systems, as proper sizing directly influences the effectiveness of pest control efforts.
