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

Suction hose diameters being at least as large as the pump inlet port is essential for maintaining effective water flow and pressure during operation. A diameter that matches or exceeds the pump inlet ensures that the pump can draw water without restriction or excessive turbulence, which could reduce its efficiency and potentially lead to cavitation. Proper sizing of the suction hose helps to facilitate a smooth and continuous flow, preventing blockages that could lead to operational issues.

The correct size also helps in preventing air from getting into the system, which could disrupt the pump's performance and potentially damage it. Ensuring that the suction hose diameter aligns with the pump inlet port is therefore key for optimal performance in any aquatic pest control activities.
