During the vacuum test, what is the next step after checking for foreign matter in the hard suction hose?

After checking for foreign matter in the hard suction hose, the logical and necessary next step is to connect the hard suction hose to the pump intake connection. This action is crucial because it establishes the linkage between the water source and the pump, allowing for the subsequent processes involved in drafting and pumping water. Ensuring there are no obstructions in the hose is vital as it could impede water flow; therefore, following this check with a connection ensures that the system is ready for operation.

Establishing this connection allows for the pump to create a vacuum, which is essential for drawing water from the source, whether it be a static supply like a lake or pool, ensuring that when the pump is activated, it can efficiently move the water. Each subsequent step such as filling the tank, inspecting for leaks, or calibrating the pressure gauge depends on the successful connection of the hose to the pump intake, illustrating why this step is foundational in the operation procedure.
