In priming sequence, which valve should be opened first?

Explanation:
Opening the priming valve first is essential because priming fills the pump and suction line with water to remove air and establish a continuous water column. This prepares the pump to develop suction and operate without dry-running. If you open discharge valves or start the pump before priming, air can enter the system or the pump can run dry, making priming ineffective. Closing the priming valve would prevent water from entering the pump for priming.
