In the recommended pump-in-service sequence, what action follows priming?

Explanation:
Priming fills the pump and suction with water, eliminating air so the pump can develop flow. Once that is done, opening a discharge line to build pressure is the next step because it starts moving water out of the pump into the system, establishing the necessary discharge pressure for workable flow to the attack lines. Connecting to the water source and bringing the engine to rated speed are steps that occur earlier in the sequence, and opening additional lines generally comes after initial pressure is established.
