How do wet pipe sprinklers work?

How do you drain a wet fire sprinkler system?
Close both valves at the system’s auxiliary drains if they’re not already closed. Remove the plug in the bottom valve, and place a container there to capture drained water. Open the top valve slowly until it’s completely open, then let any water drain out. Close the bottom valve.
