Winterization, turned water back on

]I recently had my sprinkler system blown out by a professional for the winter. However, my outdoor water faucets are connected to the same water as the sprinkler system. I turned the outdoor water back on to be able to use the outside faucets for a few projects this weekend. By turning that water back on does that automatically fill my sprinkler lines? Will I have to get them blown out again? I wasn't sure if I could just drain the pipe out in my basement where my backflow preventer is located. My backflow preventer is located in my basement and is a FEBCO 825Y if that means anything.

You need to invest in some plumbing alterations. Your situation should never have to occur.

You will have water all the way to the zone valves. Not past them into the lines where the sprinklers are, but up to the valves for sure.

An isolation valve should be added to the line that leads to your sprinklers supply line point of connection.
