I assume it has something to do with my sprinkler system, but I'm not totally sure.

Just a guess, but it looks like some sort of flow regulator for the sprinkler system.
edit: maybe an air bleeder valve for the sprinkler system?

Looks like some type of pressure relief valve.

Looks like a vacuum breaker to prevent your sprinkler water from being suck back into the potable water sytem of your house.

The cap looks adjustable, what happens if you move it to the different levels?

(I cannot read the little letters beside the different levels, what do they say or indicate)
