There were "passive purge" systems installed for a while. Go to the last head, add a tee & tie it into the water closet supply line. It helped to purge the stagnate water from the sprinkler system, if I remember correctly, these were installed this way, pre-back flow requirement. This was done in the north east on 13D systems for a while, not sure if they're still installed this way.
