Anytime a sprinkler is moved, it is potentially susceptible to damage, even if the line with an upright is backed out and left in the hanger. Or when a head in a flexible drop is moved from one location to the other. Do you require a new sprinkler every time a sprinkler is moved? Moved by how much? I think this comes down to practicality and risk tolerance.
