With the cost of heads being relatively cheap it's not even a question in my mind - replace them.

I am concerned that the operating elements on the remaining sprinkler heads have been weakened by the pipe movement during the collapse and would fail once we do the hydrostatic test on the system, causing water damage to the stock. Are there any guidelines for determining whether the remaining heads need to be replaced? (A visual inspection revealed no apparent damage to these heads.) Thanks, David Bitton, Eng.
