I have occasionally been hit with that. The reason is that threaded unions are
notoriously prone to leak. I will not use them on anything that can be grooved
instead for this reason. I will use them down stream of a drain valve but
otherwise try to avoid them.

had an inspector say that all threaded union fittings must be accessible
(access panel provided for union behind sheet rock). I have hear that this is a
requirement for domestic water piping, but I have never heard about this for
fire sprinklers. Does this ring a bell with anyone? Thanks! Matt
