Thank you Steve. While I sometime disagree with your perspective, on this we both agree, and wholeheartedly! I am regularly irritated by our industry generated "slang" vernacular. "Heads", "sprigs", "drops", "shotgun risers", and "FDC Connections" to name a few, should be systematically expunged from our vocabulary, and I will lay down this challenge to the Professionals, Tradesmen, Scholars, Authorities, and all other participants of this Forum to do this.

The term "sprinkler head" - which is and has been used for the entirety of recorded history as we know it - is not a defined term. As such, there is no such thing as a "sprinkler head" and therefore, no such entity or group of stake-holders as "head makers", lest you be referring to fire pumps, plural/inclusive. We've all done it, said it, used it, myself included but there is no such thing as a sprinkler head. Let's all start referring to them as "sprinklers" or "fire sprinklers" ...
