To avoid someone form dancing on that thin ice, the cut sheet
identifies the equivalent length of the device but then introduces
some ambiguity by saying: The hydraulic loss of the Flexhead
connector needs to be included in the hydraulic design calculations
the same as a valve OR FITTING. Was doing fine until the last two
words since as you pointed out, 13 says ignore the FITTING that is
directly connected to a sprinkler. Calling it a connector helps
indicate the intent.

Hey Roland, Since section 22.4.4.7(9) states that we can ignore the
fitting attached to the sprinkler and a Flexhead is considered a
fitting and is attached to the head, can the friction loss in it be
ignored?
