You hit it on the nose when indicating that the 1" restriction is on PIPE. Does this limit apply to fittings? Well the real question since we know 1/2" outlets are ok is not the standard fitting but nipple extensions. That's an issue that the standard has not yet addressed. There have been cases where 2 or 3 extensions have been combined (and probably not included in the calculations). I believe something on it will be in the next addition.
