Re: TPR air gap
Dom,
Those aren't any good.
Did you open the T&P and test it?
Water spurts out of that air gap all over. At least is did from all the ones like it I've tested.
Like Phillip said ... trying to meet the 'intent' of the code without really understanding the 'reasoning' behind the 'wording' of the code.
An air gap is not just to serve as an atmospheric breaker (except for hose bibbs), but to serve as an 'air space' across which cross or back contamination will be prevented. Those may serve as an atmospheric air break, however, being as this is not a hose bibb, it needs back flow protection which will also provide an 'air gap' (i.e., and 'air space') which will prevent cross or back contamination.
