NFPA 13 (10) section 11.3.1.1 also includes “adjacent”. What does this mean actually? 4 heads on the same line regardless of the walls or 4 heads in the same area but may be supplied from different lines? The pictures in the appendix are not very clear. Thanks, Dewayne *From:*

Pitot flow test kits

Anyone else have a problem with these new pitot flow test kits with the air “quick” couplings for the gauge rusting up and giving inaccurate readings? If so what have you done about it? I am thinking we should remove the gauge from the coupling after every use and blast it with WD-40 or the
