Good for you....you are in his fan club.....nice...personally I am not here to impress anyone...my goal is to learn from others and help people in areas I have expertise...such as onboard evaporated water potentially containing high levels of sodium....or onboard water potentially causing discoloration of dyed hair. You see, being a sea going sailor...I have learned a long time ago nothing is absolute.....in this case, for someone to speak in absolutes with countless posts supporting their theory and dismissing what can potentially happen will only come back to haunt you. Murphy's law so to speak. A good engineer is always aware of the intangibles and does not speak in absolutes. However if they do, I am sure it has or will be brought to their attention in reviews from superiors.
