My concern is my family's safety and following the ABYC "codes" insures that the system is installed as safely as possible. While I have and recommend insurance, my insurance company does not have the expertise in this area that the ABYC has.
I am a hands on technician. Safety comes first. As a general rule my systems will exceed ABYC. First stop is Caulder, even if I plan to have another qualified tech do the work with my OK on design, I read Neville Caulder.. I trust no one until I can at least understand the subject, the whys and what fors.
That being said, ABYC may not be all it is cracked up to be. We're it so, they would not be constantly changing their specs. Common sense, advise from more than 2sources and reading up on the subject. This forum has a wealth of information from some very knowledgable people, like FF for instance. Even then, the bottom line is...you are the Captian.
