No....I am neither a plumber or a heating contractor. By the time I was old enough, my grandfather had sold the business, and my father had gone to work in a factory. I am a machinist by trade, and somehow, over the years have done a lot of plumbing and pipe-fitting. I'm the kind of person, that would read a technical manual 100x's until I understand it, if necessary. I guess, I'm like you, I have never run into something I can't do, if I set my mind to it. Heating interested me, because of my own system.The internet supplies endless information.
