My question is since he just started this buisness 3 years ago, how did he all of the sudden learn how to do plumbing. Yes some plumbing is simple, but are you going to hire me to work on your commercial pool if all the training I have is a book from home depot? Thats why I was asking. I don’t remember any posts from DS the past 3 years stating he went to plumbing school or had an apprenticeship other than playing with his pipe snake at night, So I was curious how that came about.
