Now that you “checked out” hopefully YOU will have more time to learn this trade properly.
I would strongly suggest you stop trying to learn by watching other BUT possibly getting an up dated NFPA 13 book to start off Then possibly learning a few plumbing codes. Contact a trade association to enlighten you in ALL the really techinical aspects your lacking in. Lead wiping is still alive and well in most civilized countries, so is knowing various codes. The problem with some licensing laws are all different and lots of folks get by calling “plumbers” without any formal training NOW that your gone TRY to learn something good luck and have a great life. We will miss you
