This guy wrote a whole article outlining how bad and unusable the British pipe standards are and you’re surprised the two (ish) continents that don’t use them are actually pretty happy with their standard and don’t want the other?
NPT has some flaws and complexities but generally while it’s comprehensive conventions and practices mean that for specific types of plumbing you’ll need some specific standard fittings and once you get used to them that’s pretty much that. From gases to liquids. None of this “whoa someone decided to use a tapered one here” you don’t get to chose what fitting you’re feeling like that day, we have building codes and if it’s a pipe in a wall carrying water than there’s a convention (and likely building code) that tells you your pipe, fitting, and which way the threads should turn! (Generally in the broadest strokes: Explosive gases are reverse threaded. Everything else isn’t.)
Anyway we’ve been saying no to bad British ideas since 1776. Don’t blame us outside the Americas the rest of you (and ISO) fell for it.
