Why when I read through all of these posts everyone does things diffrent according to whatever code they are useing? Why the heck are their so many diffrent types of codes? Wouldn't it be easier to have 1 national code so every plumber and inspector is on the same page? Being a new guy to the industry it is so frusterating trying to figure out which code to learn. How do we protect the nation when most inspectors dont know their own ass from a hole in the ground and ARENT EVEN PLUMBERS?! We as an industry can't decide what code and regulations to follow, yet were supposed to protect the nation? WTF
