I'm a Journeyman plumber in Texas, and will be getting my masters next summer. I have a question-what does it take to run a plumbing business in Arizona? Do they have similar system that we have in Texas? In Texas you have to register as a apprentice then after 8,000 hours you can go take your state exam to be a Journeyman plumber. After holding your Journeyman's for a year you can go take your Master's and run a business. How does it work in Arizona? If I was to move to Arizona what would my Texas Journeyman's license get me? How long before I could open a business in Arizona?
