how long does it take to become a certified plumber?
Well in Minnesota I belive Dunwoody Institutes have it.... Otherwise you can apply at a shop... Have them train you and go for your journeyman's license when you get enough hours in....\n\nI'm not sure how many hours you have to work... But I want to say a couple years...\n\nIt's almost better to get on the job training... then you can work with different people and learn many different ways of doing stuff....And your company might pay for you to take the test...\n\nGood Luck
