Master Plumber
Skilled TradesYou've passed the master's exam and can now design plumbing systems, pull permits, and sign off on work that other plumbers did. You're the person the inspector calls when something doesn't make sense. You can look at a building's plumbing and tell the decade it was built. The license took years to earn, it's the most respected credential in the trade, and it means you never have to wonder if you'll find work.
