Here are a couple of ways in which I hope that will happen. Apprentices just starting out could earn 30 to 50 percent less than a fully trained plumber as they learn the trade. Teacher plumbers often have six-figure salaries because their skills and knowledge are scarce. The variables that determine salary include education in the plumbing school, where you work, your level (apprentice, officer or master plumber), years of experience, the type of work you do, and the type of employer for the that works.
