STEP 3: Apprenticeship

You can choose to do an apprenticeship instead of school, or after you finish school (recommended). How long you need to be an apprentice will vary by state but typically an apprenticeship will last 2-4 years.

Pay during an apprenticeship is typically much lower since during this time you will be essentially learning from a more experienced plumber.
