What Plumbing Work Can Be Done Without a License?

You cannot do plumbing work in Indiana without a license. Apprentices are the only exception, but they must work with a licensed plumber.

What are the Different Types of Plumbing Licenses Available in Indiana?

To become a licensed plumber in Indiana, you must first work as an apprentice and then a journeyman. You are required to be at least 17 years of age to become an apprentice.

The average wage for plumbers in Indiana ranges from $10 to $50 per hour. While apprentices make around $10 per hour, journeymen can make $25 per hour or more. Experienced plumbers get paid up to $50 per hour. 

Typically, apprentice plumbers will clean lines and assemble parts. They also can respond to questions from customers and prepare job sites. A journeyman plumber is responsible for following state codes, testing components, assembling parts, and installing new plumbing supplies.

There’s a high need for plumbers. The average career length ranges from 10 to 20 years. Some plumbers retire early due to the long hours and physical constraints.

How to Get a Plumbing License
