NITC Journey Level Plumber 2015 (CK) The CK exam maps water supply systems, drainage principles, venting configurations, and gas piping layouts across residential and light commercial installations. Fixture installation, trap mechanics, and code-compliant rough-in work form the assessment core. Practical knowledge of material selection—copper, PVC, cast iron—and pressure testing round out the technical scope you’ll need.
