Requirements

Texas HVAC plumbing licensing is administered by TDLR (the Texas State Board of Plumbing Examiners merged with TDLR in 2019). To obtain a Journeyman Plumber license, you must accumulate the required hours of on-the-job plumbing experience under a licensed Journeyman or Master Plumber. Many applicants follow a two-step path: first obtaining a Tradesman Plumber-Limited license after approximately 4,000 hours, then continuing to accumulate hours toward the full Journeyman license. After completing the required hours, you apply to TDLR, pass the PSI written exam, and pay the license fee. [VERIFY current hour requirements and Tradesman path at tdlr.texas.gov]
