Relating to the licensing and regulation of persons who may repair or test backflow prevention assemblies.

HB 4293 requires anyone who repairs or tests backflow prevention assemblies (devices that prevent contaminated water from flowing back into clean water systems) to hold either a state-issued license under Texas Water Code Chapter 37 or certification from a nationally recognized accrediting organization. This directly affects plumbers, technicians, and other professionals working on these critical water safety systems. The bill amends the Health and Safety Code to establish these licensing standards, which take effect September 1, 2025. It focuses on ensuring qualified personnel handle backflow prevention work to protect public water safety.
