Also joining them in the list of successful examinees were 149 other Louisians from the SLU School of Engineering and Architecture (SEA), bringing the university's total number of newly licensed master plumbers to 151.

A master plumber is a licensed professional responsible for designing, installing, inspecting, repairing, and maintaining plumbing systems in residential, commercial, and industrial buildings. Beyond ensuring the reliable supply of clean water and the safe disposal of wastewater, master plumbers play a critical role in protecting public health by preventing water contamination, sanitation-related diseases, and unsafe plumbing installations.

Obtaining the license requires passing a rigorous national examination that measures competence in plumbing design, building and sanitary codes, hydraulics, water supply systems, drainage, mathematics, engineering principles, and professional practice.

The July 2026 Master Plumber Licensure Examination was administered on July 11 and 12 in testing centers across NCR, Baguio City, Butuan, Cagayan de Oro, Cebu, Davao, Iloilo, Koronadal, Legazpi, Lucena, Pagadian, Rosales, Tacloban, and Tuguegarao City.

Topping this year's examination was Jim Rey Del Castillo Bacarisas of the Cebu Institute of Technology-University, who posted the highest rating of 91.30%.
