GUC holds semi-annual tester's certification courses, in the spring and fall, to enable plumbers and technicians to better service the needs of our customers. The tester’s certification courses are part of our comprehensive program designed to protect our water system from harmful cross-connections. All backflow testers must complete a re-certification course every two years.
Courses are subject to change or cancellation in accordance with CDC, State, and GUC policy.
