Called to a residential customer's home for an emergency plumbing repair. The customer had a water leak and could not find the source. I used my skills and experience to diagnose the issue and perform the necessary repairs. Found that the water consumption had increased over the past 90 days, indicating a pipe leak. We used pressure and acoustic tests to locate the leak and then shut off the water valve, applied a pipe repair clamp, and replaced the damaged section of pipe. The customer was very grateful for my quick and efficient fix.
