I successfully completed a hot water tank flush, ensuring optimal performance and efficiency. During the process, I thoroughly inspected the flue pipe and identified signs of wear and potential safety hazards. Based on my assessment, I recommended replacing the existing flue pipe to prevent any future issues. I then installed the new flue pipe, ensuring it was properly aligned and securely attached to the tank. This crucial step enhances the safety and functionality of the hot water system. Additionally, I checked for any leaks or damage and made necessary adjustments to guarantee a leak-free operation.
