Upon arrival, I conducted a thorough inspection of the hot water tank to identify the source of the leak. The leak was traced to a corroded connection at the tank's drain valve. I carefully drained the tank to ensure safety and prevent further water loss. Next, I replaced the corroded drain valve with a new one, ensuring all connections were secure and leak-proof. I also inspected the tank's anode rod, replacing it if necessary to prevent future corrosion. After reassembling the tank, I refilled it with water and tested for leaks. The tank was then restored to full operation, and I provided the homeowner with maintenance tips to prolong the tank's lifespan.
