I began by thoroughly inspecting the kitchen drain to identify any blockages or issues. Using a drain snake, I carefully navigated through the pipes to dislodge any debris or obstructions. After ensuring the drain was clear, I flushed it with water to confirm the effectiveness of the cleaning. I then conducted a series of tests to verify that the drain was functioning properly and efficiently. This included checking for proper water flow and ensuring there were no leaks or unusual noises. The job was completed to ensure optimal performance and longevity of the kitchen drain system.
