Responded to an emergency sink drain issue after the customer noticed water leaking beneath the kitchen sink and pooling inside the cabinet. The plumbing was inspected to identify the source of the leak, including the drain connections, fittings, and surrounding pipework. Damaged and worn components were removed and replaced with properly sized drain fittings. The new connections were carefully aligned and securely tightened to help prevent future leaks. After completing the repair, the sink was filled and drained several times while the entire assembly was checked for leaks and proper water flow. The repair restored normal drainage and helped protect thecabinet and surrounding area from additional water damage. Customer was advised to monitor the connections for any changes.
