Upon arrival, I discovered water leaking through the ceiling. To locate the source, I cut an access opening in the ceiling and informed the customer that drywall repair was not included in the service. After gaining access, I identified a leaking 90-degree fitting as the cause. I carefully repaired the fitting, ensuring all connections were secure and leak-free. Following the repair, I tested the system thoroughly to confirm that no further leaks were present. The issue was successfully resolved, and the customer was satisfied with the outcome.
