I responded to a service call at the customer’s home regarding a toilet that wouldn’t stop running. After diagnosing the issue, I found that the fill valve had failed and the existing supply line was also worn and due for replacement. I removed the faulty components and installed a new fill valve and a reinforced supply line. After installation, I tested the toilet multiple times to ensure proper operation. The toilet is now functioning correctly with no signs of leaking or continuous running. Customer was satisfied with the repair and the issue has been fully resolved.
