For this job, the toilet fill valve was replaced due to its age and overall condition, and the flush tower was also replaced because it was worn and no longer holding water in the tank. After installation, the toilet was tested through multiple flush cycles to verify proper filling and flushing, with no leaks observed. The customer is ordering the new kitchen faucet and lavatory faucet, which will be installed at a later date. At the time of completion, all serviced components were tested, found to be operating as they should, and no leaks were present.
