Upon arrival today, I evaluate the master bathroom sink, plumbing. Both sinks required replacement of the hot and cold supply stops, totaling four supply stops in the master bathroom. The existing shut off valves were aged, and showing signs of where, which can lead to a restricted operation or potential leakage. After reviewing the findings and options, the customer elected to move forward with replacing all four supply stops today. All new supply stops were installed, connections were inspected, and the system was tested at the fixtures. At this time, everything is operating properly with no visible leaks.
