Upon completing the inspection of the washing machine shut-off, I observed that the packing nut was loose. This looseness was likely contributing to a leak that had been present. I promptly tightened the packing nut, which successfully halted the leak. However, upon closer examination, the packing nut appeared to be heavily corroded, indicating that it might not last long under continued use. To address this issue, I provided a detailed quote for replacing the packing nut. The client reviewed the situation and confirmed that no other issues were present. With the leak resolved and the client satisfied, we concluded the service successfully.
