Inspect Existing Supply Line for Damage

What happens here

Carefully inspect the flexible supply line connected to the faucet, paying close attention to the metal connector nuts and the braided hose itself. Look for any visible cracks on the nuts, particularly where they connect to the fixture or the shut-off valve. Also, check for discoloration, rust, or fraying on the braided exterior of the hose, as these are signs of degradation and potential future leaks. The video shows a nut cracked completely through and rust spots on the hose.

Goal: Examine the existing braided flexible water supply line for signs of damage, such as a cracked connector nut or corrosion on the hose. Even without an active leak, these issues indicate a potential failure point.
