A couple things come to mind.

1. Even though you've set the overall reflectivity high, the BRDF values are not set high enough for such a reflective surface. They control how reflective the surface will appear based on the angle of view, and chrome is pretty reflective from all angles, so instead of having a 0 degree value of 0.2(default) you can bump that up to near the full 1.0


2. The normals on the drawer handles could need reversing as they are not even showing any kind of reflection like the faucet is doing.
