I just recently moved into a home in Northern California and had actually been seeing a musty odor beneath the cooking area sink. It appeared like there was an older past water leak evaluating from a slightly warped thin piece of wood on the bottom of the cabinet, so I let it air out and it seemed to improve. A couple of weeks later inspected once again because the odor had returned and finally saw a TINY leakage coming from where the pipes trap connects. It was not really safe so I tightened it well and after that cleaned and decontaminated whatever. I likewise put a container of Arm & Hammer Wetness absorber (comparable system to Damprid) just to catch any remaining wetness in the air.
