The odor you smell is most likely coming from the sink drain and not the water. Over time the plumbing beneath your sink, which is typically a u-shaped pipe, can collect debris and create an odor. If you smell an odor, fill a clean glass with tap water and smell the water in a separate room or outdoors. If the odor is no longer present, the odor is likely from the plumbing beneath your sink.
If the odor is not from the sink drain or the problem persists, please email Customer Service or call 949-459-6420.
