The odor permeates all the other cabinets as well and it also is coming up from the drain itself. I have asthma and am very allergic to chemicals. Since it was installed about three weeks ago, I have had an upper respiratory infection along with laryngitis. I have asked the plumber if he used any petroleum products since that is how it smell, more or less. Can anyone help me to get rid of this? Even my family has smelled the odor and all agree that it is a chemical smell.
