I bought the sink from Home Depot and put it in. I smelled this acitic odor every time I opened the drawer od cabinet door that made me walk away from the sink. I thought it may be as bad vent pipe or stinky drain pipe. After replacing 2 vents and all the plumbing in haldf the house I finally concluded that it was the sound undercoating on the sink (MADE IN CHINA), that smelled so bad. So I called Elkay and they sent me another sink, put it in and the same thing happened. I stunk too. I called them again. I have spent thousands of dollars trying to fix this to ao avail. I guess I keep asking for a new sink until they send me one that dosn't sting.
