I've got a Tab 320s and have been traveling across country mostly drinking bottled water. I use tap water to make coffee in the mornings and never noticed any issues. At my sister's house now and noticing that the coffee smells faintly of plastic, and tried drinking water out of the tap and it too smells of plastic. I know I should disconnect the hose and try water from that to see whether the issue is inside or outside the Tab, so will do that. It has been quite hot here (upper 90s) and the Tab is sitting on concrete, as is the hose, and probably for the longest period of the trip, but otherwise, nothing has changed. I have flushed the freshwater tank (and faucets) now with bleach mixture 2x this season. Not sure what else I should do. Has anyone else encountered this issue?
