I have a whirlpool side by side refrigerator with an ice maker / water dispenser in the door. I got it used and have never use the water features because there is a peppery taste in the water that sits in the line for a while. I have tried the water in the supply line and have ruled that out. I have replaced the filter to no avail. if I purge the water, I can use it without the taste but if I let it sit, say.. over night, the peppery taste comes back. Both water and ice have problem.
I have a theory that pepper containing food was stored in the refrigerator and the aromatics leech into the internal supply lines, thus contaminating the water.
Does this theory seem valid? Has anyone else had this problem? Has anyone else solved this?
I am thinking about running copper lines to replace the internals.. Any advice?
