Hi, I purchased a Whirlpool side by side fridge at the end of May (this year). The control panel said it was time to change the water filter so I did. The water tasted great prior to changing the filter. After I changed it, the water tasted terrible. I flushed it with 3 gallons, as indicated in the directions. then an additional 2 gallons when I saw it still tasted bad. so, I thought it was a bad filter. I bought another new one today, flushed with 3 gallons and it tasted fine. But, then when I went back an hour later, it tasted bad again. Flushed another gallon or so, it tasted fine. another hour later, its bad again. what is going on? I would suspect the reservoir or the lines, but, it was all fine before I changed the filter which leads me to believe it's that. Any advice?
Thanks!
