Query: Water tastes like plastic

DO NOT BUY THIS COOLER - it makes the water taste bad, like plastic. I have "flushed" the cooler with more than 6 gallons of boiling water as instructed by Ice Mountain, and that fixes the "plastic" taste for about 2 days. Then the taste slowly starts to come back, and by the 5th day after the flush it's back with a vengeance - worse than it was before! No point in buying bottled water if the cooler is going to make it taste awful!
