I have a 2009 Landmark Agusta and since day one, we've had terrible tasting water. At first, I just thought it was because it was new and the foul taste would go away away! No Luck. Six months later and many RV parks, water filters, and several visits to the dealer later, the taste remains. The taste is in ALL water points, etc. ice maker, both sinks and shower. Heartland and dealer say they've NEVER had such a problem or heard of such a problem. Has anyone else experienced this situation and if so, how did you correct? We've tried bleach and water treatment tablets. HELP!!!
