Has anybody had experience with hot water tank leaks on Hunter? I emptied the tank last fall, bypassed the tank externally, and filled lines with anti-freeze. Spring time, I reconnected and filled with water. Now, the water pump runs every couple of minutes. If I bypass the tank, the water pump does not leak. Fairly sure water is collecting, so fresh water leak appears to be the problem. So the question is, has anybody had experience with leaking tanks. Do I need to remove tank, or can covers be removed to reveal likely failure mechanisms? Hoping it is just a fitting, or other. Thanks for any input.
