Unless I am mistaken, most hot water heaters I have seen feed from the top of the tank. When you are using low point drains, you are draining water in the lines, not from the hot water tank. If you are using this method to drain water for winterizing, you could be setting yourself up for a problem. You may be leaving the hot water heater full of water. But I have been wrong once or maybe twice before!
