Open the vent on the hot water heater and your low point water drains. The water will then drain from the heater. Or at least mine does.
Not sure why so many people want to reinvent the wheel. This is how I do it as well. Didn't cost me a penny.
Any sediment that might be in the tank would be flushed every few trips, as I drain the water heater every few trips. Also, when I drain my low points, I get several gallons of HOT water (steaming hot) that drains from by low point. That's more than what would just be in the line. Its clearly draining the majority of the water heater.
Been doing this for 11 years. Never had any issue with a split water heater tank.
