Any advice would be greatly appreciated
Not sure How to drain the newer unit's fresh water tank older units had a fresh water drain under the tank.
But I can tell you opening the low point drain will not drain the fresh water tank. If their is no Fresh Water drain you will need to turn on your pump and leave low point drains open. But I sure their is a drain under the tank!
