Winterizing Hot Water
So, I am getting ready to winterize my water system, and was wondering...
If I start pumping the antifreeze through the lines, naturally it will get pumped through the water heater, right?
Well, then I got to thinking, since there is water in there already, when the antifreeze starts circulating through the water heater tank, won't it be diluted by the water already there and essentially becoming not that effective at preventing freezeups?
So, what do you all do? Do I drain the water heater? And if I do, then when I circulate antifreeze, it will be circulated through an empty tank, and then I would have to fill it with antifreeze anyway. I know of no way to prevent the water from pumping through the (now empty) tank, so I am left with the same problem as when it was full of water!
