Mine has an upper and lower cut-off. Thanks
Welcome to the forum. I would think you have to turn both to isolate the water heater. Did you have the plug/anode out while winterizing? If not the tank may have some antifreeze in it. If you had the plug/anode out, did antifreeze come from that location? Once the water heater is isolated it should not take much antifreeze other than just filling the lines like the cold water side did.
