I have a 3300RCB and this will be the first winter.
I plan on closing the by pass valves on the hot water heater and draining the heater and will leave the anodized rod out.
Then do the antifreeze thru all the water lines till I see pink out of all the faucets, put some in each drain.
Is there anything to do to the city water hookup and the black water flush?
Thanks
Dan

YES, make sure the city drain is opened and use air to blow out the black tank flush system.(I learned that the hard way.)
