Those of you with accumulator/pressure tanks

I'm going to add one to my camper. My only question is what do you do to winterize? I have always just blown air through my lines and dumped RV antifreeze down the drains. Will I need to start running the antifreeze through my lines as well?

I put a T valve on ours when we had one. Then I could empty out the last bit of water in it.

I have a valve at the tank that I close after expelling the water then I can pump the antifreeze into the water lines.

The tank should be a bladder type with air on top, water on the bottom. Once you open the low point drains the air pressure should expel the water.
