Hi Doc, Are you sure your 23SS doesn't have the check valve. I have the same set-up shown in the pictures above and on my first attempt at winterizing the antifreeze was getting past the check valve and coming out of the water heater. The hose kept slipping out of the antifreeze so I can only assume the air mixed with antifreeze wasn't building up enough pressure against the check valve. I tried the process again with water and it worked fine and then with antifreeze and it worked fine again.
Just glad I didn't need to start cutting and add another valve if I didn't need to.
