I would agree. When I blew my system out there was still a pool of water in the filter when I took it off. I took a rag and dabbed it up.
Also in my manual it says to take the hose off the end going out of the pump and run the pump briefly to drain out the water. If you blow it out well there won’t be much left. But it is easy for the pump to retain water and freeze.
Also you must be very careful to get out all the water in the toilet lines. This takes a while. I had to shut off the toilet briefly while under pressure and flush about 10 times before no more water was coming out. Should that water remain it will most definitely freeze.
This is why I put in antifreeze. I blow out the system, but just feel more secure with antifreeze there. Better to not take chances than to have a mess in the Spring. Some suggest to blow out the antifreeze as well when you are done putting it through.
I would suggest getting a bypass installed (which you may already have since you have a 2020) so that you can pump antifreeze through the system. It is easy. Doesn’t take long and come Spring it really takes no time to clean it out.
This whole winterizing gets easier the next year.
Also don’t forget the outside shower. Often overlooked.
