Antifreeze in water pump

I have what I think is an unusual question. Search didn't help. I live in west TX, and we have mild winters. Might go down into the teens for a few nights, but nothing real crazy or long. I have several friends here that use the air adapters to blow out water lines, and they have never had a problem. We are intending on using the camper some even throughout the winter, so I really don't want to pump everything with antifreeze between every trip. All winter trips will be to campgrounds with hookups, no dry camping. I'm getting ready to winterize the rig this weekend and have a question.

Can I pump antifreeze through the water pump to fill it, then still use the camper on city water? I know after the initial fill I will have to flush out the antifreeze that got past the check valve, but once that is done shouldn't I be able to safely use the rest of the water system on city water while the pump stays full of AF?

I am trying to make it so that after every trip its a quick process of blow out lines, drain water heater, and antifreeze in the drain traps.

I am 60 miles south of Dallas. We get weather like you are describing at times. If we know it will freeze for a few day or if we will not be using the RV for several weeks this time of year I'll blow out the lines, outside shower and toilet included. Remove the water filter and the strainer bowl from the water pump. I'll bump the pump a time or two and a quart or two of the pink stuff in the traps. In over 5 years never a problem
