Did you run antifreeze through the filter housing with the element removed when you winterized? If so, I expect the antifreeze only mixed a bit with the water in the housing, rather than forcing it all out. The diluted antifreeze would have a higher freezing point than the straight stuff.
Yes I did; I open the low point drain, dump the water heater and when those stop dripping, always took this canister off, pouring the water out, along with unscrewing the pump strainer which always holds a thimble-full of water. Since this canister always made a mess no matter what fluid was in it while unscrewing it full, everything got wiped clean and dry both Spring and Fall.
Forest River also does not have a great way to bypass the fresh water tank for winterizing. I just pour the antifreeze in and flush well when getting the pink stuff out, so the canister was always the first thing filled, and flushed through with volume of pink stuff used to do all the plumbing. This is roughly 3 gallons. We always use bottled water for drinking and cooking while traveling for a variety of reasons so dealing with winterizing this way no big deal. It takes maybe 3 tank flushes to clean it all out.
