When winterizing, I remove the filter from the clear housing, and trash it. I then fill the clear housing with clean, washed pea gravel, which I keep specifically for this purpose (the same gravel every year). That way, I'm not having to fill that housing with antifreeze. Same principle as a hot-water bypass, only on a smaller scale. As previously mentioned, I'm just barely able to get by with a single gallon of AF.
I know, AF is cheap. But so am I.
Anyway, new filter goes in the next spring. They are only $10 for 2 at Walmart. The 2nd filter goes in a ziplock for next year.
