I just realized that there's one more step to winterizing that I've never seen posted anywhere.? If you have low point drain valves in your plumbing, there's about 1.5 ft of pipe that goes to the drain.? So with the water pump enabled, you need to open the low point valve for a couple seconds.? That will replace water in the drain line with antifreeze.
?
Pex pipes can supposedly freeze 400 times without damage, however.? So if you dont do this last step, you probably won't have any damage.
