Maybe I am too stupid to understand... what is the benefit of immediately draining the antifreeze after running it through?
If your Pex lines are retaining the taste of the antifreeze, you need to replace your lines. They should not absorb, and if they are absorbing the taste of the antifreeze they are also absorbing bacteria from the water and will make you sick.
lets see, option A, replace all lines, complex and horribly expensive; option B, drain antifreeze, cheap and easy. I'll Take Door Number B.
bacteria may form a biofilm on the plastic piping but absorbing them, I don't think so. but a standard sanitization should fix that.
