I do leave some antifreeze in the holding tanks just for the valve seals.
I'm apparently unique in that when I'm done winterizing, I de-winterize right away, which includes draining the pink stuff, and putting the water heater bypass back to the normal summer position. I can't see a reason not to do that.
So what keeps the outside of the valve seals from drying out?
Your concerned about keeping valve seals in the tanks wet but not the seals in all of your taps, shower(s) and toilet wet?
Seems a little odd to me......
From my experience, the anti freeze does not evaporate, maybe a little but not in a enclosed environment of a faucet valve or toilet valve. There will always be a small bit or a film on the rubber seals, valve body, etc... If you have ever gotten some on your hands ( propylene glycol, NOT the alcohol based stuff) you know your hands feels oily afterwards. I dont believe the seals would dry out
