Imeo, not much, just a thought,
I noticed that the O-rings that we're using for the AVS, when in contact with the liquid, start to leave black traces on the liquid, that then mixes up with the liquid inside the tank.
Of course, it is always recommended to clean AVS parts with water each time we refill the tank, but for those who use a single fill up, over 2 or 3 days, they might have black traces in their liquid, before even finishing that fill up.
Are there types of O-rings that do not leave traces? Blue or white or orange types of O-rings for example? Who cares about the color anyway, since they're hidden now.
