A lot of people find that bladder tanks for drinking water
give it a sort of "plasticky" taste. Bladder tanks for waste holding, by their nature, do not allow the proliferation of aerobic bacteria that is needed to control odors. Hence, they contribute to the stinky head
Personally, I would never consider a bladder holding tank
I would also not use a bladder for my "normal" drinking water
. I might consider it as a supplementary tank when I was going to be away from fresh water
sources for a long time, and wanted to carry a larger than normal amount of drinking water.
