I understand it is a draw, but multiple posts here have said to skip it if on a well(which I am). Is that because well water is generally harder on the filter mechanics?

My other thought was to do an outdoor barrel sauna, and/or a stock tank pool for the hotter months. My place is a cabin in the mountains so a stock tank pool would fit the vibe. But if those have to be dumped every week like a hot tub, maybe not.
