I can empathize . I'm in a high-rise apartment building not all that far away fom you. We are a family of 4, including 2 grown children, one of whom has multiple challenges . I have a large soaking tub and a good sealing strategy for GP wash up / toilet flush. For drinking, bottled water. I also have to refill my 8 5gal. plastic water cans. In the mean time, I have bottled water, with backup purification supplied by a General Ecology, First Need Deluxe, hand pump purifier. Semi old tech, but none better. Purifies everything, slowly, with effort, no max shelf life on filter to worry about.
