I would have had your perspective except that a few months ago I came back from vacation to find that my hot water smelled like windex. The apartment complex flushed my hot water tank, a whole lot of black sludge came out, and my water has been fine since. I assume that not using the hot water for a few weeks caused everything to collect in a concentration high enough to notice, but it makes me cringe to think of how much low level of windex-smelling stuff I drank previously. (Fortunately my hot water takes a minute or two to arrive, so I probably didn’t consume that much just because I didn’t want to wait long enough.)
