that he didn't want my mom to use hot water when boiling water for pasta or whatever. He claimed that it was "stale" and "nasty" from sitting in the hot water heater for an extended period of time. Now, if I'm in a hurry, I'll use hot water to facilitate getting boiling water quicker when cooking. On the other hand, if I got time, I'll start with cold tap water, supposedly in the belief that it is somewhat cleaner. But after all these years, I still remember his concerns, and now I'm wondering if they were unfounded. Is there really any difference in how clean cold water straight from the pipe is compared to water that may have set in the water heater for an extended period of time? One could argue that the hot water killed off bacteria that would otherwise have been present, but of course that's a moot point when you consider it's going to be boiled anyway. Besides, there probably aren't many bacteria that would be killed in 120 to 130 degree water that wouldn't be present in ordinary tap water anyway... Just a random thought... I've always kind of wondered about this. Anyone? Oh, and I'm assuming that the water heater in question is not backed up with sediment. Of course that would be rather nasty...
