A good thing to do in an older house where some lead may exist in the plumbing is to run the water for a minute before getting water for consumption by infants and young children. And to use cold water only for preparing food for children as the water in the water heater is stagnant compared to the cold water. i.e Use cold water to make soup that children will consume, don’t use hot water to make the soup.

None of that is needed in a modern home with lead-free or PVC pipe and connectors...although some feel that it is still a good idea.

We will have a fridge with a filter, and will put one on the sink for cold water, primarily because the water where we live tastes like crap without a filter of some sort. Not too worried about hot water, as it always runs for a while to get hot, and then more so to wash anything. We don't use hot tap water for any food prep.
