The short answer

What 1963 tells you about the pipe in Great River
Housing of this vintage generally means the changeover years. Copper is common by now but galvanized is still in the ground and in the walls, so what matters is not the build year but which sections were ever replaced. A pressure test at the outside tap tells you more than the age does. More on 1960s supply pipe.
96% of occupied homes in Great River are owner-occupied, 49 points above the NY figure of 46%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
