What 1963 tells you about the pipe in Markham
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.
73% of occupied homes in Markham are owner-occupied, 5 points below the IL figure of 78%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Markham ZIP codes is $53,059, 42% below the IL median of $91,306.
Before calling anyone in Markham, check whether every tap is weak or just one. Normal supply is 45–80 psi and under 40 psi is low — how to test it in a minute. Whole house is a supply problem worth a call; one tap is usually a five-minute job you can do yourself.
