What 1968 tells you about the pipe in Bethesda
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.
70% of occupied homes in Bethesda are owner-occupied, 14 points below the MD figure of 84%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Bethesda ZIP codes is $231,284, 94% above the MD median of $119,156.
Before calling anyone in Bethesda, 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.
