What 1959 tells you about the pipe in Columbia
Housing of this vintage generally means galvanized steel still the norm, with copper appearing towards the end of the decade. A house from these years may have had part of its supply replaced and part left alone, which is why pressure can be fine in one bathroom and poor in another. More on 1950s supply pipe.
64% of occupied homes in Columbia are owner-occupied, 14 points below the PA 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 Columbia ZIP codes is $61,130, 35% below the PA median of $94,450.
Before calling anyone in Columbia, 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.
