The short answer

The median build year in Marion is 1979, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.

Sources: US Census Bureau, American Community Survey 5-year estimates, table B25035; normal and low ranges as published by Grundfos in its homeowner guide to low water pressure.

Marion has 5,334 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1979 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

What this site is

PressureTrace is a referral service, not a plumbing contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We do not perform plumbing work, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

Marion sits 12 years older than the SC median of 1991. Of the 77 SC towns we route calls in, its housing is older than 92% of them, and by number of homes it ranks 36th.

What 1979 tells you about the pipe in Marion

Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.

58% of occupied homes in Marion are owner-occupied, 14 points below the SC figure of 73%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Median household income across Marion ZIP codes is $35,340, 46% below the SC median of $65,603.

In Marion, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
