The short answer
The median build year in Porter Ranch is 1980, 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.
Porter Ranch has 12,948 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1980 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

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.Porter Ranch sits 9 years newer than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 27% of them, and by number of homes it ranks 144th.
What 1980 tells you about the pipe in Porter Ranch
Housing of this vintage generally means copper throughout in most cases, with polybutylene fitted in some homes built from the late seventies onward. Polybutylene was discontinued in the mid-nineties and is worth identifying, because its failures are sudden rather than gradual. More on 1980s supply pipe.

In Porter Ranch, 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.
