The short answer
Housing in Moraga runs to a median build year of 1972. Pipe of that era fails in more than one way, so the useful first step is counting weak taps: every tap points at the supply, one tap points at that fixture.

Moraga has 5,682 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1972 — 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.Moraga sits 1 year newer than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 49% of them, and by number of homes it ranks 207th.
What 1972 tells you about the pipe in Moraga
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.
84% of occupied homes in Moraga are owner-occupied, 32 points above the CA figure of 53%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

The first thing to establish in Moraga is whether the problem is the house or one fixture, and it takes two minutes of walking around. Housing of this era can be copper throughout or copper with polybutylene in part, and the two fail differently enough that the pattern matters. Normal is 45–80 psi, under 40 psi is low — test it. Whole house is a call; one tap usually is not.
