What 1970 tells you about the pipe in Ronkonkoma
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.
76% of occupied homes in Ronkonkoma are owner-occupied, 29 points above the NY figure of 46%. 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 Ronkonkoma 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.
