What 1948 tells you about the pipe in Mountain Lakes
Housing of this vintage generally means galvanized steel as standard, and at this age the inside diameter of a half-inch line can be materially narrower than it was when it was fitted. The classic sign is that pressure is worst at the fixtures furthest from where the water comes in. More on 1940s supply pipe.
97% of occupied homes in Mountain Lakes are owner-occupied, 20 points above the NJ figure of 77%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Before calling anyone in Mountain Lakes, 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.
