What 1984 tells you about the pipe in Great Falls
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.
95% of occupied homes in Great Falls are owner-occupied, 15 points above the VA figure of 80%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Before calling anyone in Great Falls, 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.
