You measure a static street pressure of 95 psi at a new residence. According to the code, what is required on the water supply?

When static water pressure exceeds 80 psi, the code requires an approved pressure regulator to reduce downstream pressure to 80 psi or less. Doing nothing is wrong because 95 psi exceeds the 80 psi limit; a larger meter does not reduce pressure, and per-fixture check valves are not the code remedy for excessive pressure.
