As of January 1st, 2025 we will be amending our water meter sizing standards to more closely align with the 2023 Oregon Plumbing Specialty Code. Fixture unit loading values will not change from previous evaluation methods, but the determination of minimum size requirements will now be based off of the full scope of Table 610.4. Meter and Building supply sizing will be based directly off of the respective columns, as written in table 610.4.
