UFC 3-420-01 (current as of 2021-04-01) is a Unified Facilities Criteria document on Plumbing Systems [UFC 3-420-01]. However, the passages provided contain only the document's cover page, record of changes, references section, and glossary reference—not the actual technical criteria or design requirements.
The document itself was cancelled as of the 2021-04-01 version, superseding the previous edition dated 25 October 2004 with Change 10 [UFC 3-420-01]. It is referenced by Air Force publications as the governing standard for plumbing system design: DAFMAN 10-246 requires water and plumbing systems be "designed and constructed in accordance with UFC 3-420-01" [DAFMAN 10-246 para 2.4.4], and DAFMAN 32-1067 similarly mandates design in accordance with this UFC [DAFMAN 32-1067 para 4.2.1].
For specific technical requirements from UFC 3-420-01 itself, the indexed passages do not contain substantive design guidance—only administrative and reference materials.
