Service life
Years in service. One stated life so far; the band will widen as sources are added.
One source. This value rests on a single document (CNA e-Tool Estimated Useful Life Table, p11). Treat it as that source's figure, not a settled life, until others confirm it.
Basis
- 40 years · CNA e-Tool Estimated Useful Life Table, p11 · HUD CNA 3.4.1.3.5 “Toilets/bidets/urinals” — U.S. Department of Housing and Urban Development (planning life)Same life for family and elderly properties. US multifamily housing.

Municipal lives for plumbing (D20)
26 municipalities in Ontario and British Columbia state a life for plumbing as a whole, in 18 distinct tables: 15–50 years, median 25. 34 rows come from capital asset policies (accounting lives, used for amortization) and 1 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.

Open questions
- Only one source so far: HUD planning lives for US multifamily housing. Canadian and observed sources are needed.
- Aimed at water efficiency in federal facilities, not full fixture maintenance.
