Service life

50 yearsas stated by one source
0510152025303540455055605050

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, p9). Treat it as that source's figure, not a settled life, until others confirm it.

Basis

  • 50 years · CNA e-Tool Estimated Useful Life Table, p9 · HUD CNA 3.4.1.1.7 “Sewage Ejectors” — 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

  • HUD's 50 years for sewage ejectors may describe the basin and piping rather than the pump. Pump lives need a second source.
  • Only one source so far: HUD planning lives for US multifamily housing. Canadian and observed sources are needed.
  • Some maintenance intervals come from TM 5-692-1, an Army manual for mission-critical (C4ISR) facilities; they may be tighter than typical commercial practice.
