Municipal accounting lives for plumbing (D20)
14 municipal policies from Ontario set a life for plumbing as a whole, from 10 distinct tables: 15–50 years, median 26.3. These are amortization periods chosen for accounting, not measured lives, and they describe the system rather than this component.
Years. Each dot is one stated life and each bar a stated range; equal values stack. 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.
- No preventive maintenance tasks are sourced yet.
