Methodology & sources
National range is an editorial estimate from durable historical cost data; treat as a rough planning number and verify with local quotes.
State adjustment uses an editorial labor-cost index (0.85–1.35 vs national average) — a simplification of real regional variation.
Quality tiers apply published multipliers for material/type differences (Basic pedestal / Standard submersible / Submersible + battery backup).
Ranges exclude financing, unusual site conditions, and code-upgrade surprises.
