Whole House Water System Planner
A browser-based planner that helps homeowners size water treatment, estimate flow needs, sequence equipment, and compare ownership costs before buying.
Field notes
The interface separates municipal and private-well inputs, then asks for evidence quality alongside hardness, iron, manganese, pH, flow, and household-use figures. Users can select a 10%, 20%, or 30% planning reserve and receive checks that include USGS hardness classification, a whole-house flow target, treatment order, certification fit, and ownership considerations. The site also provides linked calculators for regeneration intervals, annual salt use, efficiency, and ten-year cost, with utility CCRs and certified laboratory results treated as stronger evidence than estimates.
