Plan home water filtration from test results, flow and pressure needs, system placement, maintenance, and verified treatment goals.
Choose a treatment system only after defining the water problem and the demand it must serve. Well owners should begin with the well-water test panel guide
; a screen or TDS reading cannot identify every contaminant. For a whole-house system, calculate flow-rate requirements
before choosing housing, media, or cartridge size.
Pressure and maintenance are separate design checks. Use the low-pressure diagnosis checklist
and filter-bypass guide
before blaming the treatment media. For drinking-water reverse osmosis, the RO buying guide
explains the system decision, while the RO waste-water ratio guide
explains how product-to-drain ratios should be read. These guides do not treat filtration, softening, conditioning, and disinfection as interchangeable.
Build a stage-specific RO prefilter service record, distinguish restriction from disinfectant breakthrough and verify restart conditions without generic PSI rules.
Use a sampling-purpose matrix to order a useful well-water panel, choose raw or treated sampling points, check reporting limits and avoid invalid collection timing.
Calculate brine-tank salt storage from dose per regeneration, expected cycles and an explicit reserve, then check approved fill limits and refill access.
Build a hard-water purchase brief with measured hardness, treatment outcome and installation constraints before comparing softeners, conditioners or filters.
