MAINTENANCE & WARRANTY
A system that needs a $1,000 replacement every two years is a different purchase from one that runs ten years with a $40 sediment filter. FilterTier puts that difference up front.
REPLACEMENT REALITY
Replacement interval, cartridge price, pack size and how dirty source water can change the schedule.
Years and gallons, whether the tank is replaced or re-bedded, and the current media cost.
Certified capacity, replacement price and whether multiple cartridges are installed in parallel.
Annual lamp replacement, sleeve cleaning and replacement schedule, plus the UV system's flow rating.
Expected salt use, regeneration water, resin life and whether professional re-bedding is likely.
Required inspections, labor, travel, proprietary parts and whether DIY maintenance affects warranty.
SIGNATURE METRIC
Equipment + scheduled consumables + major media replacements + salt + UV + published/estimated service assumptions, with the assumptions shown.
WARRANTY REALITY
Term, prorating and exclusions.
Often shorter than the tank warranty.
Controllers, monitors, power supplies and smart features.
Defect coverage versus performance/capacity guarantees.
Whether the manufacturer or dealer pays to actually fix it.
Whether warranty follows the home, new owner or only the original purchaser.
Deadlines, proof of purchase and installer registration requirements.
Filter changes, salt use, service records and water chemistry requirements.
Who pays to ship a failed tank, valve or component.
THE FINDER USES THIS DATA
If you say you want minimal maintenance and a 10+ year warranty, FilterTier should not quietly recommend a system with two-year major media replacements and a short warranty just because its filtration score is high.
Minimal maintenance · major replacement 5–10 years · 10+ year warranty desired
Long-life high-flow systems gain fit points; short-life systems remain visible but explain the mismatch.

FilterTier provides independent comparison and educational information, not medical, plumbing, engineering or legal advice. Product claims, certifications, specifications, prices, warranties and availability can change; verify current details with the manufacturer and use water testing and a qualified professional when appropriate.
