Terms of Use — Estimates Provided As-Is

Acceptance

By using Water Softener Size Calculator you agree to these terms. If you disagree, please don't use the site.

The calculators provide estimates

Every output — grain capacity, market tier, regeneration cycle, salt use — is an informational estimate built from industry-standard sizing conventions and your declared inputs. They are not engineering advice, not a water treatment prescription, and not a substitute for a water test or a licensed professional where one is warranted (commercial systems in particular).

Content licensing

Article text and the formula write-ups are copyrighted with standard attribution rights: quote with a link. The formula constants themselves (unit conversions, the USGS scale) are public knowledge — cite the primary sources we cite, not us.

Brand names

Manufacturer and brand names are trademarks of their respective owners, used here for identification and comparison under nominative fair use. No affiliation or endorsement is implied — the opposite, in fact: this site exists because brand-owned sizing tools don't compare across brands.

Affiliate disclosure

Where present, retailer links may be affiliate links that earn us a commission on purchases at no cost to you. Commissions never influence a specification, a table row or a calculator result — the about page documents how every number is produced.

No warranty

Content is provided "as is" without warranty of any kind. Water chemistry, product lineups and official specifications change; every page carries its verification date, and the linked official source always governs over our summary of it.
