Editorial Policy

Resin Ledger exists to help homeowners make water softener decisions from traceable evidence. We prioritize usefulness, accuracy, model-specific boundaries, and transparent uncertainty over search traffic, word count, advertising opportunities, or commercial relationships.

Sources

We prefer primary and authoritative sources: government guidance, official standards information, live certification databases, manufacturer performance sheets, and exact model manuals. Important numerical or safety-related claims should identify their source and consultation date.

Secondary sources may help identify a question but do not replace the primary source when one is reasonably available. We do not copy retailer descriptions, forum settings, or a similar model's instructions into a universal recommendation.

Calculations and original resources

Calculators must publish their formulas, units, assumptions, validation cases, error states, and limitations. Worksheets and comparison tables distinguish source values from calculated values and user-entered values. Unknown values stay blank.

Authorship and review

Articles are published under the Resin Ledger name, without personal bylines. We do not attach a person's name, credentials, or a "reviewed by" label to a page unless that person reviewed that exact version and the date, scope, and findings are recorded.

Every number, safety limit, and model-specific instruction is logged against its source and the date it was checked. Pages that cover controller settings, performance data, sizing formulas, maintenance chemicals, or service decisions state their limits and point to the manufacturer manual or a qualified professional where the answer depends on the exact model or installation.

AI-assisted work

We may use AI-assisted tools for research organization, outlining, drafting, consistency checks, metadata, and calculation QA. AI does not perform physical testing, hold professional credentials, inspect an installation, or replace accountable human review. We disclose the process where a reader would reasonably expect to know how the material was produced.

Commercial independence

Advertising, affiliate compensation, sponsorships, samples, or business relationships do not buy a favorable conclusion or remove a safety limitation. Material connections are disclosed clearly and close to the relevant endorsement or link. Paid placement is not presented as editorial ranking.

Updates and corrections

Pages carry publication and substantive review dates. Dates are changed only when the content receives meaningful review or revision. Correction requests follow our Corrections Policy. Material corrections describe what changed and when.

What we will not publish

• fabricated tests, ownership, quotations, credentials, reviews, or measurements;
• a model setting or procedure generalized without evidence;
• a certification claim that cannot be matched to an exact current listing;
• a health, potability, contaminant-removal, savings, or lifespan guarantee;
• copied or lightly rewritten content created mainly to display ads;
• internal electrical, pressurized valve, or plumbing repair presented as generic owner guidance; or
• content that cannot pass its assigned safety or technical review.
