Direct answer: Water System Guide is an independent research publisher. Content is selected for decision value and evidence quality, not for payment or partnership. The site does not accept payment for placement or rankings, discloses its publisher boundary on every page, and corrects errors with changes recorded.
Independence
- No manufacturer, dealer, installer, utility, or agency pays for placement, positioning, or rankings.
- Product-family pages are organized by documented scope and decision value, not by commercial relationship.
- A mention or absence of a brand is an editorial decision; current availability and dealer status are separate, verified questions.
Evidence and disclosure
- Every page follows the methodology: measured facts with sources and dates, derived recommendations labeled as conditional, and unknowns marked unknown.
- Water System Guide is not an installer, manufacturer, dealer, utility, or laboratory. Its publisher boundary is stated on every page.
- No unsupported provider, product, availability, price, certification, or treatment claim is published.
Corrections
- Errors reported are investigated against the evidence layer.
- Material corrections are published with the change recorded; pages carry effective and review dates.
- Readers can report issues through the contact path.
Local market coverage
Local water evidence and professional discovery publish market by market as evidence gates pass. During the current transition, Houston-specific content remains on WaterFiltrationHouston.com, the operator property, and is not duplicated here.
