Evidence before recommendation.

Well-water decisions can affect health, plumbing and substantial household spending. Our standards are designed to make evidence, uncertainty and commercial relationships visible.

Our testing-first rule

We will not recommend treatment from a regional map, photograph or odor description alone. Content should guide readers toward appropriate testing whenever important information is missing.

Evidence labels

Hands-on: directly inspected or tested, with methods and dates.
Laboratory: supported by a linked report from an identified laboratory.
Certified claim: tied to a named certification and scope.
Specification review: assessed from current manufacturer documents.
Owner experience: clearly separated from controlled evidence.

Review criteria

Future reviews may consider contaminant fit, flow, capacity, pressure loss, certifications, warranty, installation, maintenance, lifecycle cost, support and important disqualifiers.

Commercial and affiliate policy

No products are currently promoted through affiliate links. If affiliate links are introduced later, the relationship will be disclosed before the first commercial link and on the relevant page.

Commercial relationships must not change the standards used to assess suitability. A product with no affiliate program may still be discussed or preferred where the evidence supports it.

Corrections and updates

Health-adjacent claims, public guidance, merchant terms and provider records can change. Material pages should show review dates, cite primary sources and provide a visible correction route.
