Byline
Tim Parker
Every verdict on this site carries this byline. There is no certification, membership, or lab affiliation behind it — the authority is the published method, not a claimed credential.
Tim Parker writes the reviews, comparisons, and buying guides published on AquaVerdict. The job is the same on every page: pull the manufacturer's published specs — media life in gallons, service flow in GPM, certification scope, street price — and price out what the system actually costs installed, not what it costs on the box.
No claimed credentials
AquaVerdict does not attach a certification, a professional license, a lab affiliation, or a years-in-the-trade claim to this byline, because none of those things back the work that actually happens on this site: reading spec sheets, checking NSF listings against the manufacturer's own claims, and doing the installed-cost math. If a fact needs a credential to be true, it belongs in the article as a cited primary source — EPA, NSF, or the manufacturer's own documentation — not as a claim about the author.
How the verdicts are actually built
Every review and comparison on this site follows the same five-checkpoint method — true capacity, flow honesty, certification scope, all-in 10-year cost, and failure modes. It is fully documented, including what happens when a manufacturer will not publish a number we need. Read the complete methodology on How We Evaluate.
Affiliate relationships are disclosed separately and do not influence scores — see the affiliate disclosure page. SKIP and “it depends” verdicts on commissionable products are the evidence for that claim.
