Editorial Policy
Grayfield covers pipe materials that can contaminate a tap or cost a household five figures to tear out. Standards that consequential belong where anyone can read them, so here they are in full. The people behind the site and the way it stays funded live on the about page; what follows is the working method.
Which sources outrank which
Evidence is ranked, and the ranking does not bend for convenience. Federal agencies sit at the top: the Environmental Protection Agency for drinking water limits, service line inventories, and replacement deadlines, and the Centers for Disease Control and Prevention for exposure guidance. Beneath them sit state plumbing codes and the replacement programs run by municipalities and water utilities, read off the agency's own page rather than a news summary of it. Anything touching litigation is taken from the docket or from notices issued by an official settlement administrator. Cost marketplaces such as Angi and HomeGuide occupy the bottom rung and serve one purpose only, pricing, named on the page and stamped with the year of the data.
No orphan numbers
A figure that arrives without a parent gets cut. Pipe lifespans, repipe cost bands, lead action levels, program deadlines: whichever body published the number is named in the same sentence, so a reader can go and check rather than take an impression on faith. Nothing here hides behind "experts say" or "studies show." Prices run as ranges instead of one comfortable average, and every range declares which year it describes, because repipe quotes move with copper and labor.
The line we hold on lead
Lead is the heaviest subject on this site, so health wording stops precisely where the agencies stop. Zero is the number EPA holds as its maximum contaminant level goal, the health target for lead in drinking water. In children, CDC has identified no blood lead level that can be called safe. Pages carry those positions and add nothing to them. What no page will tell you is how much lead is in your body, what a test result means, or what treatment to pursue. That work belongs to a physician and a certified laboratory, and readers get pointed to both instead of to a guess.
Closed cases stay labeled closed
Polybutylene and Kitec each ended in a large class settlement, and the claim windows for both have shut. Pages say so outright rather than leaving a hint that money might still be sitting there, because a homeowner who believes otherwise burns weeks chasing it. Litigation detail comes from court records or the settlement administrator, never from forum threads, contractor blogs, or firms shopping for plaintiffs.
Machines draft, people decide
Drafting here is AI-assisted, and saying it outright beats burying it. Software writes the first version. A human editor then rules on what stays, re-checks every figure against the body that published it, holds each health sentence against agency language, and deletes whatever cannot be confirmed. No invented experts appear on this site, and no fabricated licenses, awards, or years in business. Pages run under a team byline because a team is what actually stands behind them, and nobody is dreamed up to sign work they never did. Pictures on these pages are generated, not shot on assignment, and their IPTC metadata says so in machine readable form. Each one is captioned for what it actually depicts, and none of them is offered as a job carried out by Grayfield or by any partner plumber.
Telling us we got it wrong
Corrections land on the page itself, not in a note nobody scrolls to. Three things make a report usable: the address of the page, the sentence you dispute, and the source that contradicts it. Send them by way of the contact page, or write to hello@grayfieldhome.com. Verified errors are repaired quickly, and a substantive repair moves the page's updated date.
What the datestamps mean
A publish date marks the day a page first appeared in public. A second date, the updated one, gets added strictly after substance moved: a rule changed, pricing was re-checked, an error was repaired. Dates never get rolled forward to imitate freshness. One boundary belongs in the open alongside them: nothing published on this site is medical, legal, insurance, or financial advice.
Where the revenue enters, and where it stops
Grayfield writes about pipe and never lays a hand on it: nothing on this site is sold, dug up, cut out, or repiped by the people who produce the pages. Dial (800) 555-0195 and the call travels through a partner network to a plumber working in your area, state licensed and insured, at any hour. A qualifying call can pay Grayfield a referral fee. That money moves between the network and this publication, nowhere near your job, and the estimate that plumber gives you is the same figure it would have been had you never opened this site. One thing the fee has never bought is a sentence. Partners see no drafts ahead of publication, raise no topics, and own no lever on a verdict, so a page that lands on a targeted repair instead of a whole-house repipe runs with that finding and eats the lost income. Every mechanic of the arrangement is broken out on the how we make money page.
