Editorial Standards

Three things live on this page: where the price ranges in the calculator and guides come from, why some pages carry plumber quote links, and what happens when a reader tells us a number is off.

Where the numbers come from

The ranges you see, from a straight tank swap to a full tankless conversion, are built from plumbing-trade pricing surveys, manufacturer list pricing, and published labor-rate data, not from a single contractor's rate card or anything a partner asked us to publish. Unit type, tank size, fuel, and installation complexity each move the estimate on their own, and the guides explain why in the same place the number appears. No plumbing company, manufacturer, or supply house pays to have its pricing shown more favorably here, and none is named as the recommended brand.

The quote links, and how they pay for this site

Several pages connect readers to a network of local plumbers, and this site earns a referral fee when one of those connections turns into hired work. That fee comes from the referral network's marketing budget, not from your invoice, and it plays no role in which plumber gets matched to your ZIP code or what they ultimately quote you. If a page tells you to get a second opinion before signing with anyone, that advice holds even for a plumber who reached you through one of these links.

Keeping the ranges current

Every guide carries an updated date, and that date moves when a number actually changes, not on a fixed schedule to look active. The site's baseline figures get reviewed every few months, or sooner if a reader flags something that looks off.

Who writes here

Jessica Martinez researches and writes the cost guides, the FAQ answers, and the calculator copy on this site. She is not a licensed plumber, and nothing published here substitutes for a licensed professional inspecting your actual water heater and plumbing setup before you commit to a job. I'm Chris Terry; I own this site, set the rules on this page, and handle corrections, but I stay off the byline because I am not the one doing the research or writing. The authors page has more on Jessica's background.

Corrections

Spot a stale figure, a wrong year, or a claim that doesn't match its source? The contact page is the fastest route to us. We trace a flagged number back to where it came from before we touch anything, and when a correction meaningfully changes a cost figure, the page's updated date moves and we note what changed instead of editing it away quietly.
