What we especially want to hear
- A spec that contradicts its source. If a number on a brand datasheet page no longer matches the linked official page, tell us — model lineups change quietly and the capture date makes every row checkable.
- A better source. We prefer official pages, spec sheets and install manuals. If you hold a primary source we've marked "(to be verified)", we'll take it.
- Your utility's hardness figure. The hardness by state reference improves with every official city data point readers send.
Response time
This is a small independent operation — expect a few days, not hours. Genuine corrections jump the queue.
