Editorial policy
How we research and review this site
Every page here is meant to help someone with a water heater problem make a safe, informed decision. This page explains how the information is gathered, checked and kept current.
Sources
Where the information comes from
Statements about safety, codes, efficiency and law are taken from primary sources and linked on the page where they are used: the U.S. Department of Energy, the U.S. Environmental Protection Agency, California statutes, the Contractors State License Board, the Los Angeles Department of Building and Safety, Los Angeles City Planning, the Los Angeles Housing Department, CAL FIRE, LADWP and the regional gas utility.
Each cited statement carries a numbered marker that jumps to the source list at the bottom of the page, so readers, and the search and AI systems that summarize pages, can check exactly where a fact came from.

Review
Review dates and corrections
Every guide and service page shows the date it was last reviewed. Pages are checked again when a cited rule, standard or program changes, and outdated statements are corrected rather than left in place.
If you spot something inaccurate, use the contact page and describe what is wrong and where. Corrections that change the meaning of advice are noted on the page.
Who runs this site
Independence and the referral model
This site is operated as a referral service. That arrangement does not influence what the guides recommend: they tell you when a repair is likely unnecessary as readily as when it is needed.
