Why LA water heaters die early (and how we size around it)
Here’s the local truth most companies won’t lead with: Southern California’s water is hard, and across much of LA — the San Gabriel Valley especially — it’s very hard. Those dissolved minerals bake into scale on the tank floor, which insulates the burner, makes it work harder, and shortens the heater’s life — which is why so many LA tanks fail at 6–10 years instead of 12+.
When we handle water heater replacement Los Angeles, we size it correctly for your household’s real demand and set it up to survive the hard water (proper anode and a flushing plan or scale protection). Do it right, and the new unit lasts; do it cheap, and you’re back here in a few years. We’ve installed thousands across LA since 1997.
