Pro tip: my 8 year old water heater gave out on a Sunday morning and the plumber's invoice has me thinking
I'll be honest, I always figured a water heater was one of those things you just don't think about until it fails, and mine failed on a Sunday morning three weeks ago with water pooling near the base in the garage. I called the first plumber who answered around 7am, and he quoted me $1,850 to swap in a new 50 gallon unit, which felt steep but I didn't have much choice with a house full of people needing showers. What got me was when he said the old one was from 2016 and that ten years is actually about average now, not the 15 or 20 I remember my dad getting out of his. I asked him why, and he said the tanks are thinner and the water here in the Phoenix area is hard enough that it eats through the anode rod faster than folks expect. He showed me the old rod and it was pretty much gone, which I never would have thought to check on my own. Now I'm wondering if I should have flushed the tank once a year like the manual said, or if it would not have mattered much either way. Has anyone here actually gotten 15 plus years out of a newer heater, or is 8 to 10 just what we live with now?
