How Long Do Water Heaters Last in Central Texas? (Less Than You'd Hope)

Ask the internet and you'll hear water heaters last 8-12 years. That's a national average — and the nation doesn't have our water. Central Texas runs 8-15+ grains of hardness, and every grain settles out as scale on the bottom of your tank, where it shortens the unit's life from both directions: overheating the steel and corroding it.

Unflushed tank on hard water: 6-10 years. The same tank flushed annually: 8-12. Add a water softener and tanks regularly see 12-15. Tankless units run 15-20+ years here, but only with the annual descale flush the manufacturer requires — skip it and heat exchangers scale up well before year ten.

The anode rod matters just as much and nobody checks it: a sacrificial metal rod that corrodes so the tank doesn't. It's spent in 3-5 years in our water; replacing it twice over a tank's life is the cheapest lifespan upgrade in plumbing.

Water heaters rarely fail politely — they fail as a leak, often a big one, usually in an attic or closet above things you like. Past year ten on an unflushed tank, you're not saving money by waiting; you're financing a future drywall repair. Signs the end is near: rust-tinted hot water, popping sounds, moisture at the base, and lukewarm showers that used to be hot.

We flush, inspect, and give you a straight years-left estimate as part of our maintenance plan — and when it is time, most replacements happen the same day. (254) 366-8281.
