Most water heaters don't die dramatically — they give you warnings for months first. Knowing the signs means you replace on your schedule instead of mopping out a garage at midnight. Here's what we tell Clark County homeowners.
Typical lifespan
A conventional tank water heater typically lasts 8–12 years; tankless units, properly maintained, often run 15–20+. Hard use, sediment buildup, and skipped maintenance shorten those numbers. Not sure how old yours is? The serial number on the manufacturer's label encodes the production date — snap a photo and we can decode it for you over the phone.
The 6 warning signs
- Rusty or discolored hot water. Brown or yellow tint on the hot side only usually means the tank is corroding from the inside. Once a tank rusts through, there's no repair — only replacement.
- Rumbling or popping sounds. That's sediment on the tank floor being superheated. It makes the burner work harder, and it's a leading cause of early tank failure.
- Moisture or drips around the base. Small leaks at fittings can be repaired. Weeping from the tank body itself means the shell has failed — replace it before it lets go completely.
- Hot water runs out faster than it used to. Sediment displaces capacity and insulates the water from the burner. A flush sometimes recovers it; on an older tank it's often the beginning of the end.
- Water takes noticeably longer to heat. Failing heating elements or a tired burner assembly — repairable on a younger unit, a replacement signal on an old one.
- Repairs are stacking up. If you're calling for a second or third fix on a unit past its 8th birthday, the math usually favors a new unit — often a tankless upgrade.
One thing you can do today
Find the drain valve at the bottom of your tank and check the floor around it once a month. A dry floor and a quiet tank buy you time; the first drip is your cue to call before it becomes a flood. If your tank sits above living space or finished flooring, take that first drip seriously — the water damage almost always costs more than the water heater.
