Most water heaters don’t die all at once — they warn you first. Catch the signs early and you replace it on your schedule instead of mopping up a flooded floor on a Sunday morning. Here are the seven we tell Northwest Florida homeowners to watch for.
1. It’s 10+ years old
A standard tank lasts about 8–12 years. Check the serial number on the label — the first digits are usually the year. Past a decade, you’re on borrowed time.
2. Rusty or discolored hot water
Brown or metallic-tasting hot water often means the tank is corroding from the inside. Once rust starts, a leak isn’t far behind.
3. Not enough hot water
Running cold halfway through a shower usually means sediment has built up and cut your usable capacity.
4. Popping or rumbling noises
That’s hardened sediment on the bottom of the tank. It makes the heater work harder, run hotter, and fail sooner.
5. Water around the base
Even a small puddle or dampness means a slow leak. Tanks rarely reseal themselves — this one’s a replace, not a repair.
6. Higher energy bills
An aging or sediment-filled heater burns more energy to do the same job. A steady climb with no other cause points at the tank.
7. Repeat repairs
New heating element, then a thermostat, then a valve — when the repairs stack up, you’re better off putting that money toward a new unit.
Tank or tankless?
If you’re replacing anyway, it’s worth deciding between a standard tank and a tankless system. We break down the real installed costs for our area in our water heater cost guide.
