How to Know Your Water Heater Is About to Fail (Before It Bursts!)

Most homeowners don’t think about their water heater until the shower runs cold — or worse, the tank leaks all over the floor. Here are the top warning signs your water heater is failing and what to do before it becomes an expensive emergency.

1. Water temperature keeps changing

If water is hot one minute and warm the next, your heating element may be wearing out. This is one of the first signs the heater is aging.

2. Rust-colored water

Brown or yellow water means rust inside the tank — and when rust starts, leaks are not far behind.

3. The tank is making popping or rumbling sounds

Mineral buildup causes pressure inside the tank. If ignored, it can crack and leak suddenly.

4. Water around the base of the heater

Even a few drops matter. Tiny leaks grow fast and can flood your home.

5. Your heater is 8–12 years old

This is the normal lifespan. If your unit is older, consider replacing it before you face emergency repairs.

➡ If you notice one or more of these signs, call a professional water heater technician in Dallas ASAP. Same-day inspections help avoid leaks, damage, and expensive replacements.
