Signs Your Water Heater Needs Repair
By HomeAssist Connect Editorial Team ·
Short answer: The most common signs are hot water that runs out quickly, rumbling or popping sounds, rust-colored hot water, moisture around the base and a unit that's more than about 10 years old.
Warning signs
- Hot water runs out faster than it used to.
- Rumbling or popping — sediment buildup in the tank.
- Rusty or metallic-smelling hot water.
- Water pooling around the base or in the drain pan.
- A pilot light that won't stay lit (gas units).
Repair or replace?
Parts like thermostats, heating elements, thermocouples and valves can often be replaced. A leaking tank itself usually can't be repaired. Age matters too: a tank water heater nearing 10–12 years is often a replacement candidate.
Houston-specific tip
If your water heater is in the attic, check that the drain pan and its line are clear. Attic leaks can damage ceilings quickly.
