5 Signs Your Water Heater Is About to Fail

Your water heater usually gives little warning before it fails. But certain symptoms show up repeatedly—often weeks or months ahead of a breakdown. Here are five signs that your water heater may be about to fail and what to do next.

1) Hot water runs out faster than usual
If you’re finding that showers feel shorter, dishes don’t rinse as well, or the tank seems to “empty” sooner, the heating capacity may be declining. Over time, sediment buildup can reduce heat transfer, causing the unit to struggle to reach and maintain temperature.
