The main warning signs of a failing water heater are rusty hot water, rumbling or popping sounds, water around the base, and hot water that runs out faster than it used to. Age matters too, since older tanks are more likely to fail.
Rusty or Cloudy Hot Water
If only the hot water looks brown or rusty, the inside of the tank may be corroding. Cloudy water or small bits in the water can come from sediment breaking loose. Both are signs the tank is wearing out.
Noises From the Tank
Minerals in the water settle at the bottom of the tank over time. When the burner or element heats that layer, it can pop, crackle, or rumble. Heavy sediment makes the heater work harder and can shorten its life.
Less Hot Water Than Before
If showers turn cold sooner than they used to, sediment may be taking up space in the tank. A broken dip tube, which sends cold water to the bottom of the tank, can also cause this. Water that swings between hot and lukewarm may point to a thermostat or heating problem.
Moisture, Leaks, and Age
Water around the base, drips from fittings, or rust on the outside of the tank are serious signs. A tank that leaks from its body usually cannot be repaired. Check the label on the heater for its age. If it is getting older and showing other signs, it may be near the end of its life.
If you notice these signs, have the heater checked before it fails completely. A failing tank can leak suddenly and flood the area around it. A plumber can check the heater and tell you if a repair or a replacement makes more sense.
If your water heater is showing signs of trouble, call JPR Plumbing at (833) 603-1840. Flushing the tank and testing the relief valve during routine maintenance visits can help it last longer.
