Signs Your Water Heater Needs Repair

Is your water heater trying to tell you something? Don't ignore these common warning signs:

No hot water or water that isn't getting warm enough
Inconsistent water temperature — hot one minute, cold the next
Rumbling, popping, or banging sounds coming from the tank
Discolored or rusty water coming from your hot water tap
A leaking tank or pooling water around the base of your unit
A noticeable increase in your energy bills without explanation
Your pilot light keeps going out (gas water heaters)
