Recognize the change
Know the warning signs before your water heater fails
Water that stays cooler than usual, rusty-looking hot water, popping or rumbling sounds and moisture around the tank deserve attention. Fluctuating temperature, a reduced supply and an unexplained change in utility use are also worth reporting.
Describe when the symptom occurs and whether it has become more frequent. Tell the team if earlier service changed the behavior. Those details help the technician understand the problem without treating a single symptom as proof that the entire unit needs replacing.
