Watch for changes
Common signs your water heater needs attention
Many problems develop gradually: inconsistent temperatures, hot water that runs out quickly, low hot-water pressure or higher utility bills. Rust-colored hot water and rumbling, popping or banging sounds are also worth reporting.
Water collecting around the base of the tank, or pilot light and ignition problems on a gas unit, should be checked before they lead to water damage or a complete breakdown. The technician inspects the system and identifies the cause before recommending work.
