Watch for these
Signs your water heater may need replacement
Water heaters often show warning signs before they stop working. A unit nearing the end of its expected service life, water leaking from the tank itself and hot water that runs out faster than before are common indicators.
Temperatures that change without warning, rusty or discolored water, loud popping or rumbling, visible corrosion around the connections, rising utility bills and frequent repairs point the same way, as does a heater that no longer meets the household's demand. A failed thermostat or valve may still be repairable; a leaking or heavily corroded tank usually is not.
