Most homeowners discover the need for a swap after a combination of warning signs stacks up: a sudden loss of hot water, noisy operation, rust‑colored water, or a constantly tripping reset button.

Once you confirm the heater is beyond repair, the replacement process starts with turning off the gas or electricity, draining the tank, and disconnecting the supply lines. Safety is key—always vent the area and wear protective gear because old tanks can hold high pressure. Next, you choose the right size and type: electric vs. gas, tank‑style vs. tankless, and capacity matching your household’s demand. Installing the new unit involves reconnecting the water lines, attaching the vent (for gas models), and hooking up the power source. Finally, you’ll need to test for leaks, set the thermostat, and maybe prime the system.
