Before replacing it, turn off the power to your current water heater. For gas models, shut off the gas valve and extinguish the pilot light. For electric models, switch off the circuit breaker. Next, shut off the water supply to the heater and drain the tank by connecting a hose to the drain valve. Open a hot water faucet elsewhere in the house to allow air into the system.

Disconnect the water heater. For gas models, detach the gas line and venting system. For electric models, disconnect the electrical wiring. Also, disconnect the water inlet and outlet connections. Carefully remove the old water heater with a dolly or assistance, following any local regulations for disposal.

Install the new water heater by positioning it in place and reconnecting the water, gas, or electrical lines following the manufacturer’s instructions. Make sure to check for leaks. Once everything is connected, slowly turn the water supply back on, check for leaks, and then restore the power. For gas models, relight the pilot light according to the instructions. Finally, set the thermostat to your desired temperature for an easy replacement.
