Step 1: Disconnect from Electricity
Turn OFF the electricity to your water heater at the circuit breaker panel.
Step 2: Drain the Tank
Open a hot water faucet and allow it to run until the water is cold.
Shut off the cold water supply to the water heater located at the top of the unit.
Connect a hose to the water heater’s drain valve. Open the valve and drain the tank outside, to a floor drain, or into buckets.
Step 3: Disconnect the Electrical
Disconnect the electrical wires on the top of the water heater.
Step 4: Disconnect the Plumbing
Disconnect the hot and cold water supply pipes.
If your water heater was plumbed with copper piping, you may need to cut the pipes.
If you need to cut the pipes, use a tubing (pipe) cutter and leave as much of the pipe as possible.
You may also choose to remove the discharge pipe from the T&P Valve.
Unless the pipe is damaged, you should be able to reuse it on your new water heater.
Step 5: Remove the Old Water Heater
Once the tank is empty, remove the old water heater.
Step 6: Prepare the Plumbing lines
If your old water heater used copper piping and it was necessary to cut the pipes, you will need to prepare the pipes using sandpaper cloth.
Step 7: Connect the Electrical Wiring
Remove the junction box cover to access the electrical wires.
Attach the ground wire to the green ground screw.
Connect the wires together by twisting them with wire connectors.
Step 8: Attach the Supply Lines and Turn ON the Water
Connect the hot and cold water supply lines.
Step 9: Attach the Temperature & Pressure Discharge Pipe
Install the discharge pipe to the T&P Valve.
Step 10: Turn on the Power and Bleed Hot Water Lines
After your water heater tank has filled with water, turn on the circuit breaker at the main power box.
