Tools and Materials Needed 

  • New hot water heater
  • Pipe wrench or adjustable wrench
  • Pipe cutter or hacksaw
  • Pipe joint compound or plumber’s tape
  • Copper pipes and fittings
  • Flex connectors and shut-off valves
  • Gas pipe fittings and gas detector (for gas heaters)
  • Teflon tape
  • Wire connectors
  • Electrical tools 
  • Pliers

1. Turn Off Utilities

For the sake of safety, turn off the utilities. You will need to turn off the power at the main circuit breaker for electric heaters. If you’re working with a gas heater, turn off the gas supply at the valve. 

2. Drain Old Water Heater

Now, you must drain any remaining water from the old heater. Connect your garden hose to the drain valve and place the other end into a floor drain or outdoors. Allow the water to drain completely from the tank. 

3. Disconnect Old Water Heater

With the water completely drained, you can now disconnect the tank’s hot and cold water supply lines located on the top of the water heater. You will also need to disconnect the gas lines or electrical wiring, depending on the tank type. If there are any other fittings or parts attached to the water heater, you will want to remove them as well. 

4. Prepare the Installation Area

Remove the old water heater out of the way (you may need additional help with this). Clean the area of any debris and objects, ensuring a clean and dry work area. Check the floor to ensure it is leveled and supports the new water heater. 

5. Position the New Water Heater

With the old water heater out of the way, you can now place the new one in position. Connect the cold and hot water supply lines to the heater using the appropriate fittings. This is also the time to install any necessary shut-off valves. 

6. Connect the Gas Line or Electrical Wiring 

Connect the power supply lines depending on the type of water tank you’re working with. The instructions for connecting gas or electrical tanks vary, depending on their manufacturer. Follow the instruction manual carefully to ensure a safe installation. 

7. Fill and Test the Water 

With the tank connected, you can begin filling it with water. Locate and open the water supply valve, allowing the tank to fill to the appropriate level. Ensure you also open a hot water faucet during this step, which will help release air from the system. As the water fills, look around the tank for any leaks. 


Then, turn on the power at the electrical panel (for electric heaters) or follow the instructions to light the pilot light or burner (for gas heaters). 

8. Adjust the Temperature Settings

Finally, locate the thermostat and set the temperature to your desired levels. Allow the water at least an hour to heat up before testing the temperatures and adjust as needed.
