    Turn off the electricity to the well and turn on your water faucets. Wait for no water to come through before beginning installation.

    Once unscrewed, remove the tank.

    Put the new tank in the old tank's place. Wrap pipe thread tape on the threads of the pipe and screw it into the pressure tank.

    Turn back on the electricity and test for leaks.
