Tools for electric water heater replacement or new installation
For safety, turn off electric supply from the circuit breaker panel and use a voltage detector to verify if there is still current at the junction box.
Remove the available hot water from the tank by opening the hot water faucet; then you should turn off the cold water supply to the unit.
Drain all the water in the unit by connecting a hose to the water heater valve.
Use the screwdriver and other tools to disconnect the electric wires attached to the water heater (Note that you need to take a picture of the connection). Also, you need to disconnect the hot and cold water supply pipes at the top of the unit. Check the plumbing to know if the unit was plumbed with copper piping and gently cut it out with a tubing cutter.
We recommend that you remove the discharge pipe from the T&P valve.
Remove the old water heater and if possible, use a dolly for this job. Lift and properly place the new tank. Make sure it is well balanced in the drain pan. Check the electrical supply and plumbing pipes to ensure that they can fit into the new unit.
Use the sandpaper cloth to prepare the pipe in case your old water heater used copper wiring.
Carefully connect the electrical wiring by using the previous wire connections as a guide. You should have a label tag or snap a picture before the previous disconnection.
Connect all the wire and double check if everything is correct (using the picture you took previously)
Connect the hot and cold water supply lines and plumb them with copper piping if that was applicable in your old unit
Lastly, attach the discharge pipe to the T&P Valve and tighten it properly, then fill the tank with water and turn on the power.
If you followed all the procedure, your water heater would start working efficiently. If there is an issue, you need to evaluate the procedure or call professionals from Just Water Heaters.
