Things you need
Gather all the following tools.
 Screwdriver
 Wrench
 Pipe cutter
 Dielectric connectors
 Voltage testers
 Flexible hoses
 Sandpaper
The Process
Remove the water heater from the power supply.
Ensure your safety first. Check there is no electric current supply to the old
heater before touching any wire. The first step is crucial to avoid any harm or
injury.
Drain the hot water.
The step acts as a safety precaution. Empty all the hot water from the faucet.
The water must continue to drain until it becomes cold. Shut down the water
supply to the tank once you feel the cold water. After that, empty the tank.
Connect a hosepipe to the draining valve and direct the water to an outside tub
for safety. In addition, open the hot water valve to speed up tank emptying. 
Disconnect the old water heater's wiring.
It allows you to safely remove the old heater and check any wires that need
replacement. When removing a water heater, shut down the gas supply. Turn
off any gasoline oil that is coming from the tank as well. Always switch off all-
natural gas and propane line connections before removing a water heater.
Disconnect the pipe system entirely.
If any of the pipes utilized are copper, they may need to be cut off. On the
other hand, other materials are easier to disconnect from the tank. Remove the
pipes linked to the tank using a wrench and inspect for any that need to be
replaced. Reuse the pipes if they are good enough to install a new water heater.
New hot water tank installation.
Make any necessary repairs to the room before installing the new tank. Check
to see if the wiring and pipes on the new tank match the wiring and pipes on
the old tank.  Expert  plumbers  in  San Jose make it  easy for  you.  Getting
professional help saves you from stress while keeping you safe.
Sand Copper pipes.
Remember  what  kind  of  plumbing  the  old  water  heater  had  and  prepare
accordingly. Before utilizing any copper pipes on the new tank, sand the pipes.
New water heater wiring.
Remove the junction box casing to gain access to the wire. Now attach the
ground wire to a green screw ground on the heater. Remove white and black
colored wire. Then, take a screwdriver and remove a knockout on the top part
of the tank.
Reattach the pipes.
Reattach all the cold and hot water pipes. Check for leaks by turning on the
water.
Place temperature and pressure discharge valve. 
Install a discharge pipe on the new water heater, ensuring it does not extend too
far over the floor. Install the valve to relieve the rising pressure inside the new
tank.  Install  a  discharge  pipe  on  the  new  water  heater,  keeping  it  from
extending too far over the floor. After that, replace the valve on the tank and
tighten it with a tool to ensure no leaks. You may screw on an adaptor and
cover the threads with plumbing tape.
