Electric water heater installation has a few basic steps.
First, remove the old system.
Before any disassembly takes place, you need to turn off the main power to the unit. This is done by simply flipping the breaker switch.
The water must be removed from the tank. Hook a water hose to the drain and let the water flow out to your storm water drain.
Electric water heater installation can get messy and you don’t want the water flowing everywhere. Keep in mind that you will want to open the hot water faucet to allow air to escape the system.
Finally, disconnect the piping from the unit. If the system has removable threaded fittings you can unscrew them with a set of pipe wrenches. If they are welded together they can be simply cut off with a hack saw or pipe cutting device.
Once these steps have been followed you can then safely remove and dispose of the old unit. Because of the weight and “awkwardness” of the heater tank, you may want to use a hand truck to move it, or simply walk it out of the way. Next is the actual electric water heater installation.
Installing your new system is not all that easy for a home DIY mechanic. There are many codes that you must follow to do the job safely and lawfully. You will basically install the water lines in the same style as they were before. Using flex pipe while installing will make the job go faster because of their easy bending capabilities.
Once you have the plumbing done you can close the drain and open the cold water line. This will allow the tank to refill. While filling the tank open the hot water faucet again allowing air to escape. Then check your electric water heater installation for leaks.
Finally you will need to wire the heater to your home. This job should be left to a professional electrician or qualified plumber because of code issues unless you are experienced in this type of work.
