Tips to install a new water heater
Turn off all electric, gas and water operating switches and valves before installing a new water heater. It is crucial to turn off any electrical circuits at the breaker box panel and place a piece of masking tape over the switch, so that no one turns it on during installation process. Make sure the place where the water heater is to be installed has enough space for 2 feet around and 30 inches above the water heater. The installation area should be clean and dry. Line up all your plumbing connections and make sure that the unit is straight, by using a torpedo level. After setting the tank in place, install the pressure relief valve and connect the water lines using Teflon tape on copper connections and joint compound on any galvanized ones. Fill your tank with water. Turn on all the electric circuits and put on the electric switch of the heater.
