For many homeowners, replacing an old water heater is simpler than they imagine, especially if the new unit is similar to the old one. If you want to switch from electric to gas or vice versa, however, discuss the various installation options with a professional.

If your home is in an earthquake zone, you will need to install straps around the new water heater (check with your local building department for exact specifications).

If the new tank is a different height than the old one, use flexible pipe connectors for the water inlet and outlet; they will bend as needed to make the hookup.

If the pipes are not threaded, replace them with threaded nipples, and secure the connectors to the nipples with an adjustable wrench. Install a new temperature and pressure-relief valve on the new tank, and test it by squeezing the lever.

1. After draining the tank, unscrew the inlet and outlet fittings.

1) After shutting off the water and gas or power supply to the tank, connect a hose to the drain valve at the bottom of the tank, open the valve, and run it to a nearby drain or to the outdoors. Use two wrenches to unscrew the inlet and outlet fittings from the top of the tank.
