There are many situations involving water heaters that can be done by a homeowner. But there are many more that require the experience of a plumber and sometimes an electrician. Only work on water heaters if you're handy and comfortable that you know what you're about to do.
Before doing plumbing work you must perform these safety steps:
Turn the electricity off if you have an electric water heater or turn the gas control knob to PILOT if you have a gas water heater.
Find the cold water line on top of the water heater and turn the gate valve off. The cold line is always located on the right hand side as you face the water heater.
Open a hot tap inside the house at any sink. This relieves pressure on the lines.
Twist the knob on the drain valve to open it on the water heater. It's located at the bottom of the water heater and looks like a hose bib. Drain out a gallon of water from the water heater, so it's not completely full at the plumbing connections on top.
Tell everyone in the house or building to use cold water only.
Whenever removing electric elements on an electric water heater, be sure that the electricity is turned off.
Whenever replacing the drain valve on a gas or electric water heater, be sure to turn the gas control knob to PILOT or to turn the electricity off.
