Water heater components to be aware of
To perform routine water heater maintenance, you’ll need to know your water heater even better. Before you begin any maintenance, you should know the following points.
Water shutdown valve: In the event of an emergency, this is where you will turn off the flow of water into your water heater. If it’s a dial, you can stop the water flow by turning it clockwise (righty-tighty). To halt the flow, turn the lever until it is perpendicular to the pipe.
The gas shutoff valve: like the water shutdown valve, is vital in an emergency. It’s a lever generally found around the bottom of the water heater.
Heating element: The heating element of your water heater is housed inside the device, but depending on the type of water heater, you may be able to access it from the outside. If you have a gas water heater, it functions similarly to a stove burner at the bottom. The water is commonly heated by two horizontal electric rods in an electric water heater.
An anode rod is a metal rod hanging down into the water from the top of your water heater tank. Its role is to attract any corrosive minerals that may be present in your water so that they erode the rod rather than the tank’s interior. Anode rods degrade and must be replaced regularly.
