How to Treat a Smelly Electric Water Heater How to Treat a Smelly Electric Water Heater

An electric water heater is a part of many home heating solutions and systems. It is fairly reliable and lasts on average 8 to 10 years, with proper maintenance. Sometimes a water heater will start to send off smelly gases. These gases can fill up several rooms and even the whole house with time. Here are a few things you can do to treat a smelly electric water heater.

1 - Add Chlorine

You can add chlorine to the hot water heater system. To do this you will need to turn off the electricity and the water to your home. You will then need to drain off some of the excess water in the hot water heater (about 10 gallons). Once you've done that, you can pour a couple of gallons of chlorine (using pool chlorine is just fine) into your hot water heater. Before you use the hot water, you will need to drain the chlorine solution and allow it to fill up with clean water again.

2 - Replace Anode

Most hot water heaters come with a magnesium anode. These anodes sometimes are responsible for the smelly sulfur odors that are produced. You can replace this anode with an anode made of aluminum or zinc.
