Why do they say you need to drain your water heater every year?

Danny Lipford: Susan asks, “Why do you say you have to drain your water heater every year?”

The reason it is important to drain some water from your water heater at least once a year is because it moves much of the debris that settles to the bottom of the tank outward. Now you don’t have to drain all of the water, but you do need to drain a few liters at least once a year.

Well the sediment, if you leave it there, will really reduce the life expectancy of your water heater because it just has to work a lot harder. This also costs you more money in terms of energy costs.

And it’s so easy to drain some of the water. All you have to do is connect your garden hose directly to that drain valve, turn the drain valve on, and when you’re on the other end of the hose you’ll see what I mean when a white, milky sediment comes out of the other end . You need to open the pressure relief valve to allow the water to drain.

Well, these tasks don’t cost you any money at all, but they will save you some.
