How to Drain a Water Heater

Giriş

To keep your water heater running in tip-top shape, you need to drain it about once a year to prevent excess sediment and mineral deposits from building up and settling in the tank, as well as on the heating elements, which can decrease efficiency.

You can also use this guide if you’re replacing a water heater, which will need to be completely drained before removing the old one.

Locate the drain valve on your water heater, which is placed at the bottom of the tank. Yours may look different than what's pictured, sometimes looking like a traditional garden hose spigot
There may already be a drain hose attached to the drain valve that leads to a nearby drain. If not, you can connect a garden hose to the drain valve and drain the water to a nearby floor drain or sink.
To begin draining your water heater, open up the drain valve by rotating the knob counter-clockwise.
If you're just performing maintenance, simply let the water drain for five minutes or so to flush out any sediment buildup.

Once complete, be sure to close the drain valve all the way and turn the water line back on, as well as the gas/electricity and the water heater itself. If you drained the tank completely, wait until it’s full again before turning the water heater back on.
