Hot Water TankSpend some time this summer thinking about your hot water tank. It might be chugging along just fine, but if it ever stops you’ll be sure to notice the difference. That’s why you should drain your hot water tank; it’s a great way to extend its life.

First make sure to turn off the water feed to your tank. The location and procedure to do this will depend on your exact water tank make. Next, turn the dial to pilot. Then, connect a hose to the valve at the bottom of the unit. Make sure the draining end flows into a floor drain or outside, a driveway is ideal.

Before turning the drain valve a word of warning, the water can be very hot so make sure to take the necessary precautions to avoid hurting yourself. Once you’ve double-checked everything, turn the drain valve open. Wait until the flow of water has stopped. After that, turn off the drain valve and disconnect the hose. There is a chance some water will be left in the hose so take care.

Turn the supply of water back on. It’ll take some time for the tank to fill up so don’t expect a steady supply of water immediately. Finally, turn the dial from pilot back to its original setting.

    • You are correct about the title, very observant. Removing sediment from the inside of the tank allows the burner to heat the water more efficiently, which shortens the run time.

  • Be very careful when you drain the tank! The water in your water heater is extremely hot. It’s a good idea to give the water some time to cool before you drain it from the tank, to prevent injury.
