Water Heater Maintenance — How to Flush Your Water Heater

The experts at Outstanding Plumbing perform routine water heater maintenance and inspection for safety and efficiency. One of the many services included in these maintenance checks is a water heater system flush.

Flushing your water heater clears out the sediment that builds up in your pipes and causes your plumbing to lose efficiency and risk obstruction. It’s a fairly simple procedure, but it’s absolutely critical to the health of your unit. Your water heater should be flushed once a year.

You can flush your water heater on your own! Watch the instructional video or read the transcript below to learn how.

Here are the steps to flush your water heater:

  1. Turn the thermostat to the “vacation” setting.
  2. Shut off the cold water supply valve.
    (NOTE: If you aren’t sure which valve is the cold water supply, look on the top of the water heater. There should be a stamp on the device telling you which is which.)
  3. Connect a garden hose to the drain (shown in video).
  4. Open a hot water faucet in the house — any sink faucet will do.
  5. Place the other end of the hose in a floor drain.
  6. Open the valve and let all the water drain out.
  7. One word of warning: if your water heater is older, the drain valve may be rusty or broken, which will make it difficult to fully seal. Before you perform a water heater flush, make sure that the drain valve can be tightly and properly sealed.
