How Often Should I get My Water Heater Flushed? It is recommended that you flush your water heater at least once per year. Doing so will help to prevent the potential problems that sediment can bring over time.
If not regularly flushed, your water heater can corrode more quickly. The sediment can also block or clog the pressure and relief valve (which helps keep your water heater from exploding).
To flush your hot water tank, simply turn on the cold water spigot leading into your hot water tank. Let it run for a few minutes until the water exiting your hose runs clear. This may take a bit. While the water might be running clear and isn't brown, you may still have some sediment.
