The first method involves opening the drain valve, which can be dangerous if you are using hot water. If you see a slow flow of water after a few hours, it may be time to flush the heater. Once the water drains, you can open the cold water inlet to flush the sediment from the tank. This will loosen the sediment and drain out of the water heater. You should wait several hours after the flushing process before using it to avoid burning yourself or damaging your home's plumbing.
