After a period of time, the water heater will accumulate bacteria, become dirty and black, and there will be a lot of scale inside the water heater. If not cleaned in time, many pollutants will be preserved, posing great harm to human health.

Step 1: Unscrew the hot water outlet nut, block the hot water outlet, and prevent the water from flowing out of the water heater. Unscrew the cold water outlet nut together, connect the hose (showerhead pipe is sufficient) to drain the water until there is no water flowing out of the cold water outlet. For a 50L water heater, drain for about 1 hour.

Step 2: Remove the hose connected to the cold water outlet, connect one end of the hose to the hot water outlet and the other end to the faucet. Turn on the faucet and fill it with water for 1 minute, then plug the cold water outlet and let the cold water stay in the inner container for an additional moment. Then turn on the cold water outlet to drain the water, repeating this process several times until the discharged water is clean and stops.

Step 3: After the water flows out, seal it off. When cleaning, it is important to note that the water temperature of the water heater should be below 50 ℃ before cleaning. This water temperature can be directly discharged into the drainage pipeline without affecting the pipeline. When cleaning, if there is a sewage outlet on the water heater, it can be opened together because the direction of the sewage outlet is lower than that of the cold water outlet, and the drainage is more thorough.

Reminder: The inner liner of the water heater should be updated on time every year to prevent serious health consequences.
