Unscrew the hot water inlet nut to block the hot water inlet and prevent water from flowing out of the water heater. At the same time, unscrew the nut on the cold water outlet, connect a hose (a shower pipe will do) and drain the water until no water flows out of the cold water outlet. For a 50L water heater, draining takes about 1 hour. Next, 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, open the faucet to fill with water for 1 minute, and block the cold water outlet. Let the cold water stay in the inner tank for a while, then open the cold water outlet to drain, and repeat several times until the discharged water is clean.

Finally, tighten the nuts on the cold water inlet and hot water inlet, open the triangle valve, and turn on the hot water from the water heater faucet. After the water flows out, close it. Cleaning precautions: Before cleaning, the water temperature of the water heater should be below 50℃. At this water temperature, it can be discharged directly into the sewer pipe without affecting the pipe. When cleaning, if the water heater has a drain outlet, it can be opened at the same time, because the drain outlet is located lower than the cold water outlet and the sewage can be discharged more thoroughly.
