1. Turn off the power supply, close the water inlet, open the hot water outlet to release air, and open the safety valve to release water.
2. Hot water outlet is generally lower than safety valve. Under the action of gravity, the safety valve can't get out of the water. You have to blow into the hot water outlet to blow the water out of the hot water pipe. If there is no gravity water in the hot water pipe, the safety valve will come out.
