1. Use leakage protector: If you have a leakage protector at home, you can use it to test whether the water heater leaks electricity. Insert the protector into the power socket of the water heater and turn on the switch of the water heater. If the protector trips, it means there is a leakage problem in the water heater.
2. Use a digital pen: A digital pen allows you to read the voltage on the water heater. Plug the red tip of the stylus into an electric socket of the water heater, and then ground its black tip. As shown in the figure, the digital stylus will display the voltage of the water heater. If the reading is normal, it means that the water heater is not leaking. On the contrary, it is necessary to further check the inside of the water heater.
3. Check the appearance of the water heater: If there is friction and impact on the surface of the water heater, the internal circuit of the water heater may be broken, resulting in a leakage accident. Checking the surface for scratches, damage and abnormal deformation can help you confirm whether there is a potential risk of electric leakage in the water heater.
4. Clean the water heater regularly: after the water heater is used for a period of time, there may be problems such as looseness and poor contact, which may lead to wire burning and lead to leakage. Therefore, it is very important to clean the water heater regularly. Check the wires of the water heater once a month for damage, looseness and aging, and replace or repair them in time when problems are found.
In short, in order to ensure family safety, we should attach great importance to the leakage of water heaters, check water heaters regularly, and take necessary protective measures to ensure the safety of household electricity use. If you find water leakage in the water heater, you'd better seek the help of professional technicians, and don't carry out self-maintenance or testing.
