1. During the use of the water heater, condensation, dripping, corrosion and yellowing occurred at the buckle seam of the right end cover. Open the right end cover for inspection. If there is a lot of condensed water, dripping water at the port, yellowing of the port, water leakage, deformation of the heating pipe, etc. , indicating that the port seal is not tight and there is water leakage, so the heating pipe should be disassembled for inspection and maintenance.

Second, in fact, it is too troublesome to disassemble and repair welding, and the repair cost is relatively expensive. It is a pity to replace it with a new one. We can buy a cold water valve that matches the water inlet pipe connector of the electric water heater in the water heating accessories store. Turn off the main tap water valve, unscrew the hose connector, put on a new valve, and check whether the connector is watertight.

Thirdly, when we heat the water heater, we should close the newly replaced valve. Please rest assured that the water heater tank is full of water at this time, and the water heater will never dry. Open the valve every time the water heater is used, and close the valve when the water heater is not used at ordinary times. Ensure that the water pressure on the wall of the water heater box is at the bottom. This is safe.

Generally speaking, if the liner leaks, it is not recommended to repair it, because the enamel of the liner has been damaged, and it will leak if it is repaired for a long time. From the point of view of dripping, such as leakage of sealing ring or flange, it may be solved by replacing sealing ring.

You can contact the manufacturer to see if your liner has passed the warranty period. During the warranty period, most manufacturers will change their machines. If the warranty expires, you have to buy it again. Of course, this problem must be repaired. Please ask the manufacturer to send professional maintenance personnel to have a look.

First, we know that water leakage of water heaters is dangerous, fittings are blocked and corroded, fittings are damaged, and fittings gaskets are aged and damaged. It is suggested to investigate from these three aspects, or find a professional maintenance master to check and repair; At the same time, pay attention to regular maintenance when using water heaters.

Second, if the gas water heater leaks, it is not a big problem, but it should be repaired to avoid leakage, especially at the interface apron. If the gas water heater leaks inside, don't use it again. Taking time to deal with it will damage the internal fittings. There is no harm. They are completely different systems, and this problem has been taken into account in the design.
