(1) Because the tap water pressure is too high, water will splash out during the filling process, causing the water in the water tank to flow out of the vent before it is not full. Solution: Adjust the tap water pressure to standard water pressure. (2) The return pipe is too long or is not smooth, causing water to flow from the return pipe in time when the water is full and water continues to be supplied. , it will flow through other vents. Solution: This problem is a natural law and cannot be eliminated by using the return pipe. Installing instruments can solve the problem. (3) The water supply valve or solenoid valve is not closed tightly, resulting in slow water supply. When the water is full, it will flow out of the exhaust hole. Solution: Turn off the water supply valve or repair faulty parts. (4) Water vapor generated when the temperaturere water is too high. This situation is normal.

We can only say that it is possible that the valve on the water inlet pipe of the solar water heater tap is not closed tightly, causing the water to flow back.
When the solar water heater does not leak at all, it indicates that there is not enough water. Either the water has been used, it has flowed back, or there is a malfunction in the water level sensor. the water heater.
You can try adding water to the water heater first. If it starts to overflow as soon as you start adding water, the water level sensor is abnormal.
If there is indeed a lack of water, this means that the water is flowing backwards. The manual valve in the water supply line needs to be replaced.
