What s going on with a solar water heater overflow leak

Check it well, there are several reasons for solar water leakage, if the overflow pipe is blocked, take out the upper joint, blow it from below with compressed air, it really doesn't work after you turn the faucet boiling water on a small point, slowly add water, when the water is not urgent, it will not overflow from the exhaust port, if the overflow pipe is seriously blocked, it will also cause the water tank to deflat, then you need to replace the main water tank; If the vacuum tube is damaged, you need to replace the vacuum tube, if the silicone ring is not tightly sealed or damaged, as long as the silicone ring is replaced, there is another point that the pressure of the water pipe is too large, resulting in the automatic valve is not tightly closed, which will also lead to water leakage, but only need to install the pressure reducing valve, different problems have different solutions, you have to check well, the right medicine

When the water is full, when it flows out of the return pipe, the cold water pipe is still on the water, and it is like one minute to two minutes, once the water is full, within one or two minutes, the cold water sinks and the hot water floats, so it will flow for a while, and the water is too hot, and the water vapor runs out from the exhaust and overflow port.

1. The water supply valve is not closed tightly or the water supply valve is leaking and needs to be replaced.

2. After being filled with water, if the temperature is high, it may cause hot water to roll or water vapor to flow out of the overflow pipe, which can be solved by hot water for a while.

There's a switch that you turn on inadvertently, usually in the scrubbing room, and you can turn it off.

1. It may be because of the mixing valve, pipeline and safety valve, these fittings are blocked, which will cause a large area of leakage. 2. It is also possible that it has been used for a long time, and there is a rupture, for example, the sealing gasket is aging, and the sealing effect cannot be achieved, and it will also cause water leakage. 3. Another reason is that the inner tank of the water heater, if the seepage zone is ruptured due to the temperature difference, it will also cause the overflow port to slowly seep water.

2. The solution to the leakage of the solar overflow 1. If it is because of the failure of the mixing valve or pipeline, including the accessories such as the safety valve, you can directly replace the relevant accessories to solve the problem. 2. If the problem is caused by the leakage of the water tank, it is more expensive to replace, because the inner tank of a water heater is relatively high, according to the same, it is recommended to change to a new water heater. The best way to avoid this is to protect the liner from corrosion, and to clean and maintain it regularly.

For example, we need to clean the water heater every one or two years to prevent the growth of scale, so as to effectively extend the service life of the water heater. Third, the common fault of solar water heater Some customers report that the solar water heater at home can not produce hot water, perhaps because there is a lot of dust on the surface of the vacuum tube, or there are shelters, resulting in poor thermal efficiency, coupled with insufficient sunlight radiation energy, and the temperature is relatively low, so it will lead to no hot water when you go home at night. The solution is that we need to wipe the dust on the surface clean, and remove the obstruction, and it is necessary to replace the vacuum tube, which can effectively avoid the problem of lack of hot water.

This is a normal phenomenon, when the water in the tank is full of heat, the cold water sinks, and the hot water floats, forming a convection. During convection, the water surface may rise above the upper end of the overflow pipe, and the overflow pipe will drip water. In addition, water droplets formed after condensation of water vapor will also drip out of the overflow pipe, so there is no need to suspect a water heater malfunction.

If the water heater is faulty, the reasons can be:

1: The water level probe is faulty, resulting in inaccurate water level detection.

Solution: Replace the water level probe.

2: The solenoid valve is faulty, resulting in the water being continuously supplied due to the loose closure.

Solution: Replace the solenoid valve.

3: Instrument controller setting problem or failure.

Solution: Re-set the water supply; Replace the solar meter controller.

4: Problems with the layout of the pipes, causing water to flow backwards.

Solution: Rearrange the solar water and water pipes.

When the liquid level reaches the overflow port, if the liquid continues to inject liquid into the container, the injected liquid will be discharged out of the container through the overflow port, the solar water heater in daily life is an example, when the liquid level in the water heater is too high, the container will be discharged through the overflow port.

Encyclopedia overflow.

<> leakage of the overflow port of the solar water heater is most likely caused by the blockage and corrosion of the mixing valve, pipeline, safety valve and other accessories of the water heater. The second is the water leakage caused by the rupture of these accessories, and it may also be the water leakage caused by the aging and cracking of the sealing gasket of the accessories and the gradual deterioration of the sealing effect.

Solution to the leakage of the overflow of the solar water heater:

Generally speaking, in addition to the leakage of the water heater, faults such as mixing valves, pipelines and safety valves can be solved by replacing accessories.

Because the leakage of the body is the cause of the rupture of the inner tank, which can not be used normally, and the replacement of the inner tank of the water heater is also relatively high, in this case, it is necessary to replace a new water heater.

This answer is applicable to most brands of solar water heater models such as Four Seasons Muge, Sun Rain, and Haier.
