Can the overflow pipe of the solar water heater be blocked?

The overflow pipe of a solar water heater is used to show that the water is full. When plugged, air enters the tank and runs through the hole of the thermostat. It's useless but it's okay.

yes, that's it. When the water supply is full, the water leaks out from the overflow pipe, and it is correct that the water supply valve will not leak after the water supply valve is closed.

Can't be plugged. The overflow pipe is a safety setting to prevent excessive water pressure from damaging the water heater. You can consider setting up a water level valve, and the water will be automatically turned off when the water level is reached.

This can't be blocked, maybe your solar energy is too full of water and causes overflow, it is estimated that it is a problem with the water limit valve!

If it is with a controller, it may be that the temperature probe is bad, and if it is a float on the water, it should be that the float is bad and cannot be turned off. Another possibility is that cold water is strung up through the hot water pipe, and the solution is to turn off the valve of the hot water pipe when the hot water is not in use.

Can't be blocked, that's for sure. It could be that your water level control valve is broken, or it could be that the overflow pipe is clogged.

Can't be plugged. This is also the case in my sister's house. It would have been nice to change it later.

There is no need to go to the picture, in a word: it can't be blocked! Plugging it will endanger your water heater equipment!

The main function of the overflow pipe is to drain water, when the water level in the solar water heater reaches the highest, if the water consumption is not large, the water temperature in the water tank will not only increase in continuous sunny days, but also overflow a little water due to the principle of thermal expansion. There is also a situation when the solenoid valve is broken and the water is constantly being fed, the water will flow out of the overflow pipe.

It can be plugged up, and the water heater is energy efficient.

It can't be blocked, it's the float valve that is broken

It is an overflow valve, and it will flow out when it is full.

This really can't be blocked.

It will automatically stop the water supply.

There are two possible things that could go wrong

1) The temperature probe is bad.

2) The float is bad.

Reason: (1) If the solar energy is equipped with a controller, it is a problem with the temperature sensing probe.

2) If the solar energy is brought to the water with a float, the float should be bad and not dead.

How it works. Sunlight shines through the first layer of glass of the heat absorbing tube to the black heat absorbing layer of the second layer of glass, absorbing the heat of sunlight energy, because the two layers of glass are vacuum insulation, the heat transfer will be greatly reduced (radiation heat transfer still exists, but there is no heat conduction and heat convection), most of the heat can only be transferred to the water in the glass tube, so that the water in the glass tube is heated.

The heated water becomes lighter and enters the thermal insulation storage bucket along the heating surface of the glass tube, and the water with relatively low temperature in the barrel enters the glass tube along the backlit surface of the glass tube to replenish, so that the water in the thermal insulation storage bucket is continuously heated, so as to achieve the purpose of hot water.

Answer: If the solar energy is with a controller, it may be that the temperature probe is broken, if the solar energy is with a float on the water, it should be that the float is broken, and it is not dead Note: When it is found that the cold water is strung up through the hot water pipe, the solution is to turn off the valve of the hot water pipe when the hot water is not used.

What is the reason why the overflow pipe of the solar water heater keeps flowing water?

If the solar energy is with a controller, it may be that the temperature probe is broken, if the solar energy is with a float on the water, it should be that the float is broken, and it is not dead Note: When it is found that the cold water is strung up through the hot water pipe, the solution is to turn off the valve of the hot water pipe when the hot water is not used.

There is also a possibility that the float is broken.

If the solar energy is equipped with a controller, it may be that the temperature probe is broken, and if the solar energy is brought to the water with a float, the float should be broken and cannot be turned off. When it is found that cold water is flowing up through the hot water pipe, the solution is to turn off the valve of the hot water pipe when the hot water is not in use.

The solar water heater first feeds the cold water into the hot water storage tank, and then transports the heat through the collector to the insulated water tank. The hot water storage tank is connected to the indoor cold and hot water pipelines, so that the whole system forms a closed loop.

Routine maintenance. 1. When installing a solar water heater, there may be dust or oil smell in the water pipe, and you can open the faucet to remove debris when you use it for the first time.

2. The water stored in the solar water heater should be discharged regularly according to the local water quality conditions, and the drainage time can be selected in the morning when the collector is at a lower temperature.

3. The surface of the solar water heater should be wiped regularly according to the amount of dust falling in the area, and it can be cleaned by itself when it rains, and the surface of the water heater can be kept clean to obtain a higher heat collection efficiency.

4. When you don't use hot water for many days on sunny days, the hot water temperature is very high, please turn on cold water first, and then hot water when using the solar water heater to avoid scalding.

5. There is a filter screen device at the outlet of the faucet, and the scale and debris in the water pipe will gather in this net, which should be removed and cleaned regularly, so as to increase the smooth flow of water.

6. In winter, it is very common for the pipeline to be frozen, such as finding that the pipeline has been frozen but the pipeline has not yet cracked, and it can be automatically dredged after the temperature rises. You can also use a hair dryer to blow it, or wrap the water pipe with a towel, and then pour it slowly with warm water, and do not use fire to bake, knock on the pipe or use boiling water to scald, which will burst the pipe. Repeated freeze plugging can easily cause the pipeline to freeze and crack, so it is necessary to strengthen the pipeline insulation measures.

7. Solar water heaters need to be cleaned, inspected and disinfected every two to three years on average, and users can also do some disinfection work by themselves, such as buying some chlorine-containing disinfectants and pouring them into the water inlet, allowing them to soak for a period of time, and then release them, which can have a certain disinfection and sterilization effect.

8. The inside of the vacuum tube needs to be cleaned in two to three years on average in the solar water heater to prevent the scale inside the vacuum tube from affecting the heat absorption effect.

9. If the solar water heater is equipped with a special instrument, pay attention to lightning protection and electricity protection, and do not take a bath and unplug the electric heating plug when thundering.

1. Leakage caused by obstruction and corrosion of mixing valves, pipelines, safety valves and other accessories of water heaters.

2. Water leakage caused by the rupture of the mixing valve, pipeline, safety valve and other accessories of the water heater.

3. The sealing gasket of the mixing valve, pipeline, safety valve and other accessories of the water heater is aging and cracked, and the water leakage is caused by the failure to achieve the sealing effect.

4. Water leakage caused by rupture of the inner tank of the water heater. The best way to avoid this is to protect the liner from corrosion, and to clean and maintain it regularly. For example, if you need to clean the water heater every one or two years to prevent the breeding of scale, you can effectively extend the service life of the water heater.

Precautions for the use of solar water heaters.

If an auxiliary heat source is installed, the auxiliary heat source device and heat exchanger should be checked regularly to see if they are working properly. For the auxiliary heat source is heated by an electric heating pipe, it is necessary to ensure that the leakage protection device works reliably before use, otherwise it cannot be used. Special attention should be paid to water supply when using auxiliary electric heating, and the water volume in the water tank should not be less than 50% to prevent dry boiling without water.

When taking a bath, special attention should be paid to unplugging the power plug, and it is strictly forbidden to use it with electricity.

Clean the liner regularly, after long-term use due to the long-term precipitation of trace impurities and minerals contained in the water, if not cleaned regularly, it will affect the quality and service life of the effluent.

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, which will also cause water leakage.

3. Another reason is that the inner tank of the water heater, if it is ruptured because of the temperature difference, it will also cause the overflow port to slowly seep water, if it is because of the failure of the mixing valve or pipeline, including the safety valve and other accessories, you can directly replace the relevant accessories to solve the problem.

Precautions for the use of solar water heaters.

The stored water in the solar water heater needs to be discharged regularly to avoid pollution caused by long-term water accumulation. The discharge cycle is determined by the local water quality conditions, and the discharge can be done in the morning when the collector temperature is lower.

Turn on cold water and then hot water: If it is sunny for many days and no hot water is used, the water temperature will be relatively high, so you need to turn on cold water and then hot water to avoid scalding.

There are many reasons for this situation: 1: the water level sensing probe is malfunctioning, 2: whether a new water heater has been installed recently, etc., has caused the pipe to be scanned, etc. 3: This is set in the meter.

Recommended" "Dr. Sun" solar, three-bin model (no need for water level sensing probe and solenoid valve), heating and hot water utilization rate in rainy weather are fast, and the after-sales rate is also greatly reduced, which saves time and electricity.

The water supply valve is broken, 100% yes.

When the water is full, just stop the water.

The steam came out of the water heater.

What should I do if the water heater does not have water on it, and it runs as soon as it is on the underwater water pipe.

Summary. Hello dear, <>

The solar overflow pipe is full of water and does not flow the water solar overflow pipe to flow down, one is to flow for a period of time and not flow, generally this is summer, the sun is particularly good, so that when the water temperature in the water storage cylinder is high, the water flows out due to the heat rise and cold contraction. The second is that the water supply valve is not closed tightly, resulting in continuous running water. My solar water heater had such a failure, and the valve was replaced without leakage.

The overflow pipe is full of water on the solar energy and does not run water.

Hello dear, <>

1. The water in the water tank has been emptied, and it can be used after it is full of water and heated. 2. The pipeline interface falls off or is blocked, and the pipeline is reconnected or dredged. 3. In winter, the upper and lower water pipes may freeze.

The sun melts on its own about 3 hours after it comes out. In cold areas, a vent valve can also be installed. 4. The upper and lower water valves are leaking, the upper water valves are also leaking, and the water pipe has no water for a long time, resulting in water backflow, which needs to be repaired and solved.

5. The sprinkler valve or hot water nozzle is out of order, and it is not actually opened, and it needs to be repaired.

Summary. It is normal for the evaporated water vapor to condense into water and flow down.

Good. Hello, is this water large.

If it's a small amount.

Leak big. It is normal for the evaporated water vapor to condense into water and flow down.

If there is a lot of leakage.

1. The valve for water supply is not closed strictly, which always leads to slow water supply, you can try to close the main valve at home and then turn on a cold faucet. 2. It may be that the small leather cushion on the return pipe in the water tank is a problem with relatives. 3. The solar overflow pipe has been overflowing outward

It is the water that is full before the water flows. Explain that the system also talks about adding water. It may be that the water filling valve is out of order.

There are three of these. Possible.

You can pay attention to the check.

Yesterday the sun was very strong, and the cold water went down, and there was no hot water to bathe.

I'm adjusting the water automatically.

That should be the valve that you automatically put on the water is loose.

Oh. It is better to apply the water automatically or manually.

It must be good to automatically water feeding, which is convenient and trouble-free, but many times there will be a little problem.

We hope you are informed.

Hello, glad to answer for you. [Flower segment]. The solar overflow cannot be plugged.

The solar water heater water tank, the upper and lower water is a pipe, and the exhaust hole must be set on the upper part of the water tank to effectively ensure that the air in the water tank can be discharged. In fact, the function of the overflow port is equal to the intake and exhaust port, after blocking, the water tank method intake and exhaust, due to the effect of atmospheric pressure, the water tank can not discharge water normally. If the overflow of the solar water heater used at home is blocked, be sure to dredge it in time.

Ways to solve water leakage: 1, water pipe and joint leakage, if it is a hot melt pipe, it is caused by a bad grip of the hot melt connection, and it needs to be re-melted, if it is an aluminum-plastic pipe, it may be that the screws are not tightened or damaged, and the pipe needs to be replaced. 2. The leakage of the joint and water tank pipe may be caused by damage to the raw meal belt, resulting in water leakage.

3. If the water tank pipe and water tank are leaking, if it is a welded type, the water tank needs to be replaced, and the argon arc welding master should be found, and the insulation layer should be opened and re-welded. 4. Silicone sealed leakage, change the sealing ring, or you can replace the sealing ring of the exhaust port on the solar top for use.
