What brand of household water purifier is good? It's important to master the method.
First, look at the qualifications. The Health Supervision Center of the Ministry of Health of the People's Republic of China has clearly issued the measures for the supervision and management of drinking water hygiene. Consumers can go to the public network of health administrative licensing for inquiries when purchasing.
Second, look at the material. Materials such as stainless steel, fiberglass, cast iron, aluminum, food-grade resin or PVC are currently available on the market. The first three are materials with good pressure resistance, which can be used as pre-filters (** machine).
The latter two are materials with poor pressure resistance, and can only be used at the back end of the pre-filter (** machine) and used as a direct drinking machine. Among these materials, the compressive resistance and corrosion resistance are relatively high for the purpose of stainless steel, and the compressive resistance of food-grade resin or PVC is poor, and the compressive resistance is relatively low.
3. Define the function. When choosing a water processor, you must first clarify your purpose, first of all, in terms of the big concept, whether you want to purify water or soften water. Purified water is to remove sediment, impurities, bacteria, heavy metals, residual chlorine, organic matter and some minerals from water.
Demineralized water is the removal of calcium and magnesium ions from water.
Fourth, the selection of filter material. At present, the commonly used water purification materials mainly include PP cotton, activated carbon, KDF, ultrafiltration membrane, RO membrane (reverse osmosis membrane, reverse osmosis membrane), quartz sand, maifan stone, infrared mineralization ball, etc. Different water purification materials will produce different purification effects, and consumers can choose a suitable water purifier according to the purification effect they want.
Fifth, the size of the ratio. Water purifiers are generally based on the instantaneous water output to determine the model, more than 20 tons of hours can be called ** water purifier, less than 10 tons of hours can be called direct drinking water purifier. And this water output is related to the volume and the diameter of the water inlet and outlet, usually the larger the water purifier, the larger the instantaneous water output.
Sixth, than the service. The first is the pre-sale service for the installation of water purifiers, according to various factors such as different regional water quality, different waterway design, different room sizes, etc., we should give a more complete purchase suggestion and ask about the use effect after installation, and then make improvements according to the customer's requirements. In addition, leakage caused by various reasons in the use of water treatment materials is possible, so it is also necessary whether the water purifier is insured by the insurance company.
As the saying goes, "if you are not afraid of 10,000, you are afraid of what if", when there is an accident, the insurance company will pay according to the customer's loss.

Half of this is the case when the motor is broken, or the RO mold is blocked.

Reasons and solutions for Qinyuan water purifier not to produce water: lack of water, or water has been stopped. If there is a shortage of water, check the water supply pipeline, whether there is maintenance, or ask the water supply company.
Some water purifiers need to be restarted to run after the water is off, you can try to turn off the power and restart again. If there is no water pressure gauge, you can open the faucet and block the water by hand, if it can be blocked, it is not enough water pressure. Filter element clogging (including PP cotton, activated carbon, RO reverse osmosis membrane will be blocked, the most common is PP cotton blockage.
Use the manufacturer's wrench to open the filter shell of the PP cotton and check whether it is stained with mud and other debris that obstructs the flow of water. The same goes for activated carbon filters. If these two things are normal, the water pressure is also normal, the machine is started, and the water pump is working, it is the RO reverse osmosis membrane blocked.
RO reverse osmosis membrane makes the period of use of radical is generally 12 months. The inlet valve is broken, sometimes due to foreign objects stuck, resulting in the inlet valve not working, sometimes it is a problem with the circuit, which needs to be carefully checked. If you find a problem, it's best to replace it with a new one.
Low pressure valves, high pressure valves, bad low pressure valves, and high pressure valves are a switch that starts and stops, and is connected in series in the circuit. No matter which one is broken, it won't start. The low-pressure valve is a normally open contact, and the high-pressure valve is a normally closed contact, which can be measured with the help of a multimeter.
Also check if the circuit is disconnected. If the pump is bad and the normal water purifier is working in imitation, we will hear the sound of the water pump, if there is no working sound of the water pump, it may be that the water pump is malfunctioning. Check the power supply line, if the power supply is normal and the pump is not working, it is recommended to try a new one.
The most common reasons are the above. If it is a problem with the motherboard, basically there is only one way to call ** for after-sales service.

If the RO machine does not make water, it may be that the power supply is broken, so try to change the power supply; If the power supply is excluded, it should be that the electric pump is faulty or the solenoid valve is faulty, which is more complicated, and it is recommended to contact the brand after-sales.
Check the transformer, if the solenoid valve and the motor work together, stop together, prove that there is still no power supply, connect the pump with a transformer separately to see if it will work, if it will work, check the binding post of the low-voltage switch, the connector of the binding post will sometimes clamp the insulating rubber. Take a look at the new connection between the binding post and the power cord.
Products. Qinyuan water purifier can effectively remove chlorine, heavy metals, bacteria, viruses, algae and solid suspended matter in the water, and the post-activated carbon filter element will further remove various organic matter in the water, making the treated water clear, clean and sterile. The automatic maintenance function unique to the automatic water treatment controller can restore the water purification efficiency of the entire system at regular intervals.
Therefore, the system has long-term, continuous and stable purification capacity, and the self-cleaning water purifier does not need to replace the filter element frequently, which greatly reduces the operating cost. The controller adopts self-priming control for the water flow, and the water pressure before and after treatment remains unchanged to ensure the stability of the user's water consumption during the peak water consumption period.
Qinyuan water purifier has a delicate appearance: according to the use space conditions required by different users, the system can be connected in parallel or series with multiple devices to increase water production or further improve the effluent quality. The patented design of the fuselage structure ensures high flow rate, stable water pressure, and DC instant processing function.
Food-grade FRP buckets meet the independent, individual, and environmental protection needs of future household products.

There are several reasons why water is not made after cleaning, and it is normal not to make water. First, maybe the filter element you installed was not installed correctly, and did it cause the pipeline to be blocked? Second, when disassembling and cleaning, did you break the pressure switch?
It's important to check if your pressure switch is working properly, sometimes it's stuck. The normal situation is that the pressure is low and the conduction is on, he starts to make water, and the pressure is high and stops, you can see if the switch action is normal. Also, check if the power supply is normal.

1. Check the pipeline of the water purifier, straighten out the pipeline of the water purifier 2. Check the power supply of the water purifier, turn on the alternating current of the water purifier, and check the output voltage of the transformer if the input power supply of the water purifier is normal. 3. Check whether the high-voltage switch or float switch is out of order and cannot jump back. 4. Check whether the water inlet solenoid valve is normal.
Unscrew the water outlet of the solenoid valve, turn on the power supply, check whether the water is passed, if the water is not passed, turn to the next step to detect 5, open the raw water ball valve, and detect whether the filter element before the reverse osmosis membrane is blocked, such as replacing it with blockage; If the water is passed, the solenoid valve is damaged6, check whether the pressure after the booster pump reaches the requirements. If it is lower than the need to replace 7, open the pure water port of the reverse osmosis membrane, if the water does not come out, the reverse osmosis membrane is damaged 8, check whether the wastewater discharge is too large, so that the proportion of pure and wastewater is out of balance 9, check whether the rear activated carbon filter element is blocked.

Hello, dear, very happy to answer for you! Here's the answer, check it out! The common reasons why Qinyuan water purifier does not make water are:
1.The power supply is not connected: When the power cable is reversed, it will not work normally, check whether the power supply is reversed.
2.The water level is too low: The indicator light will turn on, but no water is coming out, which may be due to the poor connection between the water purifier and the water source, or the water level is too low.
Just correct the water level. 3.Clogged filters:
Change the timing of the water purifier filter element, if you do not change it for a long time, the filter element is easy to become dirty, and the water resistance increases, resulting in the inability to make water. 4.Circuit Fault:
Check for disconnection and damage to the circuit, as well as poor plug contact, and repair the damaged part to restore normal. Data expansion: Water purifier, also known as water purifier and water purifier, is a water treatment equipment that deeply filters and purifies water quality according to the requirements of water use.
The water purifier that we usually talk about generally refers to a small purifier used for home use. The core of its technology is the filter membrane in the filter element device, and the main technology is ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane. Your questions have been answered!
