Many families will encounter the problem of slow water production and smaller pure water volume when using RO machines. There are many reasons for this. It is definitely wrong to blame the RO membrane blindly. The following are some reasons summarized by the reverse osmosis systems supplier. You can check your RO machine by comparison.
1. RO membrane blockage.
This is the easiest reason.
2. The first few filters are blocked.
The tap water quality in many places was originally poor, and it is very common to block the first filter elements such as pipeline maintenance and flood, but many users of RO machines lack the awareness to change the filter elements regularly. You know, the filter element is very important for the service life of the RO machine. Don't wait until the first few filter elements are blocked to prevent water from flowing out, then it will be too late. Long-term fatigue work has caused irreparable damage to the pump, transformer and inlet solenoid valve of the RO machine.
3. Low temperature.
The water production rate of the RO membrane has a great relationship with the temperature, with the maximum heat not exceeding 40 degrees and the minimum not less than 5 degrees. Generally, the best temperature is 25 degrees Celsius. Based on 25 degrees, the water yield will be reduced by 3% for every degree of reduction. Therefore, the water production speed in winter is generally reduced by half or more than that in summer. Users in rural areas need to pay special attention to cold protection and freezing prevention. Sometimes the filter bottles and membrane shells will be damaged in winter, and the outlet of the concentrated water pipeline should not be placed outdoors in winter.
4. The pump pressurization is small.
Pump pressurization is small, which usually occurs in RO machines with a service life of more than two years or RO machines that are in a working state for a long time. Pump pressure loss is generally not easy to be found, but its direct manifestation is that the RO membrane gives little water or the RO membrane does not give water, so people can easily think that the RO membrane is blocked.
5. The transformer is faulty.
If the transformer is faulty and cannot provide the voltage required for normal pressurization of the pump, the rotating speed will be slow, the increased pressure will be small, and the pressurization will be small, thus the pressure required for running water to pass through the RO membrane will not be reached, and the water production will be slow at this time.
6. The inlet solenoid valve fails or is blocked.
If the purified water and concentrated water from the water purifier come out very little, after removing the clogging of the filter element, you can consider changing the inlet solenoid valve to see if it is blocked.
7. The check valve is blocked.
Sometimes the check valve will be blocked, but this rarely happens. During the inspection, the check valve can be taken down to check the water output. If there are obvious changes in the water output after removal and before removal, it means that it is really blocked.
8. Post-activated carbon blockage.
This situation usually occurs after the replacement of new post activated carbon. Because there is too much carbon powder, it has not been washed away. Therefore, the general granular activated carbon filter element cannot be filled too full (not to cut corners), and the filling space should be reserved to ensure water flow on the one hand and the activated carbon itself has an expansion coefficient on the other.
