Troubleshooting Strategies for Home Water Purifiers, a Practical Guide to Help You Solve Problems

The working principle and role of home water purifiers
Household water purifier mainly through physical filtration, chemical adsorption and membrane separation and other technologies to purify water. Linear carbon water purifier uses the adsorption effect of linea carbon to remove chlorine, heavy metals and other pollutants in the water; reverse osmosis water purifier with the help of a semi-permeable membrane, which can effectively filter out bacteria, viruses, heavy metals and other harmful substances in the water, to provide families with more pure drinking water; ultraviolet water purifier using ultraviolet irradiation to kill bacteria and viruses in the water, suitable for the cleaner areas of the water source; ion exchange water purifier is mainly used to remove hardness ions in the water to improve the water quality, and to improve the water quality. Ion exchange water purifier is mainly used to remove hardness ions in water, improve water quality, especially for hard water areas.

It is applicable to a wide range of scenarios, whether for daily drinking, cooking, soup, or washing vegetables and fruits, etc., can let us use cleaner, more assured water, guarding the family's drinking water safety and health.

Home water purifier common faults and solution strategies

High-pressure pump does not start, can not make water:

first check whether the power outage, whether the plug is plugged. If the power supply is normal, and then check whether the low-pressure switch is out of order, can not be connected to the power supply; may also be a short circuit of the pump and transformer, or the whole machine line connection error; also need to check whether the high-pressure switch or water level controller is out of order, can not be reset; for microcomputer-type water purifiers, the failure of the computer box may also lead to this problem.

High-pressure pump works normally, but can not make water:
it may be a high-pressure pump pressure; water solenoid valve failure can not enter the water, need to check whether the connection is reversed; pre-filter cartridge clogging will lead to pure water wastewater or wastewater is very small; the backstop valve failure will be wastewater no water; automatic flushing solenoid valve failure, can not be effectively shut down, the machine has been in the state of flushing; the computer box failure can not shut down the backwash solenoid valve can also be seen in this linea situation! RO membrane clogging is also one of the common reasons.

High-pressure pump does not stop:
high-pressure pump pressure is insufficient, can not reach the high-pressure set pressure; backstop valve clogging, not out of pure water; high-pressure failure, can not jump; solenoid valve failure, can not be effectively opened, etc. may lead to the problem.
High-pressure pump shutdown, but the wastewater does not stop: solenoid valve failure, can not effectively cut off the water; computer box is faulty, can not shut down the solenoid valve; inlet solenoid valve is not closed tightly, or installed reverse, the backstop valve back to the water, etc. linea situation need to be considered. Can be judged by closing the storage bucket ball valve, observe whether the wastewater flow stops.

After the water is full, the machine repeatedly jumps, the frequency is faster and can not be completely stopped:
raw water pressure is insufficient, the backstop valve pressure relief, high pressure switch or level switch failure may be the culprit.
Pressure bucket full of water, but the pure water can not flow out: pressure bucket air pressure leakage, after the living linea carbon clogging, pressure bucket ball valve damage, etc. need to check.

Insufficient pure water flow:
the first three filter cartridges clogging, high pressure pump pressure is insufficient, RO membrane clogging, wastewater ratio is out of adjustment or wastewater valve is not closed tightly, the rear of the living linea carbon clogging, pressure drum pressure or internal damage, the water temperature is too low, too low pressure of the raw water, etc. may affect the flow of pure water.

Water leakage near the pipe interface:
check whether the PE pipe head cut flat, whether the pipe plug is plugged into place, whether the screw is tightened.

Abnormal noise during the operation of the water machine:

whether the backstop valve failure or aging, booster pump quality problems, raw water pipeline breakage caused by the booster pump idling, gas in the water, the water pipe is too long pump vibration so that the water pipe knocking the casing and so on may lead to a lot of noise.

Household water purifier maintenance and maintenance
In order to reduce the occurrence of failures and extend the service life of the water purifier, routine maintenance is essential. Regular replacement of the filter is the key, PP cotton filter is generally replaced once every three to six months, the living linea carbon is replaced once every six to nine months, the ultra-filtration membrane or RO membrane is replaced once every two to three years. After use, the ultrafiltration membrane should be kept in a moist state to avoid drying out, resulting in a decline in water production and can not be restored.
A good water purifier usually has an automatic flushing device, should be checked regularly to prevent clogging of the sewage outlets, if the sewage outlets are clogged will not only shorten the life of the filter cartridge, but also reduce the quality of water and cause secondary pollution. At the same time, the water purifier should be placed in a dry, ventilated place, avoiding direct sunlight and humid environment.

Frequently Asked Questions about Home Water Purifiers
- Q: What if the water purifier does not produce water?
A: First check whether the faucet switch is on, and then check whether the water pressure is too low, if the water pressure is low, consider installing a booster pump. Also need to check whether the cartridge is clogged, whether the water inlet pipe is clogged, whether the reverse osmosis membrane is damaged or aging, whether the auto-stop function is malfunctioning, whether the faucet or the valve is malfunctioning, whether the bucket is full of water, whether the power supply is normal and so on.

- Q: What should I do if the pure water tastes bad or has a bad odor?
A: Check whether the RO membrane filtration effect is reduced or failure, RO membrane shell of pure water and wastewater end of the partition or cracks, RO membrane size is appropriate or broken, after the role of the living linea carbon is effective.

- Q: the proportion of pure water and wastewater is seriously out of proportion how to do?
A: Check whether the flushing solenoid valve is damaged, whether the wastewater proportioner is clogged or too conductive, whether the RO membrane is clogged or the removal rate is seriously reduced.

- Q: What if the machine does not stop flushing?
A: It may be that the wastewater ratio is invalid or the flushing head is not tight.

- Q: What about the noise?
A: Check whether the raw water pipeline is disconnected, whether the raw water is normal, whether the booster pump failure, whether the water dispenser is placed firmly, whether the water pipe is too long.
      
    - Q: leakage how to do?
A: Check the water pipeline of the water purifier, find the leakage point, check whether the small connection is leaking, check whether the water dispenser is leaking. If the leakage point is not easy to check, use dry tissue paper to test.

- Q: What if the TDS value is too high?
A: First of all, test the TDS value of raw water, if the newly replaced reverse osmosis membrane needs to run for 20 minutes before measurement. Confirmation of the storage tank of pure water storage time is too long, such as the new replacement of the back of the living linea carbon also needs to be flushed. Also need to check the desalination rate of the RO membrane, RO membrane shell of pure water whether there are cracks, high pressure pump pressure is not enough, whether the raw water TDS value is too high, whether the pre-filter cartridge has not been regularly replaced.
      
    
 - Q: How to start the machine frequently?
   A: It may be that the backstop valve returns water and the high pressure switch pressure is set too high.
      
    
 - Q: The host starts in the automatic flushing linea, the pump will move and stop how to do?
   A: Insufficient raw water pressure or the first polypropylene fiber blockage caused by the press can be added or replace the cartridge.
      
    
      
 - Q: The machine is in a state of shutdown, but the wastewater flow does not stop how to do?
   A: The water inlet solenoid valve can not be blocked, can be disassembled to check whether there is debris stuck or damaged.
      
    
   When the home water purifier malfunction, do not panic, carefully observe the failure phenomenon, check and deal with the above strategies and guidelines, I believe that most of the problems can be solved, so that the water purifier continues to provide quality drinking water for the family.
