Common faults and treatment methods of household water purifiers

Check whether there is a power outage (water outage) and whether the plug is plugged in.
Check whether the high-voltage switch or low-voltage switch fails.
Check whether the transformer and fuse are burnt out.
Check whether the microcomputer control box is faulty.
Check that the water source pressure is insufficient or water is stopped.
Check the high-pressure pump for a short circuit.
After the installation of the water purifier machine is completed (the high-pressure pump operates normally), water cannot be produced
Check whether there is a fault with the water inlet solenoid valve and the water cannot be fed (there is no pure water or waste water).
Check whether the first three filter elements are blocked (there is no pure water or little wastewater).
Check whether the RO membrane is blocked.
Check whether the high-pressure pump has lost pressure.
Check whether the flushing solenoid valve fails and cannot be effectively closed (it has been in the flushing state).
Check whether the check valve is blocked (whether there is wastewater or pure water).
3. The pressure water storage tank is full but pure water cannot flow out
Check whether the air in the pressure bucket is depressurized; Check whether the rear antibacterial activated carbon is blocked.
Check whether the pressure bucket ball valve is damaged.
4. The machine is in a shutdown state, but the waste water flow does not stop
Check whether the intake solenoid valve is damaged and cannot effectively cut off water.
Check the check valve for damage (low wastewater flow).
Check if the microcomputer control box is faulty and the solenoid valve cannot be closed.
Some basic principles for selecting water purifiers:
1. High cost performance ratio of water purification products: good quality and stable performance; Convenient to use; Low maintenance and operating costs; Strong professional skills and good after-sales service.
2. Soft water products are selected for domestic water and water with a certain hardness (140mg/L to 200mg/L) is selected for drinking water.
3. It is recommended to select a composite ultrafiltration machine in areas where the hardness of water is below 170mg/L.
4. In areas where the hardness of water is between 170mg/L and 250mg/L, it is recommended to use soft water for shower and laundry, and composite ultrafiltration water is recommended for direct drinking water.
5. For showers in areas where the hardness of water is above 250mg/L, it is recommended to use soft water for laundry. For direct drinking water, it is recommended to choose partially softened water (mixed with softened and unsoftened water in a certain proportion) that is filtered by a composite ultrafiltration machine.
6. For water in areas with high fluorine, salinity, and sulfur, choose a pure water machine as direct drinking water and supplement trace elements.
7. For areas with heavy groundwater or sand particles and rust, it is recommended to install precision filters after the master meter.
