Faced with a variety of pure water equipment, how should we choose and maintain pure water equipment?
High pressure pump does not stop
1. The high pressure pump pressure is insufficient, can not reach the high pressure set pressure
2. The check valve is blocked and does not produce pure water
3. High pressure failure, unable to jump
When the water is full, the machine jumps repeatedly
1. Raw water pressure is insufficient
2. Relieve pressure from check valve
3. The high pressure switch or liquid level switch is faulty
4. The system has depressurized
The high-pressure pump is working, but it can't make water
1. The high pressure pump loses pressure
2. The inlet solenoid valve is faulty and cannot enter water (neither pure water nor wastewater)(Whether it is reversed).
3. The pre-filter element is blocked (no pure water wastewater or very small wastewater)
4. Check valve failure (waste water without pure water)
5. The automatic flushing solenoid valve fails and cannot be effectively closed (it has been in the flushing state)
6. The backflush solenoid valve cannot be closed if the computer case is faulty (it has been in the flushing state)
7. The RO membrane is blocked
Pure water flow is insufficient
1. The front filter element is blocked
2. The high pressure pump pressure is insufficient
3. The RO membrane is blocked
4. The waste water valve or waste water proportioner is too open
5. Retroactive carbon plugging
6. The pressure bucket has insufficient pressure or internal damage
High pressure pump does not start, can not make water
1. Check whether the power is off and the plug is plugged in
2. Check whether the low-voltage switch is faulty and cannot be turned on
3. Check whether the water pump and transformer are short-circuited, or the circuit connection is incorrect
4. Check whether the high pressure switch or water level controller is faulty and cannot be reset
5. Check whether the computer case is faulty
The high pressure pump stopped, but the waste water didn't stop
1. Solenoid valve failure, can not effectively cut off water
2. The computer box is faulty, and the solenoid valve cannot be closed (refers to the microcomputer type).
3. Pressure relief of check valve (small wastewater flow)
