Faced with a variety of pure water equipment, how should we choose and maintain pure water equipment?

Faced with a variety of pure water equipment, how should we choose and maintain pure water equipment?

High pressure pump does not stop

• The high pressure pump pressure is insufficient, can not reach the high pressure set pressure
• The check valve is blocked and does not produce pure water
• High pressure failure, unable to jump

When the water is full, the machine jumps repeatedly

• Raw water pressure is insufficient
• Relieve pressure from check valve
• The high pressure switch or liquid level switch is faulty
• The system has depressurized

The high-pressure pump is working, but it can't make water

• The high pressure pump loses pressure
• The inlet solenoid valve is faulty and cannot enter water (neither pure water nor wastewater)(Whether it is reversed).
• The pre-filter element is blocked (no pure water wastewater or very small wastewater)
• Check valve failure (waste water without pure water)
• The automatic flushing solenoid valve fails and cannot be effectively closed (it has been in the flushing state)
• The backflush solenoid valve cannot be closed if the computer case is faulty (it has been in the flushing state)
• The RO membrane is blocked

Pure water flow is insufficient

• The front filter element is blocked
• The high pressure pump pressure is insufficient
• The RO membrane is blocked
• The waste water valve or waste water proportioner is too open
• Retroactive carbon plugging
• The pressure bucket has insufficient pressure or internal damage

High pressure pump does not start, can not make water

• Check whether the power is off and the plug is plugged in
• Check whether the low-voltage switch is faulty and cannot be turned on
• Check whether the water pump and transformer are short-circuited, or the circuit connection is incorrect
• Check whether the high pressure switch or water level controller is faulty and cannot be reset
• Check whether the computer case is faulty

The high pressure pump stopped, but the waste water didn't stop

• Solenoid valve failure, can not effectively cut off water
• The computer box is faulty, and the solenoid valve cannot be closed (refers to the microcomputer type).
• Pressure relief of check valve (small wastewater flow)
