Everything is hydrated and silent, and the water flows smoothly throughout the body, keeping everything in balance. When it comes to staying healthy, drinking clean, pure water is essential. It should be free from pollution, coloring, and any unnecessary additives.
If you're serious about living a healthy life, having a water purifier at home is a smart choice. More and more households are adopting these devices quickly, but with so many options available, consumers often find themselves confused when choosing the right one.
Many people don’t know where to start or how to make an informed decision. That’s why we’re here to guide you through some of the most important protection features of a reverse osmosis water purifier.
A pure water machine is commonly referred to as a “plug-in water purifier†by everyday users. These devices are designed to ensure that the water you drink is safe and clean. But behind the scenes, there are several critical safety mechanisms that help keep the system running efficiently and safely.
Low Voltage Protection
Low pressure protection is one of the first lines of defense in a water purifier. It prevents the pump from running dry when there's no water supply, which can damage the pump over time. The low-pressure switch typically activates when the water pressure drops below 0.05 kg. At this point, the system will automatically stop to protect the internal components.
Note: Self-priming models may not require this type of protection, so it's important to check your specific model's specifications.
Inlet Protection
Inlet protection ensures that the water purifier only opens the waterway when it's actively producing purified water. Once the system stops, the inlet valve closes to prevent tap water from flowing back into the unit, which helps save water and avoid contamination.
The quality of the inlet solenoid valve is crucial here. It needs to be both sensitive and able to withstand high pressure to function properly over time.
Wastewater Protection
Wastewater protection plays a key role in the cleaning process of the reverse osmosis membrane. During the flushing cycle, the system fully opens the wastewater channel to rinse out impurities trapped on the membrane, which helps extend its lifespan.
When the system is producing water, another wastewater channel remains open to maintain the necessary pressure for efficient filtration. This ensures consistent water output and better performance.
The sensitivity of the wastewater solenoid valve and its ability to handle two different pressures (flushing and wastewater) are vital. Therefore, the overall quality of the wastewater valve is a major factor in the reliability of the entire unit.
High Voltage Protection
High voltage protection is essential to ensure the system shuts down properly once the purified water tank is full. Without this feature, the pressure tank could overpressurize and potentially explode, posing a serious safety risk.
The sensitivity of the high-pressure switch and its durability are key factors in ensuring safe operation. Some brands use cheaper switches to cut costs, but this can increase the risk of failure. A reliable high-voltage protection system is crucial for long-term safety and performance.
Pump Constant Pressure Protection
To operate effectively, the reverse osmosis membrane requires a consistent pre-membrane pressure of around 6–8 kg. A stable water pressure ensures that the system produces water consistently and extends the life of the membrane.
While standard pumps may experience significant pressure fluctuations, a high-quality pump maintains a more stable pressure over time. Poor-quality pumps tend to lose pressure quickly, which can reduce efficiency and shorten the lifespan of both the pump and the membrane.
As you can see, choosing the right water purifier involves understanding these important safety and performance features. With the right knowledge, you can make a more informed decision and enjoy clean, safe water every day.
