During usage, water filtration machines may suddenly generate loud noises, experience slow water flow, or leak... Below is a compilation of common issues with RO water filtration machines and their remedies.
1. Water Leakage in Various Types of Water Filtration Machines
Cause:
Some users of RO water filtration machines may encounter water leakage during usage. The common causes of water leakage when using various types of water filtration machines are improper installation. Loose screws, missing gaskets at the filter columns, or damage caused by animals biting through the water lines can all be causes of water leakage.
Resolution:
When facing this issue, you need to unplug the power, shut off the water valve supplying the water filtration machine, and check where the water is leaking. If the water is leaking at the connection point, you need to tighten the screws and check the gasket. If the water is leaking at the filter columns due to loose columns, you need to contact for filter column replacement.
2. Loud Noise from RO Water Filtration Machines During Operation
Cause:
If your household's RO water filtration machine is emitting loud noises during operation, the cause could be machine error. You may have forgotten to install the RO membrane or the improper installation process has caused the water filtration machine to trap air; the solenoid valve vibrates and hits other components. Additionally, if the noise comes from the pump, the cause may be a damaged flange screw or a faulty pump.
3. Common Issues: RO Water Filtration System Not Running and No Water in Tank
Cause:
Water filtration systems may face issues of not running and having no water in the tank due to reasons such as: water source for the water filtration system running dry, water supply valve being stuck, loose electrical connections, faulty low-pressure valve, faulty high-pressure valve, or burnt transformer.
Resolution:
When the RO water filtration system is not running or experiencing no water in the tank, you need to troubleshoot by checking the water supply valve and water tank; check the power outlet. If the cause is due to the low-pressure valve or high-pressure valve, you need to check by testing turning off the low-pressure valve and high-pressure valve; if the water filtration system runs when the low-pressure valve/high-pressure valve is turned off, it indicates that the low-pressure valve/high-pressure valve is faulty.
In the case of a burnt transformer, to check, you need to use a voltmeter or substitute device for various types of water filtration systems.
4. No Pure Water When Using RO Water Filtration System Faucet
Cause:
The phenomenon of no pure water even though you have activated the RO water filtration system may be due to reasons: tank pressure valve locked, no water supply, machine trapped air, damaged filter core, clogged RO membrane, or weak pump.
Resolution
Depending on the cause of the lack of pure water when using various types of water filtration systems, you have different troubleshooting methods. You need to open the tank pressure lock valve if it is locked, check the water supply; remove the RO membrane container to release air if the clean water and waste water have a lot of air bubbles due to machine trapped air.
In the case of damaged filter cores, you need to check by removing each filter core to see how the RO water filtration system operates, if the pure water comes out in a small, even stream, it indicates that core is damaged. Additionally, in the case of a clogged RO membrane, you will encounter a situation where there is a lot of waste water without pure water, then you need to replace the RO membrane.
For weak pumps causing no pure water when using various types of water filtration systems, you need to check with a voltmeter or manually test (use your hand to cover the inclined 45-degree conduit) and replace the pump.
5. Peculiar Smell, Sour Taste, or Water Heating in Purified Water
Cause:
The presence of unusual odor, sour taste when using RO water filtration machines may be due to the water container not being clean, lack of filter cores or damaged RO membranes, or the RO water filtration machine overheating due to continuous operation for a long time.
Resolution
If purified water has an unusual odor, you need to check the water container and inspect the waste water line along with the purified water line to see if they are installed correctly and check if the filter cores, especially the RO membrane, have expired.
If purified water tastes sour after using various types of water filtration machines, you may consider adding sour-removing filter cores. As for cases where purified water is heated due to continuous pump operation, you can use a different water container (the water temperature will return to normal) and review the machine's running instructions.
6. White Sediment in Purified Water After Passing Through RO Water Filtration Machine
Cause
The source water may contain high levels of lime or using inappropriate mineralization cores may be the cause of white sediment in the water.
Resolution
You need to check the water supplied to the RO water filtration machine by using that water to boil and see if there is a lot of lime sediment. If the water contains a lot of lime, you should use a cation core and add an automatic RO membrane cleaning system to ensure purified water and protect the RO membrane.
7. No Pure Water Despite Full Water Tank
Cause:
When the pressure in the tank is insufficient or the post-treatment core is blocked, you may encounter the situation of not getting pure water despite the water tank being full when using the RO water filtration machine.
Resolution:
If the post-treatment core is blocked, you need to remove the post-treatment core to check if the water flows normally and replace the core. If the tank pressure is insufficient (below 5 PSI), you need to pump additional air or replace the pressure tank.
8. Continuous Operation of RO Water Filtration Machine Without Shutting Off
Cause:
When using various types of water filtration machines, you may encounter the phenomenon of the RO water filtration machine running continuously without shutting off, causing machine overheating, noise... The cause may be weak water pressure and flow rate, machine trapped air, clogged pre-filters (filters 1, 2, 3), weak pump, clogged RO membrane, insufficient tank pressure, faulty check valve, or excessively adjusted high-pressure valve.
Resolution:
When facing this issue, first check the water pressure supplied to the RO water filtration machine, if the pressure is below 3m of water, you need to raise the water supply tank. In the case of the RO water filtration machine trapped air, you need to release the trapped air. If the RO water filtration machine still cannot resolve the above issue, you need to check the pre-filters and RO membrane, measure the air in the pressure tank, and reduce the high-pressure valve by 1 - 2 turns if the high-pressure valve is improperly adjusted.
