What causes the water purifier to flow weakly and how to fix this problem? Next, Websosanh will advise and share experiences to identify the cause and how to fix it when the water purifier flows poorly!
Water purifier Weak flow is a problem that often appears in households. Correcting this situation will help the machine run more durable.
Signs that the water purifier has a weak flow or no flow
When you see the water purifier flowing 0.5 – 1 liter, it begins to weaken, and the amount of water entering the machine is also less than normal. This is a sign of a weak water purifier.
- In many cases, pure tap water still flows but the amount of water is very small, and after a while the water stops flowing.
- Another worst case scenario is that no pure water comes out of the water purifier. When the faucet is turned on completely, there is no filtered water.
Cause of this condition: The inside of the filter elements may be clogged, preventing water molecules from passing through, or a part may be damaged.

According to research, water purifiers flow weakly or are clogged and do not produce water evenly, mainly due to the following reasons:
1. Coarse filter element is clogged
Since the main job of the prefilter is to filter contaminants larger than 5 micrometers in size, a common cause of a water purifier’s weak flow is a clogged prefilter. Normally, the pre-filter element should be replaced after 3 to 6 months of operation to avoid dirt build-up, clogging of the filter holes in the membrane, and poor flow from the water maker.
If you have determined that the cause of your water purifier’s weakness is due to a clogged filter element, you can fix it by replacing a new filter element.
To overcome this situation, you need to change the filter core from core 1 to core 4 regularly so that the quality of the output water source is always guaranteed. When buying filter cores, you should choose a reputable place to avoid buying old, cheap filter cores.

2. The pressure tank has run out of compressed air or is punctured
An empty or punctured pressure tank is also due to not changing the water filter regularly. When troubleshooting this error, you also need to make sure to check the pressure tank. If the pressure tank is rusty and has holes, you should immediately replace it with a new one so the water can flow strongly.
Solution: To fix this error, you need to pump air into the pressure tank or immediately replace the pressure tank with a new one to make the water flow stronger.

3. The water pump is weak and cannot transport water
Cause: Mission of water pump is to transport water to the filter cores. When the pump pressure is weaker than normal, there is not enough force to push the water through the filter core, causing the water purifier to flow weakly and leak. This is a rare phenomenon but is still one of the leading causes of errors that cause weak water flow in water purifiers.
Solution: Need to replace the family water pump, this is the best solution to fix this error. In case you cannot replace it yourself at home, you should contact a technician for inspection and repair!
4. The pressure of the input water source is weak
Cause: The water purifier operates due to water pressure. When the input water pressure is not strong enough to create a water jet, the water purifier will flow very little or even no water.
Solution: You need to immediately equip a water pump system for the water purifier to ensure that the water pressure flowing into the purifier is always stable.
5. The hot/cold water faucet is leaking
Cause: The faucet leaks due to tightening too much, causing the faucet latch to rise or fall. The latch is not tight enough, causing the faucet to be in a half-closed, half-open state.
How to fix: Need to loosen the screw at the bottom of the glass a little, hold the latch tightly, not too tight, not too loose, make sure the latch is horizontal, fits properly, not too high or too low.
