Why is my water filter running slowly? Discover the causes and solutions now.

2. Water Leakage

Similar to the unstable inlet water supply, water leakage also results in insufficient water for smooth operation of the RO clean water filter, reducing filtration speed and causing the issue of slow-running water filters.

Water leakage causes slow-running water filters

Solution: In this case, you need to check all water valves, faucets, and connections between the filters to detect leakage points. If the leakage point is too large and cannot be fixed with simple actions such as tightening valves, you need to replace the leaking component. Especially, as the household RO water filter system uses electricity, you should disconnect the power supply of the machine before inspection to ensure maximum safety for yourself.

3. Clogged Water Filter Cartridge

Not only a common answer to the question of why water filters run slowly, the condition of a clogged water filter cartridge is also the cause of many other issues in water filters such as continuous shutdowns, no water output, etc.

5. The faucet is blocked or damaged.

The ultimate reason why water purifiers run slowly is because the valve is blocked or damaged. Over time, due to the specific pressure of the flowing water in the clean RO water purifier, this pressure can cause the valve foot to loosen. Additionally, the valve can also become clogged with dirt over time, due to installation errors or long-term operation weakening or damaging the valve.

All of these reasons can lead to the situation of the water purifier running slowly due to the valve. If the valve is loose due to prolonged water pressure, you can tighten it back. If the valve is dirty, you need to clean it thoroughly to resolve the blockage. If the valve is weak or damaged and cannot be fixed, you need to replace the part.

However, in general, the reasons leading to this slow-flowing water purifier are quite complex, therefore, you should seek the support of a technician rather than attempting to fix it yourself following the instructions to repair the RO water purifier above.

In general, slow-flowing water purifiers are very likely to occur with old water purifiers that have been used for a long time. Therefore, you need to be very careful when buying second-hand water purifiers because the internal parts may be significantly damaged, and the filter core may have expired. Instead, you should consider purchasing a good quality water purifier from reputable brands.
