Troubleshooting

Milky color water: The sediment filter may need to be replaced. Check the sediment filter to ensure it is clean and not blocked.

Air bubbles in the water: One common issue people may experience when installing their express water filter is air bubbles. This is caused by a vacuum forming inside the piping system, making it difficult for water to flow through properly. To address this issue, loosen the fittings on either side of your filter and turn on both cold and hot faucets to release any built-up air.

Noise from the system: If your express water filter system makes an unusual noise, it could be due to air in the lines. Air can become trapped after installation or when adding new filters. To help reduce this noise, purge the lines by running a complete cycle at least once. If this does not help, check all connections to ensure they are correctly fastened.

The small amount of water from the RO drinking faucet: If there is a small amount of water from the RO drinking faucet, it means the filter cartridges are clogged. To solve this problem, you will need to clean or replace the filter cartridges depending on their condition.

Slow production or no water: If you are experiencing a slow production of water from your filter or no water coming out, the filter may be clogged. In this case, you should take out the filter and check for any blockage in the system. If necessary, you can use an air compressor to blow out any debris causing an obstruction.
