Questions and answers
I have a 300 GPD Commercial RO system and it stop working, I replaced all the filters and it’s still not working. What can I do?
If your Express Water 300 GPD Commercial RO system has stopped working after replacing all the filters, follow these troubleshooting steps:
1. Check for leaks or moisture – Inspect the system carefully for any leaks or unexplained moisture.
2. Release trapped air – Gently tilt the system in different directions and then set it back in place to help release any trapped air.
3. Flush the system – Run the system for one hour or empty the water storage tank twice to remove any carbon residue from new or unused filters.
4. Check water pressure – Ensure the water pressure is within the system’s operating range (10–100 PSI). Use a pressure regulator if needed.
5. Verify the system is turned on – Make sure the red Feed Water Adapter Valve is turned on and supplying water to the system.
These steps address common issues related to filter replacement and system startup.
