With its streamlined design and simple installation, this mini RO storage tank aims to streamline your filtration workflow without crowding precious space. The result is a dependable reservoir that supports steady pressure and quiet operation, so you can enjoy clean water without the clutter.

Why it fits your RO setup

• Compact footprint ideal for tight spaces under sinks or inside cabinets
• Direct compatibility with most 1/4 inch tubing for easy integration
• Out-of-the-box 1/4 inch quick-connect to minimize plumbing steps

Setup you can follow

• 1/4 inch quick connect is ready; cut the RO unit outlet tubing and insert both ends into the tank
• If your pipe uses 3/8 inch, contact customer service for guidance
• Ensure the tubing is cut squarely and fully inserted to prevent leaks

Common checks for reliable operation

• Inspect the washer at the ball valve junction if you notice a leak
• If water does not come out or you detect slow flow, verify the interior membrane and charging valve
• For persistent issues, reach out to customer support for troubleshooting and guidance

Notes on compatibility and use cases

If you route water from the RO system to a refrigerator or other fixtures, consider using a bypass on the refrigerator filter to keep the main filtration path focused on the RO system. This helps maintain a clean and efficient flow for your primary filtration needs.
