NSF-Approved 6.5 Gallon RO Tank for Reliable, Clean Water Storage
When it comes to maintaining pure, fresh water in your reverse osmosis system, the NSF-6.5 NSF Approved 6.5 Gal RO Tank delivers unmatched reliability and safety. Designed specifically for residential RO components, this tank addresses common issues like contamination and inconsistent water pressure by providing a durable, NSF-certified solution that ensures your purified water remains clean and readily accessible.
Key Benefits
- Ensures consistent water pressure for steady flow at your faucet.
- Protects water purity with NSF-approved materials that prevent contamination.
- Offers ample 6.5-gallon capacity to meet daily household water demands.
- Durable white poly housing resists corrosion and extends tank lifespan.
- Compatible with a wide range of residential reverse osmosis systems.

How It Works
This 6.5-gallon reverse osmosis tank functions as a pressurized storage vessel within your water filtration system. After water passes through your RO membranes, it flows into this tank where it is stored under pressure. The tank’s built-in bladder keeps water separated from the air, preventing contamination and maintaining consistent pressure. When you open your tap, the pressurized water is pushed out smoothly, ensuring you get a reliable supply of purified water on demand.
What to Expect
Immediately after installation, you’ll notice steady water flow and improved faucet pressure compared to systems without a proper storage tank. In the first days and weeks, the tank will stabilize, providing consistent delivery without fluctuations. Over time, this NSF-approved tank requires minimal maintenance—just periodic checks to ensure the pressure bladder is intact and the tank remains free of leaks, helping you enjoy long-term system performance and peace of mind.
