High-grade butyl diaphragm. Nitrogen (N2) Air Filling Pre-charged to 7 psi with compressed nitrogen resulting in stable air pressure over a long period of time. Stainless Steel Connections 304 Stainless steel 1/4" NPT water connection and included 1/4" quick connect tank ball valve. Stainless steel air valve (schrader valve). Triple coated carbon steel shell for durability and years of rust free service. This tank is a key component in a reverse osmosis (RO) system, providing clean, fresh water for your refrigerator, ice maker, and other applications. It stores purified water produced by the RO system and delivers it at a consistent pressure. Key Features Durable Construction: The tank features a cold-rolled carbon steel shell for superior strength and longevity. To prevent rust and corrosion, the tank is triple-coated for years of reliable service. Premium Materials: The tank utilizes a 304 stainless steel male NPT connection for secure plumbing connections. It also boasts a high-grade butyl diaphragm and a polypropylene liner, both of which are rated safe for drinking water storage. The butyl diaphragm separates the air chamber from the water chamber, ensuring the water you consume is never in contact with air. Pre-pressurized for Convenience: The tank comes pre-charged to 7 psi (pounds per square inch), eliminating the need for manual pressurization before installation. This pre-charge ensures proper water flow from the tank to your RO system. Review: Hold 3.75 gallons at 70 PSI incoming pressure - This is listed appx 6 gallons usable. This is dependent on incoming water pressure. I have a regulator on my home water line set at 70psi and after all night refill after the second flush of the new tank I measured the amount of RO water the thank holds at 70 psi fill pressure, which was 3.75 gallons. This is to be expected with these type of tanks. There is a diaphragm in the center with 8 psi of nitrogen or just air depending on the manufacture below and your incoming RO water on top. The incoming water pressure pushed the diaphragm down against the gas pressure. When you used the water the gas pushes the diaphragm up sending the water out the faucet. With the narrow tall shape I assume the diaphragm is closer to the top as it must be completely pushed up to the outlet when empty of water. The placement of the diaphragm (surmising) reduces the amount of water that the thank can hold compared to a short stout tank. This is fine for me, I needed the narrow tall tank to fit my space and it has more than doubled what the 3.x gallon tank could provide, which it replaced. If incoming water pressure is more than 70 psi (max is 100 for this tank) I would bet it holds closer to what is advertised. This was a simple swap with the existing tank and does everything it is supposed to do. Just keep the fact you will probably NOT get 6 gallons our of this tank especially if you are on a well or other low pressure system. Hope that helps set expectations and you are not disappointed. Review: Easy to install. - Its so much better having a 10 gallon compared to the typical 3 gallon. We've used it for a week now with no issues. ## Features - Water Storage Tank: Pressurized Water Storage Tank works inline with your reverse osmosis (RO) water filtration system collecting and pressurizing purified water. - High Quality Water Filter Tank: FDA grade polypropylene liner, high-grade butyl diaphragm, and 304 stainless steel connection ensure the safety and durability of the pressure tank. - Stable Pressure: Pre-charged to 7 psi with compressed nitrogen, the ro water tank maintains stable air pressure over a long period of time and prevents waterlogging. - Easy Installation & Size Range: The reverse osmosis tank comes with a 1/4" NPT water connection and a 1/4" quick connect tank ball valve for easy installation and operation. - Performance Assurance: The reverse osmosis pressure tank's exceptional quality and performance are ensured, meeting the highest standards in the industry.
