We've used it for a week now with no issues. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Hold 3.75 gallons at 70 PSI incoming pressure *by A***S on Reviewed in the United States on September 12, 2023* 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. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Love the extra capacity. Easy to setup *by S***N on Reviewed in the United States on June 26, 2023* Easy to setup. Bought the 10 gallon to upsize a 4.5 gallon. Very easy to swap out and then let it fill and drain 3 times before using. The extra capacity is exactly what we needed for a family of 5, and sometime a few guests. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/242573857-pressurized-water-storage-tank-reverse-osmosis-water-tank-with-stainless](https://www.desertcart.hr/products/242573857-pressurized-water-storage-tank-reverse-osmosis-water-tank-with-stainless) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
