Like my 5 gallon tank after 3 years will only fill a cup around 36 ounces of water before the water starts coming out slowly. I'm guessing this smaller tank will do the same in a few years, but right now it's running at high pressure for at least 3-4 minutes before moderately slowing. Dealing with replacing a smaller tank is just more convenient, but you aren't going to notice a difference in the output between a large and smaller tank for most applications. ## Features - 3.2 Gallon NSF Certified Tank - 1/4" Stainless Steel Water Connection - High-Grade Chlorobutyl Diaphragm - Virgin Polypropylene Liner - Pre-Pressurized / Pre-Charged ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079NH1XB6 | | Best Sellers Rank | #271,081 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #448 in Under-Sink & Countertop Filtration | | Brand | Hydronix | | Brand Name | Hydronix | | Capacity | 3.2 Gallons | | Container Type | Bottle | | Customer Reviews | 4.3 out of 5 stars 34 Reviews | | Included Components | Storage Tank | | Installation Type | Under Sink | | Item Dimensions L x W x H | 10"L x 10"W x 10"H | | Item Weight | 6 Pounds | | Manufacturer | Hydronix | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model Name | RO-122-W14 | | Model Number | RO-122-W14 | | Other Special Features of the Product | Heavy Duty | | Part Number | FBA-RO-122-W14 | | Product Dimensions | 10"L x 10"W x 10"H | | Purification Method | Reverse Osmosis | | Smart Home Compatibility | Not Smart Home Compatible | | Special Feature | Heavy Duty | | Supported Water TDS Level Maximum (PPM) | 500 | | UPC | 693614033054 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Hydronix - **Special Feature:** NSF certified - **Material:** Stainless Steel - **Capacity:** 3.2 Gallons - **Package Information:** Bottle - **Installation Type:** Under Sink - **Purification Method:** Reverse Osmosis - **Item Weight:** 6 Pounds - **Model Name:** RO-122-W14 - **Supported Water TDS Level Maximum (PPM):** 500 ## Images ![RO-122-W14 Hydronix 3.2 Gallon Stainless Steel Reverse Osmosis Storage Water Tank, Small Size - White, 1/4" Port - Image 1](https://m.media-amazon.com/images/I/51c5KKGTKlL.jpg) ![RO-122-W14 Hydronix 3.2 Gallon Stainless Steel Reverse Osmosis Storage Water Tank, Small Size - White, 1/4" Port - Image 2](https://m.media-amazon.com/images/I/51VKoeaANWL.jpg) ![RO-122-W14 Hydronix 3.2 Gallon Stainless Steel Reverse Osmosis Storage Water Tank, Small Size - White, 1/4" Port - Image 3](https://m.media-amazon.com/images/I/41KlS97WVIL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect tank *by A***R on December 17, 2025* This worked perfect ### ⭐⭐⭐⭐⭐ Small tank, high performance. *by K***S on March 17, 2025* I have used a 5 gallon tank over the years, but find they only last about 3 years with the membrane leaking, and available water storage being limited.
