Works great
I needed a replacement tank and I didn’t want to buy a whole new RO system. This is very small and takes up little space under the sink.

More pressure
Great replacement for geekpure setup. Easy to install and a lot more pressure at the sink.

⭐ 1-Star Review I bought this RO tank in August 2025, and the package arrived damaged and dented. The tank itself was slightly bent, but I didn’t complain at the time — I installed it and started using it. However, after only three months of use, the tank has completely failed. On December 2, water started coming out of the air valve (Schrader valve), which means the internal membrane is ruptured. The tank no longer holds pressure and is now unusable. For a product that is supposed to last several years, this is extremely disappointing. The build quality is very poor, and the early failure shows that the tank was defective from the beginning. I do not recommend this product.

Box came dented
We received this tank and the box was dented. When we opened it the tank was slightly dented as well. Thought we would give it a try to see if the dent was cosmetic. It was and no one will be looking at it in the cupboard. Seems to be doing the job.

A really great value for the money.
I recently installed a small reverse osmosis system under my sink and wanted to have a small reserve tank to make the system more user friendly. I did a lot of looking and comparing (as I always do) and found this tank to not by only the best fit, but by far the best value for the money. I allows me to draw over a gallon of purified water at a time. More than enough to fill any need. It's a nice small size and easily fit under my sink in the limited space I had available. It can also be mounted vertically or horizontally if need be.

Plenty of storage
Was worried this nicely compact tank would have insufficient volume for our daily uses. It was perfectly fine and worked very well.

Perfect size for under sink installation.
Great size and quality. 3 weeks in operation, no leaks, and great space saver. Also it was a breeze to install.
