Replacement for my RO system and this was an exact match. Works like a charm. I wanted to get rid of the entire RO system because I thought I needed to. I tried to put more pressure in my old tank and it turns out that the pressure chamber most likely had burst and decided to just get a replacement when black water came out of it when I was draining it (not drinking that!). Good product. Came pressurized already. Installed in five minutes and drinking water after about an hour to give it enough time to fill up fully. I recommend!

Worked great at first but I didn’t notice a leak behind the connector valve. Reconnected it after draining with the addition of plumbers tape and had no other issues. Would recommend.

I have an older but great RO system under my sink that I bought at Costco about 12 or more years ago.... it started to not give as much water and then none and after reading and researching I was fairly sure the bladder inside the tank was no longer working. I found this tank on Amazon which seemed to be the same one and crossed my fingers. It was an exact match and for $50 it was an easy fix! I had forgotten what a pain it was to lug bottled water from the store constantly, and was super glad after a week to have clean water accessible again in my kitchen!!!

This replaced my PureBlue H2O RO pressure tank. It is a bit lighter weight than I expected, but works well.

There are some reviews that mention receiving a dented cylinder - mine arrived in perfect condition. I guess that might be more a function of the delivery service vs. the manufacturer. Mine was delivered by Amazon delivery so kudos to Amazon. The install was incredibly easy and it totally solved my problem. All of a sudden I could only get about 13 fluid cups before water stopped flowing from my RO system. After the new tank was installed I now get approximately 50 cups. Search YouTube for some helpful hints on the swap out but again, don't be afraid to do this yourself. It is easy!
Great Job !

It's a replacement of our old tank. Did lots of research on how to install this RO tank. The old tank was down since water was not coming out of our faucet. After following the manual and added air to the tank, the water was coming out of the faucet. However at the same time water was coming out of the air pressure pin. After googling online for awhile, I wasn't sure if that's normal. But one article gave great explanation and informed that the bladder inside could start having pin holes after longevity of usage. From that information, I presumed that water was leaking into the bladder and hence water was pumping out of the pressure pin hole while I was pumping air inside.The new tank came packaged well. I also noticed it was made in Taiwan, as many products now a days are made in China. It's rarely not to see made in China. There are still good quality products from China, especially under foreigner management. However, very rare.I'm not sure the life expectancy of these tanks, as the vendor cannot tell me either. Only time can tell. I expect that it should at least last 8-10 years. All in all, if anyone were to have their RO tank down. I would recommend to buy here.
