Perfect replacement/upgrade
Works great, even better than the original glacier bay that came with my RO system.

Simple and works for good price
Simple hookup. Works great! Eliminated pulsing (on/off) of a tankless/pumped RO water filter system connected to fridge and coffee maker. Now I have good pressure at every fixture served by RO water filter system

Perfect storage tank for RO syatem
Perfect tank for an under the sink RO drinking water system. Has excellent pressure right out of the box, no need to pressure charge. Very easy to install.

Good product
Even though I didn’t buy the already used option. Once I got the box I could tell it had been returned by the tape job on the box. When I opened the box the tank had a small dent in the side. It wasn’t anything that affected the functionality of the tank so we kept it since we were ready to have our drinking water back.

Improved RO pressure
This was a simple installation and I liked the price. RO is now working again. I had little to no pressure and replacing the tank fixed my issue.

Excellent taste
Excellent pressure and more flow (better than our original), better taste, more capacity - love it. The excellent taste is what’s most impressive
