    • Great tank- revitalize your R/O system!
If your system isn't performing/making water like it used to...this nice tank may be what you need to bring it back to life! Easy to connect- really! Note: it has 1/4" tube valve, and mine has 3/8"...not an issue- just get a new valve with right size (Amazon has them for 7.99). You can do it- buy it...try it- and call their customer service if you have any issues- very helpful. ... show more

    • Worked perfectly
Tank came with 1/4 “ valve. I needed 3/8 “ for my system. Ordered from Amazon and arrived next day. Tank comes pre pressurized. Don’t need to mess with it. Hookup water line to tank and open system. Takes 1 or 2 hours to fill system. Faucet delivers proper water pressure.

    • Lowest priced and it worked
I chose this one because it was the lowest-priced Amazon option. It worked perfectly because it's a commodity item unseen under the sink. More expensive options wouldn't work any differently

    • Easy install
If you have no water pressure this is possibly a cure. I had a leak so water came out of the air valve. So if you see this get a new tank like this. First though, you will need a little bit of teflon tape to wrap the threads for the water hose valve. But its easy to screw that on by hand. Instructions are clear to fill tank for two hours and then empty to flush the tank. I like that the tank was filled to 10psi so no adjustment needed. Quick note, a 4 gallon tank is actually 3.3 gallon capacity but this size tank fits inder sinks a little better. Anyways good tank! ... show more

    • Standard tank - meets expectations.
Updated Sept. 2023: The tank no longer works - water merely trickles out from my faucet. Lost pressure and won't hold when attempting to re-pressurize it so it seems like the bladder has ruptured. Original review Sept. 2021: Most of these tanks seem to be made by the same factory so I don't really think there's much difference between them. This brand had a good price and was in-stock for fast delivery. I swapped out my bad tank (ruptured bladder) with this new one in about 10 minutes and allowed it to fill and flushed it a few times before using the water. It comes pre-charged so you don't have to pump it up and includes a plastic stand which is convenient. I did have to swap the included fitting since my tubing is 3/8", not the standard 1/4". ... show more

    • WORKS GREAT!!
This tank works awesome, it's been a year since I purchased this. My uncle was unsure why his system started to have a slower flow, without hesitantation I'm here again. This time not only to leave a review, but purchase for him!!! I'm a avid purchaser, and I always do my research. So buy with confidence. And no I'm not a sponsor of the product. ... show more

    • Great replacement from my under-sink RO unit
After five years of service, the original accumulator tank for my under-sink RO unit had a failed bladder inside, which made the faucet output go to near zero immediately after you drew any water from it. This tank replaced it and got the faucet back to the proper water output level it used to have. Lots of RO water available again, any time you need it! This particular size tank appears to be very common to many different manufacturers' under-sink RO units, mine replaced a 3.2 gallon tank in a "Home Master TM" system. It even had the same RO132 part number on it. ... show more

    • Best Osmosis Tank
Just wanted to give credit where credit is due, like any other person it's hard to wake up and not be able to get your water in the morning. After testing and pressurizing the tank multiple times i found out it was my tank, I replaced it with this one tankPro ; let it fill up for 2 hours just to make sure it was nice and full and done. High pressure flow, easy to install, comes with new valve and stand to keep it of the wood board. Very happy with this product, I am a week in and still enjoying the tank. Highly recommended. ... show more
