– RO Water Filtration System Expansion Tank – 6 Gallon Water Tank -– Compact Reverse Osmosis Water Storage Pressure Tank with Free 1/4" Tank Ball Valve

I’ve had a RO system for many years and had a smaller tank on it. The bladder finally went and I decided to upgrade and it is performing very well. I followed the instructions to clear the tank after one minute of operation and then again after four hours of operation. There is no residual taste.When hooking it up to your system, I would make sure to just leave the pressure where it’s at as it is typical for most systems. If it doesn’t work for you then adjust it. Furthermore, when you put the Plastic valve on the top, I would use not only Teflon tape but also some dope as well.I had to return the first tank they sent as it was not wrapped well and came dented, but to be fair it did work for the short period of time before a replacement was sent, the company was quite responsive. As an FYI, the second tank came much better wrapped. It was undamaged. they had clearly realized they had a problem so they change the wrapping.

Excellent upgrade to our RO system. Old tank would barely fill a gallon, this bad boy fills 3+ gallons no problem. Easy to install although the tubing to my RO system was larger than the supplied valve, just used the valve from my old tank but make sure to measure your tubing.

Worked exactly as expected. Came with just the right amount of air pressure. Replaced a tank that was giving water a musty flavor - now the water tastes great!

Why did I not already have one of these?? It is so nice having this large resevoir so I can fill pasta pots, dog bowls, kids sports tumblers, etc. without having to stop part way thru and wait for it to refill. It fits nicely under my sink, but note that I have a center sink drain. It may not fit under a double sink with 2 drains. Measure twice before purchasing. Again, why did I not purchase one of these 15 years ago????

I wish I had replaced the original RO tank with this years ago. The original one always ran out with anything over normal use with three people. We haven’t run out of water yet with this one. Great for hosting.

2nd tank like this I've had. After delivery, I checked pressure and even through transit, pressure was still at 7 PSI which is awesome. Replaced defective tank and after two days found that the included valve is seeping water between handle and body. Old valve already by picked up by trash dude. Had to order one since HD, Lowes, and Ace don't carry it locally. Waiting game. Would recommend having a better valve on hand during install/replacement.

It worked like it should. This is great and I haven't had it leak yet. I will buy from you again.

Purchased and installed in December with new RO system and now it is March, and it no longer works. I switched to the smaller one that came with the system in purchased and it works fine. I will not buy again from this company as the return window was only until the end of January.
