3 Gallon RO Expansion Tank – Compact Reverse Osmosis Water Storage Pressure Tank with Free Tank Ball Valve

Very pleased, product works well and was easy to install… this item was a replacement to original, replaced and works great!

perfect. was able to get the ro going in just a few minutes. also a good price

Replaced a 5-year-old tank that has minimal pressure. Super easy swap-out with the old tank, fully charged up in < 2 hours and easily and quickly yielded 2 gallons, versus the only tank would barely give me a quart. Good price, fast shipping. We'll see about longevity.

The media could not be loaded. We needed a smaller tank for our reverse osmosis system and this worked perfect. Fits under a Kohler farm sink in a standard 31 inch cabinet. Plenty of room and plenty of storage for water. We haven’t run out yet. A good solution to a 3 gallon tank.

I cant give a five star as I just baught it last one lasted 7 years but started to slow way down from what I have seen these last 2-5 years its a replaceable part that just wears out thats why I always have a spair on hand looks to be a good tank.

I don't have an osmosis system but the filters I have are exceedingly slow. I put this under the sink and it fits well and now I have great pressure every time I feel a glass of water. This works with other types of filters

Working as it should. In my area When it is fully charged it holds 6 quarts of water.

Update: this tank eventually failed possibly due to high incoming city water pressure ( I was not using it with an RO system, just a regular carbon filter). I contacted the seller and in less than an hour they made everything right and also gave helpful advice to prevent any future problems. THANK YOU! If you are using an RO system without a pressure tank like this one, a 1/4" line takes a couple minutes or longer to fill a 2L jug. With this 3 gallon it is now so much faster to fill a pitcher. 15 seconds instead of several minutes. This is a small purchase but it really solved an annoyance of waiting for filtered water. I flushed it one time before I drank from it, and have not noticed any odors or sediment at all. Big bonus points for having the quick connect valve included, it is a cheap part but if sold separately will set you back 5 or 10 bucks.
