tankRO – RO Water Filtration System Expansion 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.

Good smaller alternative to a 3 gallon tank
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.

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