GGN-Tank-9-9 Gallon RO Reverse Osmosis Tank with 1/4" NPT Stainless Steel Connector (Blue)

If one is questioning the actual volume this tank holds one can go online to a tank volume calculator and enter the measurements and see it’s 9.75 gallons. Of course we know it has an air bladder in it that will reduce the volume of water somewhat. I’m satisfied with the tank and installed it with a splitter so I’m utilizing my smaller tank that came with my filter unit alongside the new tank. It works for me.

Does not hold 10 gallons. Even if it had no bladder it would not hold 10 gallons. It has 6 gallons at best.Sent the seller a message and they try and tell you that it's 10 gallon but because of the bladder it can not hold 10 gallons. Thats a bunch of BS.

IT"S NOT 9 GALLON TANK!about the same size as a 5 gallon paint bucket.

I have been installing and servicing reverse osmosis for 30 years and I know for a fact that this is not a 9 gallon r.o tank. I have installed hundreds of 9 gallon r.o tanks. This looks more like a 4 to 6 gallon tank.Update on this tank... I checked with the Water quality Association this tank is not certified to be a 9 gallon tank. This company will send you uncertified documents about this tank. But even Common sense will tell you it's not a 9 gallon tank. If you put it up to a 5 gallon bucket you can tell the bucket is bigger. I wrote amazon about this and the company and neither one helped me with this issue. I am very upset about this and so is my customer that I put this tank in for.
