4.4 Gallon Amtrol tank
I had purchased a complete 4 stage RO system with a Taiwanese tank. When received new the tank wasn't pressurizing the water properly, and when I tried to check the air pressure in the tank, water was forced out of the air valve. So the new bladder had a hole in it somewhere. I ended up taking 3.1/2 litres of water out of the "air" side of the bladder, but not only that, about 20% was fine rust particles. I decided then that I would never consider another Taiwanese tank and only wanted the best. So, based on their reputation, I imported the Amtrol tank from America. The tank is doing everything I expect of it, but being realistic, I can't really comment on how good it is until I find it is still working correctly in 8 to 10 years.

Great tank
I bought this tank to replace another brand that was slightly smaller. This tank came with the right amount of pressure in it, and leaves no taste to the water. Couldn't be happier. Quick delivery too.

Amtrol tanks are high quality and manufactured in the US. I have 4 Amtrol tanks in service now for my home and greenhouse RO system. Some have been in service for 2 years with no problems. Isopure ships promptly and accurately.

Longest Life
It was time to finally replace my tank but these tanks last a really long time. I am using my old tank for almost 8 years......It provided great pressure water until now without any problem. I just purchased this brand again and I'm really happy it arrived so quickly.\
