Better in Every Way

The tank this is replacing was way more expensive and was of lower quality. You can tell it was a bit more flimsy than this one, that's why it failed on me after just a single year. This one I expect to far surpass that

dont hesitate to upgrade if your tank is too small

The extra storage is so convenient! We never run out of clean water now.

Conveniece Upgrade

The original tank that came with the system held less than 2 gallons, I decided to double the storage amount with this one.

Convenient

The extra water in reserve that this tank allows is just for convenience. We noticed that we would often run out of water in storage and have to wait a bit for more, especially during the summer (or whenever we had a heat wave). Ever since we installed this new tank, we haven't depleted our water reserve once.
