The 14 gallon tank holds 3 times more water than the standard 4 gallon tank. It's an excellent upgrade if the family or office wants to have plenty of pure water readily available (10+ gallons).
We recommend this option if you want to install the RO system in the basement or garage, and feed pure water to multiple outlets 20-40 ft away. The high water volume in the tank will help maintain strong delivery pressure to your remote output points.
Dimensions: 16" x 16" x 22" height (plus 4" height for tank shut-off valve)
The tank works fine standing up or laying down on its side. So if you lack headroom or don't have enough space near the RO system, you can lay the tank down or put it elsewhere within 20-30 ft horizontal, and 10-15 ft vertical from the RO, and it will work fine.
