COMPATIBILITY & APPLICATIONS

When to Use This Tank

The Amtrol 144-120 is engineered for residential and light commercial reverse osmosis systems requiring substantial water storage. The 1" NPT male fitting provides compatibility with larger RO installations where flow rate and storage volume matter. Amtrol's diaphragm design provides more complete water discharge than bladder tanks, meaning you get access to nearly all the stored water without stagnation. This tank does not include an automatic shut-off valve; you'll need to add the AK-144-120 for 1/4" systems or AK-144-120-3/8 for 3/8" systems. The steel construction and bottom-mount design make this ideal for installations where durability and stable mounting are priorities, particularly in mechanical rooms, basements, or commercial settings where space allows for the 16" diameter footprint.

💧 Amtrol invented RO tank technology in the 1980s and still manufactures in the USA with a 5-year warranty that actually means something. The diaphragm design in this tank delivers more usable water and longer service life than cheaper bladder tanks that look similar but fail sooner.
