American Valve ScaleRX 1" FAQ

What is the difference between the 3/4" and 1" ScaleRX models?

The 1-inch SCALERX1 model features larger 1-inch Female NPT connections and a higher maximum flow rate of 17.6 GPM (compared to 14.1 GPM on the 3/4" unit) to accommodate 1-inch main supply lines without restricting volume.

Does the ScaleRX 1" soften water or remove minerals?

No. ScaleRX is a scale conditioner, not a salt softener. It does not remove beneficial minerals from the water, but alters their crystalline structure so hard minerals pass through the system without adhering to heat exchangers or pipe walls.

Does this unit require electrical wiring or maintenance?

No. The unit operates passively via fluid movement and contains no electrical components, salt tanks, or cartridges that require replacement.

Can the ScaleRX SCALERX1 be installed outdoors?

Yes. The stainless steel housing is rated for both indoor and outdoor installations, provided ambient temperatures stay within operating guidelines and lines are protected from freezing.

Are mounting fittings or adapters included with the SCALERX1?

No. Standard 1-inch NPT threaded fittings or transition adapters to PEX, copper, or PVC must be supplied by the installer based on system requirements.
