What it does for your water
The On The Go OTG3NTP3M 8,000-Grain Portable Water Softener is a portable / RV softener rated at 8,000 grains.
Divide its 8,000 grains by your water's hardness for the gallons it treats before it needs salt: about 800 at 10 gpg, or 400 at 20 gpg. It regenerates with table salt poured into the tank and a fresh-water flush, so harder water means more frequent regenerations.
The listing also gives features listed Portable; mounting Freestanding; power Manual; capacity stated as 800 gallons; model OTG3NTP3M; material Polypropylene.
The listing gives dimensions of 7 in (L) x 19.5 in (W) x 7.3 in (H) and hose, backflush, in the box.
