How To Choose The Right Scalemaster Water Softener
1. Match It To Your Home Size
Smaller and standard homes will usually suit the SL150 or SL-S. Larger homes should look more closely at the SL-X or SL-Twin.
2. Check Your Water Demand
If your household often uses water from several outlets at the same time, choose a model designed for higher flow and greater demand.
3. Think About Installation Space
The SL-S, SL150 and SL-Twin are more compact choices. The SL-X is larger and may need a kitchen, utility room or garage position.
Single Tank vs Twin Tank Scalemaster Water Softeners
A single tank softener is a strong choice for most homes. It is compact, efficient and usually more than enough for normal daily use.
A twin tank softener is the better option when you want continuous soft water. While one tank regenerates, the other continues supplying softened water, making it ideal for busier households.

- Mechanical metered operation
