Common FAQs
What is the difference between the Harvey Arc and TwinTec S4?
The Harvey Arc includes app-focused features and is sold through a different route, while the TwinTec S4 remains one of our recommended online options for many homes.
Do I need a Big Blue model for my home?
Not usually, unless you have a large home with significantly higher water demand. For standard family homes, the TwinTec S4 is usually more suitable.
Is the TwinTec Cobalt better than the S4?
The Cobalt has a different design and app-focused features, but its technical specification is similar to the TwinTec S4 and availability is more limited.
How long will a Harvey water softener last?
This depends on the model, installation, usage and servicing. Newer Harvey models are known for strong long-term performance when properly maintained.
