Frequently asked questions

What size WS1 softener do I need?

WS1 simplex softeners range from 75L to 200L+, and duplex configurations cover 200L and above. Sizing depends on household or commercial demand and local water hardness — contact us if you're unsure which capacity fits your needs.

What's the difference between simplex and duplex WS1 valves?

A simplex valve uses a single tank, so soft water isn't available during regeneration. A duplex valve alternates between two tanks, ensuring continuous soft water supply even while one tank regenerates — better suited to higher-demand or commercial settings.

Are Clack WS1 parts interchangeable across models?

Many internal parts are shared across the WS1 range, but always check your specific valve model before ordering, since capacity and configuration affect fit.
