The Aqualux Clack WS1 water softener features the sophisticated and high-flow Clack WS1 metered electronic control valve, Structural composite tanks, brine tank safety float, and 10% cross linked resin. With 1" internal porting, it's the perfect softener for homes requiring more than 10 gallons per minute of flow. Easy access to all internal components, make the Clack valve and excellent choice for do-it-yourselfers and professionals alike. Soft water brine refill ensures a complete regeneration, and keeps internal components free of performance-degrading sludge.

Great service and support

I Purchased a Clack WS1 Water Softener through Aqualux. The support I received through the process of identifying my requirements, delivery and post delivery setup was excellent. I would not hesitate in recommending Aualux.

So Far so Good

Clack Meter Valves have an excellent reputation. Aquatell did a good job packing and sending the water softener system. Aquatel provided excellent advice about installing the resin in the tank and ******** on the valve. Aquatel provides excellent generic information on the Web site relating to correctly sizing a water softener system. However, there was not much specific information relating to Clack valves on the Aquatell Web site.
