The Aquatell 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. The Clack WS1 is a metered control valve and regenerates based on water consumption, dramatically minimizing salt consumption.

Great Product

I was very happy with the process of ordering. Setup was a breeze and the help and assistance to fine tune the unit was great. One thing I would find helpful is to have the unit come standard with Shark Bite fitting instead of the plastic threaded fittings. It was a bit difficult to get them to stop leaking. Shark Bites would have been a lot easier and less hassle. Otherwise very satisfied and uses way less salt than I had anticipated. Thanks for the great product.

Excellent customer support

Purchased a water softener. Had quite a few questions before and after purchase. Reid offered extremely detailed responses and replied very quickly. Made the buying and installing process less painful. Would defiantly recommend their products in the future.

Clack WS1 1.5ft3 water softener

Reid was very helpful in choosing the best water softener to meet my families needs. I was ready to purchase a larger system but he was able to guide me into a unit that would more adequately fit my requirements. This saved me money. As well, I was provided with all the information needed to properly program my new system. Communication was great!

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.
