  • For application where continuous supply of soft water is needed we offer dual tank softeners with WS1EE the Twin Alternating Control Valve. All Clack series water softeners are preassembled and come complete with 18” x 30” or 14" x14" x 34" brine tanks, by-pass and 3/4" or 1” brass lead free plumbing connectors. Canadian Water Warehouse offers a full technical support, installation and service. Our Softeners are covered with 5 years warranty on Control Valve and 10 years on the resin and brine tank. Twin alternating water softeners are ideal for situations where uninterrupted and continuous flow of soft water is a necessity. One of the two resin tanks is always in service, while the other tank is on standby. When the softening capacity is reached in resin tank #1 the Clack WS1EE Meter Control Valve will switch the tank from standby to service for resin tank #2. The tank containing the exhausted resin in tank # 1 will be regenerated and set on standby until the other tanks’ capacity is reached and is ready for regeneration.
