On March 2, 1988, WaterSoft was purchased by Amtrol Inc. Over 30 years prior to the purchase of WaterSoft, Amtrol introduced the first pre-pressurized diaphragm expansion tank to the water systems industry. At that time Amtrol was the leading manufacturer of water systems tanks in the world and was looking to enter into water treatment.
Eventually both Jim and Bill Chandler moved on to pursue other opportunities and Amtrol moved WaterSoft out of the Ashland facility.
Almost 20 years later, in June of 2008, Bill Chandler acquired the Water Soft division back from Amtrol and moved production back to Ashland.
The current WaterSoft staff has over 150 years of combined water treatment experience.
